February Is Low Vision Awareness Month

Help for People With Vision Loss

Here’s eye-opening news: Currently, 4.2 million Americans ages 40 and older are visually impaired. Of these, 3 million have low vision. By 2030, when the last baby boomers turn 65, the number of Americans who have visual impairments is projected to reach 7.2 million, with 5 million having low vision. For the millions of people who currently live or will live with low vision, the good news is there is help.

But first, what is low vision? Low vision is when even with regular glasses, contact lenses, medicine, or surgery, people have difficulty seeing, which makes everyday tasks difficult to do. Activities that used to be simple like reading the mail, shopping, cooking, and writing can become challenging.

Most people with low vision are age 65 or older. The leading causes of vision loss in older adults are age-related macular degeneration, diabetic retinopathy, cataract, and glaucoma. Among younger people, vision loss is most often caused by inherited eye conditions, infectious and autoimmune eye diseases, or trauma. For people with low vision, maximizing their remaining sight is key to helping them continue to live safe, productive, and rewarding lives. The first step is to seek help.

“I encourage anyone with low vision to seek guidance about vision rehabilitation from a low vision specialist,” advises Paul A. Sieving, MD, PhD, director of the National Eye Institute (NEI), one of the National Institutes of Health (NIH) and the federal government’s principal agency for vision research.

What is a low vision specialist? A low vision specialist is an ophthalmologist or optometrist who works with people who have low vision. A low vision specialist can develop a vision rehabilitation plan that identifies strategies and assistive devices appropriate for the person’s particular needs. “A vision rehabilitation plan helps people reach their true visual potential when nothing more can be done from a medical or surgical standpoint,” explains Mark Wilkinson, O.D., a low vision specialist at the University of Iowa Hospitals and Clinics and chair of the low vision subcommittee for the National Eye Health Education Program (NEHEP).

Vision rehabilitation can include the following:

Training to use magnifying and adaptive devices
Teaching new daily living skills to remain safe and live independently
Developing strategies to navigate around the home and in public
Providing resources and support

There are also many resources available to help people with low vision. NEI offers a 20-page, large-print booklet, titled What You Should Know About Low Vision, and companion DVD, featuring inspiring stories of people living with low vision. This booklet and DVD, among other resources, are available at
www.nei.nih.gov/lowvision.

With the aging of the population, eye diseases and vision loss have become major public health concerns in the United States. NEI is committed to finding new ways to improve the lives of people living with visual impairment. Aside from making information and resources readily available, NEI has dedicated more than $24 million to research projects on low vision, including learning how the brain adapts to vision loss; strategies to improve vision rehabilitation; and the development of new technologies that help people with low vision to read, shop, and find their way in unfamiliar places. Research like this will help people with low vision to make the most of their remaining vision and maintain their independence and quality of life.

The National Eye Health Education Program (NEHEP) of the National Eye Institute (NEI), a part of NIH, offers a 20-page, large-print booklet, titled What You Should Know About Low Vision, and a series of videos featuring patient stories about living with low vision. These and other resources are available at http://www.nei.nih.gov/lowvision.

Taking Control of Glaucoma

Taking control of glaucoma: The importance of adherence to glaucoma treatment

Glaucoma is known as the “silent thief of sight”: people with glaucoma usually have no symptoms. The only intervention that has been proven to reduce the risk of vision loss in glaucoma is lowering the eye pressure. The most common way to lower eye pressure is with eye drop medications. Glaucoma treatments do not improve vision, but they do to help prevent vision loss from happening.

What does it mean to be “compliant”?

Adherence (the newer term that is replacing “compliance”) with glaucoma treatment usually means taking your eye drops everyday and at the right times and coming to your glaucoma check ups. Your doctor needs to check your eye pressure regularly, as well as look at your optic nerves and measure your visual fields, to monitor your disease.

Why is it difficult to take eye drops everyday?

Some people with glaucoma only need 1 or 2 eye drops everyday to control their glaucoma, but some may need as many as 4 glaucoma medications, taken multiple times throughout the day. Imagine using 2 eye drops in the morning, 1 eye drop at noon, 1 at dinnertime, and 2 more in the evening, and doing this everyday for years and years, to help protect your sight. It is easy to see how people could miss some drops. Reasons can include forgetting them (or falling asleep before that bedtime drop), the cost of the medications, the side effects from the eye drops, and many others.

Why is adherence important for glaucoma patients?

In one word: blindness. The eye drops lower the eye pressure, which helps protect the eye from loosing vision from glaucoma. If a patient does not put in their eye drops, then the eye pressure will not be as low as it needs to be during that time and eye can be damaged. The damage from glaucoma is not reversible, so prevention is the goal.

What can you do?

If you have glaucoma and you take eye drops, use them everyday and as close to the right time as possible. Also, see your doctor for your glaucoma check-ups. Ask about your eye pressure readings, your optic nerve appearance, and your visual fields, so that you know what’s going on with your disease. If you are having any trouble getting your drops in (for example, increased cost due to change in insurance, always forgetting the morning drop, red eyes drawing attention at work), then tell your doctor about it, so you can make changes in your treatment plan.

Friends and family members can help, too. If someone you care about has glaucoma, think about asking them if they need any help with their drops. Some ways you might help: look at videos to see eye drop techniques, put in the drops for them, provide gentle reminders, or go with them to doctor’s visits to be a “second set of ears” on instructions and recommendations.

Taking eye drops for glaucoma is not easy, but it does work. Most people who are treated for glaucoma do not go blind. Take control of your disease, by taking your eye drops and going to your glaucoma check-ups.

Glaucoma Awareness Month

In recognition of Glaucoma Awareness Month, here is a list of the top 20 things you should know in order to help save your vision as you get older.

What is Glaucoma?

1. Glaucoma is not just one eye disease, but includes a group of eye conditions that are a result of damage to the optic nerve thus causing vision loss. While unusually high pressure inside your eye (known as intraocular pressure – IOP) is often the cause, this may not always be the case.

2. It is one of the leading causes of vision loss in the US, and left untreated can result in blindness. It is estimated that 2.2 million people in the US have glaucoma, but only half of them have been diagnosed. While it primarily affects those over 60, it affects all ages with 1 in 10,000 babies born with glaucoma in the US.

3. The two most common types of glaucoma are primary open-angle glaucoma and closed angle glaucoma. Fluid in the eye flows through and area between the iris and the cornea and drains through the trabecular meshwork – this area is the “angle.”

Symptoms

4. Often call the “silent thief of sight,” open angle glaucoma, which affects 90% of those diagnosed, is not indicated by eye pain. There is a gradual loss of peripheral vison, generally in both eyes, and in the advanced stages there is tunnel vision.

5. The symptoms of closed angle glaucoma are easier to recognize and include eye pain, blurred vision, nausea and vomiting, vision issues in low light, halos around light sources and red eyes.

What to Expect From a Glaucoma Exam

6. Tonometry to measure your intraocular pressure. Your eyes will be numbed with eye drops making the procedure painless.

7. Dilated eye exam to look through your pupil to the back of your eye and the optic nerve.

8. Visual field test to check your peripheral vision.

9. Visual acuity to test your ability to see at a distance.

10. Pachymetry to determine the thickness of your cornea. Your eyes are numbed so this will be painless.

11. Gonioscopy to check the angle in the eye where the iris meets the cornea to help determine between open angle and closed angle glaucoma.

Treatment Options

12. Eyedrops are a common treatment options and may include more than one type. The importance here is to let your doctor know your complete medical history and comply completely with your doctor’s instructions to get the desired result. All include side effects and your medical history will allow your doctor to select the safest option. Some examples include:

Prostaglandins – they increase the outflow of the fluid in your eye and reduce internal pressure.
Beta Blockers – they reduce the production of fluid in the eye.
Carbonic anhydrase inhibitors – they reduce the production of fluid in the eye.
Cholinergic or miotic agents – they help increase the outflow of fluid from the eye.
Alpha-adrenergic agents – they reduce the production of fluid in the eye and increase the outflow of fluid.

13. Oral medications, such as carbonic anhydrase inhibitors, will be used if the eye drops cannot bring your eye pressure down on their own.

14. Surgery is an option if the medications or don’t work or you can’t tolerate them. In some cases you may need to continue using eyedrops. Surgeries include:

Trabeculoplasy – laser is used to unblock clogged drainage canals.
Viscocanalostomy – laser used to remove a small piece of the trabecular meshwork.
Aqueous shunt implant – small tube is inserted into the eye to improve drainage of the fluid.

Risk Factors

15. Age – you are 6 times more likely to get glaucoma if you are over 60.

16. Family history – you are 4-9 times more likely to get open angle glaucoma if someone else in your family has it.

17. Ethnicity – it plays a big factor in being diagnosed with glaucoma:

African Americans are at a higher risk than Caucasians of developing glaucoma; develop it earlier and experiencing permanent blindness.
Mexican-Americans have a greater incidence than Caucasians.
Asians are at increased risk for closed angle glaucoma, with people of Japanese descent being at higher risk for normal tension glaucoma.

18. Steroid use – long-term use increases the risk by as much 40%.

19. Medical conditions – such as diabetes, high blood pressure and hypothyroidism.

20. Other eye conditions – blunt injuries that “bruise” they eye (most commonly sports-related), retinal detachment and eye tumors, eye inflammation and certain eye surgeries are examples that increase the risk.

You can work to prevent, or at least lessen the effects of glaucoma on your vision by getting regular comprehensive eye exams, use any eye drops prescribed by your doctor to treat eye pressure according to their instructions, eat a healthy diets and wear eye protection to prevent eye injury.

Spotlight Text – A New Way to Read

For People With Low Vision There Is Spotlight Text – A New Way To Read

Spotlight Text is a new e-reading app specifically designed to address the needs of patients with eye disorders. Dr. Howard J. Kaplan, a retina surgeon in the Hudson Valley, started developing the app five years ago. Dr. Kaplan states, “When the first Amazon Kindle came out, a light bulb went off. If books are now digital, you can make the text of the book adapt to the reader instead of forcing the reader to adapt to the text. My patients were extremely frustrated with low vision devices such as desktop readers. Most found them very difficult to use and affordable.” Working with low vision experts at the Lighthouse Guild International, various text presentation methods were evaluated. “The app is based on real visual science and was built with the input of the top low vision specialists in the country, “ says Dr. Kaplan.

The greatest difficulty in creating the app proved to be getting access to e-books. Initially Dr. Kaplan approached the major e-content providers such as Amazon, Google, and Barnes & Noble. All of them considered the low vision market too small to address. During the 5 years, Bookshare, a Silicon Valley nonprofit, began to expand exponentially. Bookshare is dedicated to creating an accessible library for the print disabled.

How Spotlight Text Works, and What Makes it Different
The app is seamlessly tied into the e-book library of Bookshare. The library currently has 300,000+ titles including all current and recent NY Times bestsellers. It has a very extensive collection of textbooks for K-12 children. E-book downloads are free and unlimited for children, and Vets. There is a minimal joining/maintenance fee for adults. All patients that have any visual deficit that prevents them reading standard print are eligible to join. A physician, optometrist, therapist, or even librarian has to certify a patient by checking a single box on the form and signing their name. Bookshare then does the rest by contacting the patient and giving them an account. Bookshare functions due to an exception in US copyright law that allows the free distribution of copyrighted material in formats that are unique for patients with visual disabilities. The books are coded in DAISY, which is a sound file format. The App takes these files and renders them back to written text.

The user interface is designed such that an 80-year-old technophobe or a five-year-old child can easily use it (Apple-like minimalism). The app also synchronizes with Bluetooth Braille readers that convert the text to Braille. It can be connected to the HDMI port of any TV for unlimited screen size (hardwire or wireless through Apple TV). As you will see when you demo the app, text is now dynamic: in both teleprompter and marquee modes the text will move so that ocular movements are minimized. Marquee mode was specifically designed and tested to work for end-stage Retinitis Pigmentosa patients and any patient with only a remaining very narrow central visual field. Using VoiceOver all books are now audible books.

Social Entrepreneurship
Special iTunes links are created for vision nonprofits. If a patient clicks on those links and purchases the Spotlight Text App, 50% of sales profits are donated to the organization, including the Discovery Eye Foundation or the American Academy of Ophthalmology Foundation. Prior to being placed on the AAO’s website the app was evaluated by its Low Vision Rehabilitation Committee. It is the only app that the American Academy of Ophthalmology has ever endorsed.

The Future
Dr. Kaplan hopes to return to the major providers of e-content and persuade them that low vision and blind users are a viable market for them.

“I believe universal accessibility is achievable, but it will take a coordinated and combined effort. Reading is such a vital part of all our lives, with e-books, everyone should be able to enjoy a good book.”

Hadley’s Online Education for the Blind and Visually Impaired

12/4/14

The Hadley School for the Blind (www.hadley.edu) is the world’s largest educator of people who are blind or visually impaired as well as the world’s largest Braille educator. The school’s curriculum has always been delivered completely through online education, meaning students can study from anywhere at any time. Hadley serves nearly 10,000 students in all 50 states and approximately 100 countries. Hadley serves adult students, age 14 and over. Our mission is to promote independent living through lifelong, distance education programs for individuals who are blind or visually impaired, their families and blindness service providers.

Hadley courses are tuition-free for people who are blind or visually impaired and their family members; there is modest tuition for professionals. Students study at their own pace and receive personalized, one-on-one instruction from their instructor by phone, email, virtual “office hours” or mail.

Students can take courses in four formats: large print, Braille, audio or online. Since we began offering courses in an online format in 2002 as part of our eHadley initiative, more than 13,000 students have completed one or more online courses. 89 of our approximately 100 courses are offered in an online format, and 20 new online courses were introduced in 2014. Most of our online courses also are now accessible on mobile devices, so that students can literally study on the go if they choose.

If you’re not familiar with blindness, you may be asking yourself how a blind person can take courses online. The answer is through adaptive technology, such as screen magnifiers or screen readers. A screen reader is a software application that converts text on a screen to speech. One of the most popular is called JAWS. If a student doesn’t know how to use a screen reader, Hadley has a series of courses to teach them how to use this technology!

While many students come to us to learn to read and write Braille, we offer much more than just Braille education. In addition to Braille, some of our most popular areas of study include access technology, independent living skills, employment skills and recreation. These courses fall within Hadley’s Adult Continuing Education Program, which represents the largest number of students at Hadley. Some examples of ACE courses include:

Independent Living Series: This series of two-lesson courses focuses on a variety of topics central to the tasks of daily living. When individuals lose their sight, it can be overwhelming. They must relearn key daily living skills, such as cooking, dressing themselves and getting around. These courses give our students the tools they need to retain their independence and lead productive lives. The individual course topics include: orientation and mobility basics; clothing care and dressing confidently; socializing and dining; and cooking.

Self-Esteem and Adjusting with Blindness: Whether a student was born visually impaired or lost vision later in life, this course will help them understand the adjustment to life’s demands. Maintaining self-esteem with the changes and adaptations that come with blindness are discussed in-depth and illustrated with quotes from many blind persons.

Human Eye 1 and 2: These courses explain the parts of the human eye, how it works and how corrective lenses work. They enable the student to describe the basic anatomy, routine examination procedures and some common conditions of the human eye. Hadley also offers courses on some of the specific conditions that can lead to vision impairment, including: macular degeneration, diabetes and glaucoma. These courses are designed to help students living with these conditions to better understand them and how to manage them.

Developing Your Technology Toolkit: Technology plays a significant role in how people interact with each other, and most will likely encounter some aspect of technology in their everyday life. This course presents a variety of prominent desktop and mobile solutions. It also discusses how adaptive technology solutions provide access to mainstream hardware and software. In addition, it focuses on proprietary, adaptive technology products designed to be used specifically by persons who are visually impaired.

Enjoying Bird Songs: Listening to birdsongs helps people reduce stress, improve cognition and memory, interact with nature and even have spiritual experiences. This course guides students through the many bird songs presented in Hadley student John Neville’s audio CD set Beginner’s Guide to Bird Songs of North America. This course helps students become able to appreciate nature and birdsongs, as well as reflect on their experiences with birdsong.

Also part of the ACE program is the Forsythe Center for Employment and Entrepreneurship (FCE), designed to address the 70 – 80% un- and underemployment rate among people who are blind or visually impaired. The FCE is not an academic, college-level business program, but instead was designed to provide the requisite computer training; relevant social security, tax, accounting, legal, marketing, management and communications information; and content specific to the needs and concerns of visually impaired individuals who want to launch and grown their own businesses. All FCE courses are online, and many are just one-lesson modules, which makes learning quick and easy. Some examples of modules include: The Marketing Plan, The Business Plan, Forms of Ownership and Networking Skills.

Since the 1930s, The Hadley School for the Blind also has offered a nationally-recognized, accredited High School Program, available to students with visual impairments age 14 and up who live in the United States. Students may transfer credits from courses taken at Hadley to their high school to graduate locally. Students may also earn their high school diploma directly through Hadley. Frustration with local schools not offering quality vision services or accessible formats, difficulties passing the state-required exit exam for graduation or inability to travel long distances have prevented many of our students from earning their diploma in the past, so the Hadley High School Program is a much-needed “second chance.”

Courses are supplemented by Seminars@Hadley, free 60 to 90-minute webinars that are available to the public. These seminars are designed to bring together our blind and visually impaired students from around the world to discuss various topics in a virtual conference room with a panel, moderator and guest speakers. Participants listen to the seminar from their computer and post questions electronically. They also ask questions and/or make comments using a microphone. Seminar topics are timely, practical and determined by what our students tell us they need. Some of our most popular seminars include: Learning to Put the “You” in YouTube, Simplifying Internet Searching and Crafting with Vision Loss. Some seminars are approved for Continuing Education Credits (CEUs).

Hadley also offer a series of instructional videos on YouTube called iFocus (www.youtube.com/hadleyschool). These videos explain how to use the vision accessibility features on iDevices (Apple products such as the iPhone and iPad). Each video focuses on a specific task on iDevices, such as sending a text message or creating a calendar event . There are now 25 videos in the series, and they have been viewed nearly 10,000 times!

For more information about Hadley or to enroll, visit our website at www.hadley.edu, call our Student Services Department at 800-526-9909 or send an email to student_services@hadley.edu.

E-Readers for Low Vision

11/18/14

While the devices mentioned in the November 13th post will help you read a hardcover or paperback book, what about an e-reader?

E-Readers for Low Vision

These lightweight portable devices come with a variety of options for people with limited vision, at a more moderate cost. The two we will look at are the Kindle and the Nook.

Kindle

There are two options here, an e-ink reader (the Paperwhite or the new Voyage), the closest to reading a paper page, or a full-color tablet. The only accessibility options for the e-ink readers are the ability to select a font you find easy to read and the ability to increase the font size. The increase in font size is a big help, but remember, that as you increase the size you will be “turning the page” more often – the screen size is 6” diagonally. The Voyage has a whiter background than the Paperwhite allowing for more contrast. Both include a built-in screen light that can be adjusted to your needs. One thing to note is that while it does have a screen light, it is not a backlit display as you will find in the Fire HDX. This might mean less eye strain.

The Fire HDX is a full-color tablet with quite a few more accessibility options and the screen sizes range from 6” to 8.9”. Since it is a full functioning tablet you can access email, play games, watch videos and a variety of other things. It has more large-font options (that can even be used for your emails), a screen magnifier that is easily activated with a triple tap on the screen and you can pinch to adjust the zoom and the backlit display provides high contrast. There are other options for people that are blind including a screen reader to describe actions taken on your screen, five accessibility shortcut gestures to help you navigate and even Braille support with a free app from the Amazon App Store. Because it is a backlit display you may experience eye strain if you don’t occasionally take reading breaks.

Kindle also has a free accessibility plugin that is downloadable for your Windows PC. It provides the following features: text-to-speech reading, voice-guided menu navigation, large font sizes, high contrast reading mode, keyboard navigation and accessible shortcuts. It is compatible with JAWS, NVDA and Microsoft Narrator.

Nook

Nook, like Kindle, has two options. An e-reader called the Nook GlowLight and a full-color tablet called the Samsung Galaxy Tab 4 Nook in 7’ and 10.1” sizes. As with the Kindle e-ink reader, the only accessibility options are the font and font size. There is also a built-in light to make the page brighter.

The new full-color tablets now made by Samsung, provide you with the access of a full functioning tablet such as email, playing games, watching videos, etc. The vision accessibility options include screen magnification for the text and pictures, TalkBack which reads aloud menus and on-screen options for navigating the device, negative colors to invert the color of the screen (text that usually appears black on white will be shown white on black), color adjustment if you are color-blind, and a text-to-speech option that will allow you adjust the rate at which text is spoken and your preferred text-to-speech program. Once again, these tablets have backlit screens that may tire your eyes after an extended period of reading, so take breaks.

E-Book Formats

The Kindle and Nook each have their own proprietary book formats, meaning that you can only read a book purchased for the Kindle on a Kindle or a Nook book on a Nook, however EPUB and CBZ formats can be easily transferred to the Nook. This is more important when it comes to borrowing e-books from a library. The EPUB format is more common when e-books are offered; and while some libraries now offer Kindle books, there are more EPUB titles. If you are comfortable with technology, you can use Calibre to convert most formats into whatever format you need.

Choosing between a Kindle and a Nook is based on personal preference. You can try out both devices before you buy them at Best Buy or Staples for the Kindle and at Barnes & Noble stores for the Nook. If you already own an iPad or Android tablet, remember you can also download the free Kindle and Nook apps from the App Store or Google Play.

For Book Lovers – Low Vision Magnifiers

11/13/14

The first of this month was Book Lover’s Day, and as an avid reader, I am willing to celebrate any day that is about reading. However, if you suffer from low vision due to age-related macular degeneration, cataracts, retinitis pigmentosa or other sight-threatening eye diseases, you may not be able enjoy reading as much as you used to.

There are several options to help you enjoy books again, including low vision magnifiers, e-books and tablets. We will provide you with a quick primer to help you select the best option for your lifestyle and budget. Today we will look at magnifiers and Tuesday we will explore e-readers and tablets.

Low Vision Magnifiers

There are several general classifications for magnifiers –

• Hand-held magnifiers – These are smaller and more portable, allowing you to read thins such as menus, price tags, prescription bottles and ingredients in addition to books. Some also come with built-in lighting that can help you see in low light situations. They can be as simple as a single glass lens to more advanced digital devices that can auto-focus, change text color and magnification or even let you snap a picture of what you are reading if steady hands are an issue. However, because of these are small enough to make them portable, the field of vision is small and reading books for any length of time might become tedious.

• Stand magnifiers – These are really better for reading books, magazines and newspapers as the field of vision is larger, your hands will not get tired holding the device and the distance between the page and the magnifier will remain more constant, making reading easier. This is especially important if you have tremors. However, these require sitting at a desk or table to be used.

• Magnifiers mounted on reading glasses – These are great for being “hands-free,” but they also limit your ability to see at varying distances, and are generally used for seeing things less than a foot from your nose.

• Video magnifiers – These devices use a video camera (similar to the portable digital device listed above) that focuses on the page and then magnifies it for viewing on a screen or monitor. Text color/background, brightness, contrast and levels of magnification can be adjusted as needed. As with the stand magnifiers, the ones able to scan an entire page of a book need to be used at a desk or table. However, now there are some machines that will even read out loud to you!

To get an idea of the range of devices available, along with the wide range of prices, here are three websites to get you started – Enhanced Vision, Optelec and Humanware.

Because each person has a different vision issue, not one magnifier works for everyone. A person with central vision loss from age-related macular degeneration will have different needs from a person with peripheral vision loss from glaucoma. That is why we suggest that you consult with a low vision specialist to help guide you in selecting the correct device for your specific needs.

Check back on Tuesday, or subscribe to the DEF blog, to learn about e-reader and tablet options for people with low vision.

Diabetes Awareness Month & Diabetic Eye Disease

11/11/14

Even though people with diabetes are at a greater risk of developing blinding eye diseases, a recent study of Medicare beneficiaries show that very few of the people at risk have a preventative yearly eye exam.

Facts About Diabetes

In the US there are 29.1 million that have diabetes, 21 million have been diagnosed and 8.1 million are undiagnosed. Unfortunately, if left undiagnosed or untreated, diabetes can lead to serious health problems such as high blood pressure, increased LDL cholesterol, heart disease, stroke, kidney disease and blindness.

Although African-Americans and Hispanics are more likely to have diabetes, less than a third are aware of diabetic eye disease. And for those that have been diagnosed with diabetes, where a yearly eye exam is considered essential, ¾ of them have not had an eye exam in five years.

Diabetic Eye Disease – 3 Ways Diabetes Affects Vision

Diabetic retinopathy affects 28.5% of people 40 and older that have been diagnosed with diabetes. It happens when the blood vessels in the retina are damaged by leaking or blocking blood flow to the retina (the source of your central vision for reading, driving, recognizing faces, etc.) and if untreated, it can lead to complete blindness. In the very early stages there are no symptoms. And while there are some treatments that may help slow the progression of the macular edema, there is no way to regain sight that is lost.

Cataracts occur when there is a clouding of the eye’s lens, making your vision blurry or cloudy. While it is a normal for this to happen as a person ages, someone with diabetes is more likely to develop them at an earlier age. While beginning cataracts can be treated with glasses, when they become more advanced, cataract surgery will be needed to replace the cloudy lens with an artificial lens.

A person with diabetes is nearly twice as likely to get glaucoma as other adults. Glaucoma is an eye disease that damages the optic nerve. The damage occurs when the pressure in the eye increases, squeezing the optic nerve and restricting its visual transmissions to the brain. Like diabetic retinopathy, you rarely notice any changes in your vision in the early stages, but as it progresses you begin to lose your peripheral vision. It can be treated with eye drops or surgery, but left untreated it can result in blindness.

Controlling Diabetes

Diabetes can be controlled, and some cases prevented, with careful attention to diet, watching your weight and exercise. Also learn your family medical history. You are at a higher risk of diabetes if a mother, father, brother or sister has the disease. If you are diagnosed with diabetes, make sure you have a yearly comprehensive eye exam to avoid vision loss. To learn more about diabetes go to www.ndep.nih.gov.

Night Blindness

10/28/14

As the number of daylight hours decrease and daylight savings time is about to end, many of us feel that the days are getting much shorter. If you suffer from night blindness, your days are shorter, because getting around or driving at night, are sometimes impossible.

Night blindness is a condition that makes it difficult for a person to see in low-light situations or at night. Some types are treatable, while others are not. You will need to consult your eye doctor to determine the underlying cause of your night blindness to determine what can or cannot be done.

There are several things that could cause night blindness:
•Cataracts
•Genetic eye disease
•Vitamin A deficiency
•Diabetes
•Aging eye
•Sunlight exposure

Here is a brief look at each.
Cataracts – This is when the lens of the eye becomes gradually becomes clouded, reducing vision. Besides reducing vision at night you may also experience halos around lights. This is a treatable condition requiring cataract surgery and replacing your clouded lens with a clear artificial lens. Your vision should improve considerably.

Genetic Eye Disease – Both retinitis pigmentosa or Usher syndrome are progressive genetic eye diseases where the rods that regulate light, and cones that control color perception and detail die. Progressive night blindness is one of the first visual symptoms of these two diseases. Currently there is no treatment for them as there is no way to treat or replace the dying rods.

Vitamin A Deficiency – While rare in the US, it can be a result of other diseases or conditions such as Crohn’s disease, celiac disease, cystic fibrosis or problems with the pancreas. Options to help with the deficiency include vitamin supplements suggested by your doctor, or increasing your intake of orange, yellow or green leafy vegetables.

Diabetes – People with diabetes are at higher risk for night vision problems because of the damage to the blood vessels and nerves in the resulting in diabetic retinopathy. Not only can it cause poor night vision, it may also take longer to see normally after coming indoors from bright light outside. There is no cure, but controlling blood sugar levels with medicine and diet can help prevent developing retinopathy or help slow the progression.

Aging Eye – As we age several things happen to our eyes. Our iris, which regulates the amount of light going into the eye, gets weaker and less responsive. This can make adapting from light to dark more difficult and slower. Our pupils shrink slightly allowing less light into the eye. The lens of the eye becomes cloudier, as explained above in cataracts, limiting the amount of light into the eye. We also have fewer rods for light perception. Aside from cataract surgery there is no treatment for age-related night blindness. However, eating a diet rich in fruits and vegetables and low in saturated fat is the best way to slow the progression. Here is more information on how the aging eye is affected.

Sunlight Exposure – If your night vision seems temporarily worse after a trip to the beach or a day on the ski slopes, it probably is. Sustained bright sunlight can impair your vision, especially if you fail to wear sunglasses or goggles.

Night blindness due to genetic conditions or aging cannot be prevented. However if you protect your eyes from extreme sunlight, eat a healthy diet, and monitor blood sugar levels if needed, you can reduce your chances for night blindness.

As we head into the holiday season, you should know that some great sources of vitamin A include sweet potatoes, butternut squash and … pumpkins!

20 Tips For Cooking With Low Vision

10/21/14

People cook for different reasons. Some just so they can eat, others enjoy the creativity and find it relaxing and for some it is a activity they have fun doing with others. But cooking can become difficult and dangerous as you lose your vision. Here are some useful tips to help keep you safe and give you confidence to enjoy cooking with low vision.

1. To avoid burns, place a pot or pan on the burner before turning it on and, turn the burner off before removing the pot or pan.

2. Turn pan handles inward from the stove or counter to avoid spills and burns.

3. Mark common or often used settings on appliances with bright nail polish, bright colored tape, or raised dots.

4. Purchase a microwave with a sensor reheat feature to automatically reheat food to the proper temperature.

5. Use long oven mitts to protect your hands and arms from hot surfaces.

6. Turn on the oven light while using it to remind you the oven is on.

7. Use a double spatula to help avoid spills when turning food.

8. Use a special measuring cup that enhances contrast.

9. Use a knife with an adjustable slicing guide.

10. Have light and dark cutting boards to be able to provide the most contrast depending on what you are slicing or chopping – such as black for slicing onions and white for chopping kale.

11. Use a large print, low-vision kitchen timer.

12. Use an automated coffee maker that makes a single cup of coffee or tea to eliminate the need to pour boiling liquids and risk burns.

13. Attach low-glare fluorescent lighting to the underside of cabinets to make it easier to see.

14. Outline the end of countertops with colored duct tape, or paint in a color that contrasts with the work surface. Also choose kitchenware that contrast with the countertop.

15. Organize shelves in a logical way, possibly alphabetically, with most use items easily accessible. Be sure to return items to where they were originally.

16. Use a color for the interior of cupboards that contrasts with your dishes to make them easier to see. Do not use clear glasses or dishes as they appear invisible.

17. If you have glaucoma and experience tunnel vision, remove cabinet doors or replace with sliding doors.

18. Place rubber bands around the milk carton to distinguish it from the orange juice carton. This also works well with distinguishing a can of chicken noodle soup from tomato, etc.

19. Avoid overflows by hooking a “liquid Level” indicator to your glass or cup that will play a tune when you are ¾” from the top.

20. For cold drinks you can also use your finger by placing the tip of it over the edge of the glass and stop pouring when you feel the liquid.

Once you have prepared your food, eating can also be a challenge, so here are five bonus tips.

1. Use dinner plates with a raised lip to avoid spills or pushing the food off while eating.

2. Avoid patterns on dinnerware.

3. Make sure your dishes contrast with the table or table linens.

4. Have a system for putting food on your plate such as meat at 6:00, vegetables at 3:00 and starches at 9:00.

5. Use a gooseneck lamp directly over you plate.
