Beauty is in the Eyes of the Beholder

I love the idea that beauty is in the eyes of the beholder. It reminds us that individuals can make choices about what they perceive to be true beauty.

Let’s consider art… one person’s beautiful can be another person’s junk. If beauty is in the eyes of the beholder, the question is – are we taking the time to appreciate all that surrounds us? From Mother Nature’s unlimited panoplies of possibilities to the innocent smile of a child, beauty is the catalyst that makes being alive the greatest of all human adventures.

I am sure you’ve heard the phrase “stop and smell the roses,” so why not take the time to stop and observe the beauty your eyes can behold.

The Discovery Eye Foundation is working every day to preserve your vision and give all of us the chance to see what’s truly beautiful and treasure it.  All you have to do is open your eyes and take a look.

Louis Armstrong said it well:

I see trees of green and red roses too.
I see them bloom for me and you.
And I think to myself,
what a wonderful world.

You’re right Louis… it is a wonderful world if we all just keep appreciating the beauty that’s out there for all of us.

OUR EYES WORK LIKE CAMERA’S!

The inner workings of the human eye are complex, but at the same time, fascinating. Have you wondered how exactly they do work or what are the major parts of the eyeball involved in creating vision? Let’s find out.

These tiny cameras spend every day processing millions of pieces of information at lightning fast speeds, and turn them into the simple images we see almost instantly.

In reality, this process is anything but simple. The eye has several distinct parts, each of which has specific responsibilities that work together like a machine.

The eyeball is just like a camera. In fact, human eyes are part of a classification known as “camera-type eyes.” And just like a camera, it can’t function without the presence of light.  As light hits the eyes, it’s focused by the eye in a way similar to a camera lens. This process allows the images we see to appear clear and sharp rather than blurry.

There are specific parts of the eye that make this focusing process possible. Each beam of light that hits the eye goes through a series of steps:

Step 1: Light passes through a thin layer of moisture

Step 2: Light hits the cornea.  The cornea is transparent, and is the first layer to begin focusing light within the eye. The cornea is connected to the sclera, which is a tough fiber on the outside of the eye that acts as protection.

Step 3: Behind the cornea is another liquid layer known as the aqueous humor, and its job is to maintain pressure levels in the front of the eye as light is passing through.

Step 4: Once light has passed through the aqueous humor, it has finally reached the pupil. The pupil is the round entryway of the colored iris.

Step 5: Once the pupil determines how much light it will let inside your eye, the job passes to the lens. The lens factors in the amount of light the pupil lets in, and figures out how far away you are from the object that the light is reflecting off of, or the object you’re trying to see. From there, the lens focuses your image into an accurate view of what you’re looking at. Part of this process is controlled by muscles in the lens called ciliary muscles, which expand and contract to pull on the lens and allow it to focus properly.

Step 6: As light reaches the center of the eye passes through another layer of moisture, called the vitreous, or vitreous humor. Then, it reaches the final stop in the process: The Retina.

The retina is the back of the eye. If the lens in your eye is most like a camera, the retina is most like its film – this is where the final product is projected. The retina has several parts:

  • Macula: The center of the retina. The center point of the macula is called the fovea, and it has the most photoreceptors and nerve endings of any part of the eye.
  • Photoreceptors: Split into two designations – rods and cones.
    • Cones are in the macula. When there is bright light, cones provide clear, sharp central vision and detect colors and fine details.
    • Rods are located outside the macula and extend all the way to the outer edge of the retina. They provide peripheral or side vision. Rods also allow the eyes to detect motion and help us see in dim light and at night.

  • Retinal pigment epithelium: Abbreviated RPE, this is a tissue layer below the rods and cones which absorbs any extra, unneeded light.
  • Choroid: The choroid is behind the retina, and is in charge of making sure the retina and RPE have enough nutrition flowing from small blood vessels.

Once the photoreceptors have converted light into an electronic signal, they send a signal to the brain’s visual command center and you have vision. It’s amazing what even small parts of our bodies can do.

 

How the Eye Works

January is Glaucoma Awareness Month

National Glaucoma Awareness Month reminds all of us to get regular eye exams and show support for those suffering from this condition.  Glaucoma is one of the leading causes of vision loss and blindness.  Glaucoma is often called “the sneak thief of sight” because glaucoma has few symptoms or warning signs in its early stages. It can be diagnosed only by a full eye exam by an eye care practitioner.

Glaucoma is a disease where pressure builds up and damages the eye’s optic nerve. Types of this disease include the common Primary Open Angle Glaucoma, which causes peripheral eyesight to slowly diminish and is age-related. Angle Closure Glaucoma, where the fluid drainage system is narrow and closed so that the aqueous fluid remains in the front chamber of the eye and intraocular pressure rises; and Low Tension Glaucoma, where the optic nerve becomes damaged in spite of the intraocular pressures being within the normal range. There’s currently no way to restore vision lost from glaucoma because once the nerve cells become damaged, they do not regenerate.

 

A few important facts you should know about Glaucoma in adults:

  • More patients than ever are affected – Over 3 million people in the U.S. have glaucoma, and the number is rising.
  • Glaucoma can affect people of all ages – The most common form of glaucoma, Primary Open Angle Glaucoma, becomes more prevalent with increasing age. However, glaucoma can strike anyone, even infants and children but it is rare.
  • Demographics do play a role – Glaucoma is a leading cause of blindness among African Americans; it’s also highly prevalent in Hispanics over the age 65.
  • Is glaucoma hereditary? The risk of developing Primary Open–Angle Glaucoma is up to nine times more likely if parents or siblings have the disease.
  • Hope for future glaucoma patients – Although there is no cure for any form of glaucoma, early diagnosis and treatment help control the disease and slow the process of vision loss or blindness.

Newer Glaucoma Treatments 

Glaucoma treatment usually begins with the use of topical (eye drop) medications which lower the intraocular pressure. Within the past two years, two new topical medications have been approved for the treatment of glaucoma: VYZULTA® and Rhopressa®. VYZULTA® is a modification of a class of medications currently used to treat glaucoma – the prostaglandin analogs. This drug helps lower intraocular pressure by increasing the drainage of fluid (aqueous humor) from the eye.

Rhopressa® is part of a new class of drugs used to treat glaucoma called Rho kinase inhibitors. Rhopressa®, like VYZULTA®, also lowers intraocular pressure by increasing aqueous outflow. Both Rhopressa® and VYZULTA® are dosed once daily and pose few, if any, systemic safety concerns.
 

Laser

Using a laser to make a small opening in the iris to help with fluid drainage usually cures Angle-Closure Glaucoma.  This procedure is called a laser peripheral iridotomy.

For Primary Open Angel Glaucoma, when eye drops are not enough to reduce the pressure then a procedure called Selective Laser Trabeculoplasty (SLT) can be used. The SLT reduces intraocular pressure by stimulating increased outflow of fluid from the eye. SLT offers an improved safety profile compared to older glaucoma laser therapies and may lower eye pressure by as much as 20 to 30 percent. It is typically used as the next step in patients whose glaucoma is uncontrolled on medical therapy. Because of its excellent benefit-to-risk profile, however, SLT can sometimes be used in place of medications, especially in patients who have difficulty with their eye drops.
 

Surgery

When other treatments fail, there are many surgical therapies to lower the eye pressure. These surgical approaches, which are riskier than medical therapy or lasers, are usually employed when non-surgical means do not work well enough to stop vision loss.
 

MIGS

The goal of Minimally Invasive Glaucoma Surgery (MIGS) is to reduce intraocular pressure by enhancing the eye’s own internal aqueous humor drainage system. Some MIGS can be performed as stand-alone procedures, while others are typically done along with cataract surgery in patients with visually significant cataracts and mild to moderate glaucoma.

There are now a variety of recently FDA approved MIGS available for use in this country. MIGS typically are performed through a small incision in the eye with minimal tissue trauma and offer a favorable safety profile as well as more rapid visual recovery than traditional glaucoma surgery. There are many well qualified glaucoma specialists that perform the MIGS procedure.

Low Vision

Low vision is the term used to describe significant visual impairment that can’t be corrected fully with glasses, contact lenses, medication or eye surgery.  Low vision causes a person to be unable to accomplish some daily tasks due to sight impairments. Low vision occurs when an individual struggles with any of the following common activities:

  • Reading
  • Everyday tasks like personal grooming
  • Viewing photos
  • Recognizing faces

Millions of Americans experience a normal loss of vision as they get older and the number of individuals who develop vision problems due to health conditions is projected to continue to rise.

There are many things that can cause low vision, including:

A few simple approaches can be:

  • Getting an eye exam
  • Update your reading glasses
  • Use bright light for reading

If these do not work for you, ask your eye care professional for help or ask for a referral to a low vision specialist.

Low Vision Technology 

Individuals with eye disease related to age, or vision compromised due to injury, may benefit from the usage of low vision devices.

There are two primary categories for low vision devices: Magnifiers for viewing things and objects that are close to you (magnifying lenses or machines), and magnifiers used for viewing objects and images at a distance (telescopic lenses). Many lighted magnifiers for close objects improve readability by increasing illumination.  With the advances in technology, many low vision devices are available to provide multiple function (near and distance) magnification and visual aid.

Technology is advancing to meet the growing needs of people with low vision impairment. There are a number of products that can help individuals with low vision. While considering the correct vision enhancer, keep in mind a few objectives:

  • What is the visual ability of the individual? Low vision aids are created with different options for specific low vision needs.
  • What tasks will the visual enhancer be used for? Find out what each product is best used for to decide if it will meet the needs of the individual.
  • Is the device easy to use? The right device should be easy for you to use.
  • How much does it cost? The cost of low vision aids can vary depending on a number of factors.

Popular products include:

Portable magnifiers and lighted magnifiers- offer magnified reading on the go. Perfect for menus, shopping lists, label reading, and more, portable magnifiers can fit in your pocket, purse, or be worn on the belt for quick, easy use.

 

Wearable magnifiers – wearable technology is the future for those with low vision who live an active lifestyle.  Wearable options make it possible to see and take part in everyday tasks, such as reading and recognizing faces.

 

Transportable magnification screens– are perfect for close up viewing as well as distance viewing. These great viewers offer great flexibility, from watching TV to using the mirror image feature for self-viewing. There are APPS for smart phones that can be used to magnify reading material.

  

Desktop devices for reading books, bills or letters – these have large, bright screens. A reading table offers visual aid for reading books, optional computer connectivity and more. This family of portable magnification units offers up to 75x magnification.

 

 

Consult a Low Vision Specialist–Consider making an appointment with a trained low vision specialist if you have specialized needs. They are available in larger cities or can be found by contacting The Braille Institute or by an internet search. Talk with your low vision specialist to find out which is right for you and where you can find them.

In addition to low vision devices and good lighting, inexpensive non-optical adaptive aids can assist with routine daily activities. These devices include:

  • Large-print cookbooks
  • Large-numbered playing cards, clocks, telephones and watches
  • Electronic “talking” clocks, kitchen timers, thermometers, blood pressure meters and even pill bottles
  • Large felt-tip pens and wide-lined paper for writing notes
  • Color-coded pill boxes
  • Signature guides help in writing your signature in the correct place

Many of these items can be found at your local drugstore, discount store or bookstore. Your low vision specialist can recommend retail sources for non-optical adaptive aids.

Vision loss can definitely be alarming but learning how to adapt, with the aid of low-vision specialists, can result in continued independence.  As low vision aids are tools focused on helping with the physical aspect, it is also important to seek the help of a counselor for psychological counseling if needed or join a support group, that may provide the help you need. Finally, maintaining a social network and asking for help will enrich your life, and help maintain your independence and quality of life.

Glaucoma – Are You At Risk?

January is Glaucoma Awareness Month and the perfect time to raise awareness for this disease. Early on there are no symptoms.  In fact, half of the people with glaucoma don’t even know they have it. Learn about glaucoma and the steps you can take to reduce your risk of vision loss.

There are several types of glaucoma, although the most common type of glaucoma is Primary Open-Angle Glaucoma, it begins at the peripheral working inward to weaken the central vision, this could lead to tunnel vision. It can cause irreversible and gradual damage of the optic nerve and vision.

You can prevent glaucoma with regular eye exams (with a visual field test) by an eye care professional and also by looking out for these subtle warning signs:

  1. Eye Pain
  2. Night Halos
  3. Tunnel Vision
  4. Blurred Vision
  5. Eye Swelling and Redness
  6. Nausea
  7. Sudden Visual Disturbance
  8. Severe Headache

Are you at risk?

Anyone can get glaucoma, but certain groups are at higher risk. These groups include African Americans over the age of 40, all people over the age of 60, and since it is hereditary, people with a family history of glaucoma, and people who have diabetes.

There are many steps you can take to help protect your eyes and lower your risk of vision loss from glaucoma. 

  1. If you are in a high-risk group, get a comprehensive dilated eye exam to catch glaucoma early and start treatment. Prescription eye drops can stop glaucoma from progressing.
  2. Even if you are not in a high-risk group, getting a comprehensive dilated eye exam by the age of 40 can help catch glaucoma and other eye diseases early.
  3. Open-angle glaucoma does not have symptoms and is hereditary, so talk to your family members about their vision health to help protect your eyes and theirs.
  4. Maintaining a healthy weight, controlling your blood pressure, being physically active and avoiding smoking will help you avoid vision loss from glaucoma.

Stay aware of the risks and symptoms and remember an annual comprehensive eye exam is key for early detection of glaucoma and other eye diseases.

My Best Gift!

The other day my daughter Blythe asked me which Christmas I consider to be my favorite.  I had to think a minute, because as a family, the Sullivan’s have had some great ones.  I was about to say the first time you and your brother Tom were old enough to really get into Santa, being absolutely sure that the fat man brought your presents right down the chimney.  I was about to say that, and then I remembered. 

The greatest Christmas I ever enjoyed was a ski trip in Winter Park, Colorado, when our children were teenagers and our friend, the marvelous Betty White, joined us for a Christmas Eve sleigh ride none of us will ever forget.  The night was perfect.  It had snowed earlier that day, and the air had a feeling of Christmas that you could almost taste.  Oh, sure, it was cold, but we were bundled up under tons of blankets as two beautiful Clydesdale horses with bells jingling took us through the woods to a magical barn where dinner would be served and carols sung. 

It was on the way home that my Christmas was made complete.  We had stopped to let the horses breathe, and everyone was quiet, just allowing the feeling of togetherness envelope us in that special night.  It was Betty who broke the silence. 

“Tom,” she said almost to herself, “I wish I may, I wish I might, let you see the stars tonight.  I feel like we could almost reach up and touch them.  That’s how bright and close they are.  I guess when you’re this high in the Rocky Mountains, it just feels like they’re right here.”

I could hear how much my friend wanted me to see such a heavenly display, but we both knew that could never happen.  I have no complaint about being blind, no one could have a better life, but I would be lying if I didn’t admit at this holiday season that I’d love to be able to take it all in, all the special sights of Christmas. 

Every day in laboratories around this country, researchers are working to solve the multiple eye diseases that make it impossible for millions of people to see the joys of Christmas.  At this holiday season, my best gift would be that all of us donate to the Discovery Eye Foundation with its goal to preserve vision and eradicate blindness around the world.  During this season of giving, may your hearts be light and your sight be bright. 

Merry Christmas!

I Can Only Imagine

I can only imagine my wife’s beautiful face.  Oh sure, I’ve touched it and kissed it many times.  I’ve felt the lines with the tips of my fingers, tracing our lives together, and I’ve heard her smile.  I understand that’s not really seeing it.  It’s not seeing her eyes as they sparkle with something funny I said; or, when she looks at me with love reserved only for those who are truly in love.

She’s often tried to explain the flash and colors of a sunset and the cotton softness of clouds as they drift across the sky.  And, what about a rainbow made up of all the colors that somehow promise all of us that things in the world will get better. 

How amazing it would be to see my daughter Blythe skiing her favorite Colorado Mountain trail or my son Tom riding a California wave, both so secure and happy enjoying the sports they love. 

There is so much more I wish I could see, but it’s not going to happen because I am blind.  I am left with only imagining what it’s like to have the gift of sight.

I can only empathize with how a person feels when their vision is threatened by glaucoma or diabetic retinopathy, retinitis pigmentosa, and the most devastating of all, macular degeneration.

At the Discovery Eye Foundation (DEF) our researchers are working every day to overcome the loss of vision and preserve your ability to treasure all the beauty that surrounds you.  I’ve heard it said that the eyes are the windows to the soul.  I don’t know if that’s true, but I am sure that they are the single most important sense in the group of five, and that saving vision is a cause that must be supported.

DEF is committed to that mission, and with your help, answers to all forms of eye disease will be discovered.  It’s up to all of us to support the research that’s bringing us ever closer to those solutions.

September is Healthy Aging Month

 

Today, people are living longer than ever before so it’s important to be proactive and take responsibility for your health as you age.  

Like any other organ in your body, your eyes do not stay the same as you get older. Vision changes are normal with age but vision loss and blindness are not.  Older adults are at higher risk for certain eye diseases and conditions, including age-related macular degeneration, cataract, diabetic retinopathy, glaucoma, dry eye, and low vision.  To continue to enjoy healthy vision as you advance in years, it’s important to have a comprehensive dilated eye examination with an ophthalmologist or optometrist on a regular basis.

Here are some other tips to maintain healthy vision now and as you age:

  • Eat a healthy, balanced diet. Fruits and vegetables can help keep your eyes healthy. Visit our website for healthy eye recipes, click here Eye Cook.

 

 

  • Maintain a healthy weight. Being overweight increases your risk for diabetes. By exercising regularly, you can help keep your body healthy and prevent vision loss. 

 

 

 

  • Don’t smoke. Smoking increases your risk for age-related macular degeneration, cataract, and other eye diseases and conditions that can damage the optic nerve.

 

 

 

  • Wear protective eyewear when outdoors. Protecting your eyes from the sun’s ultraviolet rays when you are outdoors is vital for your eye health.  Wearing sunglasses that block 99 to 100 percent of both UV-A and UV-B radiation.

 

 

  • Know your family history.  Talk to your family members about their eye health history. It’s important to know if anyone has been diagnosed with a disease or condition since many are hereditary, such as glaucoma, macular degeneration, and diabetes . This will help determine if you are at higher risk for developing an eye disease or condition.

 

  • Consider a multivitamin. Vitamins C, E and the mineral zinc have been shown to promote eye health.  Vitamins with Lutein and Zeaxanthin have been known to help patients with moderate to severe age-related macular degeneration.

 

  • Give your eyes a rest.  If you spend a lot of time at the computer or focusing at any one distance, you sometimes forget to blink, resulting in dryness and eye fatigue.  Every 20 minutes, look away about 20 feet in front of you for 20 seconds. This can help reduce eyestrain. Consider using a lubricant eye drop during long periods of intense eye use and rest your eyes for 5 minutes.

 

You can’t stop time, but you can take care of your eyes so that they remain healthy as you age. Having a healthy vision can be possible at any age! 

A New Commitment to Vision

Meet Tom Sullivan – DEF’s Ambassador of Vision

Over the last 40 years, I’ve been committed to working on behalf of blind children and their families.  My involvement has spanned the entire gamut of participation – from direct involvement in the classroom and counseling parents to hosting organized 10K races and celebrity golf tournaments that carried my name.  In that time, my wife and I raised just over $8 million thanks to the generosity of so many people.  Though my commitment to this cause has not changed, I’ve chosen to take on a new challenge that has in every way re-energized my passion. 

I’ve recently become the Ambassador of Vision for the Discovery Eye Foundation (DEF), a remarkable organization that funds cutting edge research that I believe someday will eliminate many forms of blindness.  The principle reason for my enthusiastic commitment is largely due to the fact that DEF directly funds researchers and avoids institutional restrictions.

As of this blog, DEF is engaged in ongoing efforts to understand 5 main eye diseases – Retinitis Pigmentosa, Macular Degeneration, Keratoconus, Diabetic Retinopathy, and Glaucoma.  I can honestly tell you that breakthroughs are not only on the horizon, but in many cases they are imminent.  Over the weeks and months I’ll be telling you much more, specifically about our individual research projects.  

Any help you may choose to give on behalf of people struggling with vision loss will be deeply appreciated. I look forward to having many of you join my fight for sight. Your help can make a difference! Click here to donate.

National Glaucoma Awareness Month

January is National Glaucoma Awareness Month –                                    An important time to raise awareness for this sight-robbing disease.

Glaucoma is an age-related disease and is the second leading cause of irreversible blindness in people over 40. Glaucoma is 6 to 8 times more common in African Americans than Caucasians. If you have a close blood relative with glaucoma, it raises your risk of getting it.

Glaucoma is the sneak thief of sight, since there are no symptoms and once vision is lost, it’s permanent. As much as 40% of vision can be lost without a person noticing. 

More than 3 million people in the United States and over 60 million people worldwide, have glaucoma. Experts estimate that half of them don’t know they have it. Combined with our aging population, we can see an epidemic of blindness looming if we don’t raise awareness about the importance of regular eye examinations to preserve vision.

How to Help Raise Awareness

In the United States, approximately 120,000 are blind from glaucoma. Here are three ways you can help raise awareness:

talk to your family about glaucoma awareness
Talk to your friends and family
  • Talk to friends and family about glaucoma. Do not keep it a secret. Let your family members know.
  • Get involved in your community, educational seminars, support groups, and more.

 

What is Glaucoma?

Glaucoma is a disease that causes damage to the major nerve of the eye called the opdevelopment of glaucomatic nerve, a part of the central nervous system that carries visual information from the eye to the brain.

The eye experiences a gradual increase of intraocular pressure (IOP) due to an imbalance of the fluid produced in the eye and the amount of fluid drained. Over time, elevated IOP can cause vision loss. The most common form of glaucoma is primary open angle glaucoma which affects about 3 million Americans. However, there are other types including narrow angle, congenital, normal tension, and secondary glaucoma.

There is no cure for glaucoma—yet. However, medication or surgery can slow or prevent further vision loss. The appropriate treatment depends upon the type of glaucoma among other factors. Early detection is vital to stopping the progress of the disease.

 

Risk Factors

How do you know if you are at risk for glaucoma? Those at higher risk include people of African, Asian, and Hispanic descent. Other high-risk groups include: people over 60, family members of those already diagnosed, diabetics, and people who are severely nearsighted.

Regular eye exams are especially important for those at higher risk for glaucoma, and may help to prevent unnecessary vision loss. In the most common form, there are virtually no symptoms. Vision loss begins with peripheral or side vision, so if you have glaucoma, you may not notice anything until significant vision is lost.

 

Getting your eyes checked by an ophthalmologist regularly will be the best way to detect glaucoma or any other eye disease early.
