Theater Company Gives Blind Actors Confidence

7/3/14

In this two-part blog post, you will learn more about an amazing program at CRE Outreach, which uses theater to engage and improve confidence among the blind participants, which is how the program started, later helping at-risk youth and military veterans. In the second post on Tuesday, one of the blind actors, Caitlin, will share her experiences as a member of the CRE Outreach troop and what it has meant to her.
theater - blind actors
When twelve visually impaired kids, ranging in age from eight to thirteen, are busy creating characters for their original play, silence is a rarity. Here, in the safe space of an acting class where everyone is visually impaired. I glance around the circle to see whose turn it is to suggest a character … and then I understand the silence. Eric is ten years old, totally blind, and autistic. He’s almost completely nonverbal. If he has ideas, which I often sense that he does, we never hear them.

It’s highly unlikely that Eric’s going to speak, or share, or rise from his hunched, self-protective crouch among the other students. I prompt him anyway. “Eric, it’s your turn. Do you have an idea for a character?”

Without warning, he lights up. A burst of energy seems to lift him right out of his hunched position, and with more clarity and volume than I’ve ever heard from him before, he declares, “I want to be a human telephone!”

Eric went on to be the lead in our show and now interacts socially with other kids. Acting has helped him build up his confidence and find his voice. And he isn’t alone.

CRE Outreach aims to transform lives one show at a time. From inception to performance, these actors play a major role in all aspects of the production. Inclusivity is the cornerstone of CRE Outreach. Our productions are based on authentic stories and rarely-heard messages, conveyed by the very people who should be sharing them.

CRE Outreach works with three different populations–at-risk youth, military veterans, and the visually impaired–using theater as an empowerment tool. For all participants, stepping into another character allows them to forget about themselves for a while. They feel new emotions, take on new experiences, and live a life which they don’t have the opportunity to live every day.

For blind actors, visual impairment is their common thread, but it’s their will to define their disability which truly binds them. To cement that bond, we introduce each new blind actor to our theater group with an exercise called “The Run.” One by one, each visually impaired actor races from one side of the stage to the other: an experience that they have never had before. Learning to use sound cues, along with textured mats on the floor, the actors break through their fears of movement and learn to navigate the stage independently. They learn to trust themselves and each other. As they run, they realize that the unknown isn’t half as scary as you’d think, when you have a family all around you.

Breathing, Patience and Keratoconus

7/1/14

Besides hearing from eye care professionals and Discovery Eye Foundation staff, we also think it is important to hear from people with sight threatening eye diseases such as age-related macular degeneration, keratoconus, retinitis pigmentosa, etc. They can share their experiences with others that are newly diagnosed with eye disease, while providing insights to family members, friends and caregivers. What follows is the first of these occasional posts focusing on the experiences and insights gained from vision loss.

“The expression on my optometrist’s face was as if he was giving me a cancer sentence,” Jeanette Hasseman remembers. “I had never heard of keratoconus, but he told me it was an incurable vision disability. He said he was aware of some evolving technology, but he wanted to give me some time to absorb and research the disease.
Jeanette Hasseman - keratoconus
“When I went back three months later, he told me a about a cross-linking study that was going on not-too-far from here, but I hadn’t fully absorbed all the information I was reading yet,” she recalls. I did not understand — even though it was plainly stated in the information I was looking at — that once you lose some vision, you don’t get it back.

“I kept thinking, ‘OK, this certainly can be fixed,” so instead of getting cross-linking in July, I waited until December. I regret not acting on my doctor’s suggestion of getting in the study in July, because I lost a tremendous amount of vision by December.”

Hasseman was tested and qualified for the clinical trial in December and had epi-on cross-linking in both eyes in January 2013. “The topography scans show the KC progression has been halted,” she says. “I rejoice in that.”

While her vision seemed better shortly after the procedures, she was diagnosed one week after crosslinking with a “gouge” (4 mm corneal abrasion) in her left cornea that resulted in severe hazing. While the severity of the corneal hazing has decreased in the past year, she is waiting to find out if it is permanent. If so, she may need to have a corneal transplant at some point to restore any visual acuity.

A registered nurse, Hasseman finished her BSN degree two years ago at age 54 — just months before she was diagnosed with KC. The native Ohioan has since stopped working as a nurse, and more recently, she had to give up teaching and doing tatting — lace-making — a hobby she had enjoyed for decades.

Hasseman found the National Keratoconus Foundation (NKCF) when she first Googled “kerotoconus.” “KC-Link has been a great blessing,” she says. “I’ve downloaded information; I signed up for KC-Link and asked questions of Catherine [Warren, director of NKCF] and the moderating doctors. I found great support for my own spirit, as well as information on the latest technologies.

“When people ask questions on KC-Link, if I can relate, I answer. Just the other day, someone who was just diagnosed asked, ‘Well, what should I do?’ I wrote: ‘First thing is: Breathe. Second thing is: Ask for information from your eye doctor and ask who is the best corneal specialist in your area who is really good for keratoconus. Most of all: Be patient.’

“It’s really hard to lose your vision. Even in your own heart, you can feel isolated. KC-Link gives you a body of other people who totally understand what you’re thinking, what you’re feeling, what frustrates you. There is so much advice you can get on KC-Link regarding contacts, how to keep eyes moist, how to handle low-light driving, what type of e-reader works best for people with keratoconus — you cannot exhaust the information that is shared; you cannot exhaust the different emotions that are shared.”

Food for Thought . . .

6/26/14

Can dinner really be delicious medicine for our eyes?

Recent studies have shown compelling evidence that specific nutrients support eye health.* When a vitamin or mineral is given as a supplement, are there the supporting micronutrients and enzymes required for optimal utilization of that supplement by our bodies? Is a nutrient more bioavailable and/or more beneficial to our health as a foodstuff than as a supplement? Are there unintended effects from supplements that are not present when the nutrient is derived from a food source?**

Visionary Kitchen - nutrients
Despite the many thought provoking questions, I personally take supplements as I feel it is difficult to acquire the nutrients strictly through food. Dietary preferences and requirements influence our everyday food choices as well as the quality of food available at our local grocery stores. Thoughtfully designed, well-sourced supplements have been shown to enhance eye health and general well being.
Here are some key nutritional principles which should be kept in mind to maximize the nutrient availability to our eyes and bodies from the foods that we eat:

1. Bioavailability: Vitamins A, D, E and K are fat soluble; the vitamin B-complex and vitamin C are water soluble. Dietary fats aid in the transport of fat soluble vitamins. Of particular importance to eye health are the fat soluble carotenoids in the vitamin A family, lutein and zeaxanthin. Carotenoids are the red, orange and yellow pigments found in fruit and vegetables such as kale, spinach, corn, apricots and orange bell peppers. To maximize their nutritional benefit, combine foods rich in carotenoids with a healthy source of fat such as olive oil, avocados or walnuts. Egg yolk contains the most bioavailable source of lutein and zeaxanthin and is preferentially deposited in the macula.

2. Nutrient Synergy: Nutrient synergy is the interaction of two or more nutrients that work together to achieve a greater effect than a single nutrient alone could. Foods have a vast array of micronutrients. We know that spinach contains a high level of lutein; however, we don’t know precisely how all the nutrients in spinach work together to promote eye health. Epidemiological studies show people who eat spinach have a lower risk for developing Age-related Macular Degeneration (AMD). Levels of lutein and zeaxanthin in the macula can be measured and low levels are a predictor for the risk of developing AMD.

3. Growing and Feeding Practices: The growing and feeding practices of the agriculture industry affect the nutrient profile and nutrient density of our food. Grass-fed versus corn-based animal husbandry, and wild versus farm-raised fish, alters the fatty acid profile. The amount of omega-3 fatty acids found in eggs varies depending upon the chicken’s diet. Ketchup from organically grown tomatoes contains nearly 50% more lycopene than from conventionally grown tomatoes. Choose quality ingredients whenever possible.

4. Cooking Techniques: Steaming, sautéing or pureeing will break down the plant cell walls increasing the body’s access to the lutein found in dark leafy greens. Cooking tomatoes will increase the availability of lycopene. Heat, however, diminishes the amount of vitamin C present. To maximize lutein and vitamin C, consume both fresh and cooked vegetable sources. Excessive heat and lengthy cooking times diminish vitamin content (mineral content will remain intact, however).

5. Whole Foods: Whole foods have benefits such as soluble and insoluble fiber which help to regulate blood sugar. Foods high in fiber have been shown to decrease total cholesterol, triglycerides and VLDL levels. Fiber supports gut health which is integral to nutrient absorption.

6. Select Eye Nutrient Dense Foods: Studies have highlighted lutein+zeaxanthin, the omega-3 fatty acids balanced with omega-6 fatty acids, the vitamin A family, the antioxidant vitamins C and E, as well as the mineral zinc. There a number of other nutrients that play a role in eye health including B vitamins, selenium and other plant based antioxidants. Knowing the food sources of these important nutrients will help you to make better food choices for eye health.

How does this sound for dinner tonight? Grilled wild salmon on a bed of lightly sautéed spinach with caramelized onions!

My New Vision With A Telescope Implant

6/19/14

What it’s like to see with the CentraSight telescope implant

Like many people, I’ve set goals in my life, both professionally and personally and like being an active and engaged member of my community and my country. I love to teach: I taught history, geography and special education for years in Banning, California and now live in Moreno Valley, California, with my wife of 32 years, Kay. I love my country: I’m a proud veteran of both the Army Reserve and the Navy. And I love an open road. My wife and I traveled the country visiting historical monuments in our 32-foot RV. I guess I’ve got what you’d call a real zest for life. But, over the past twenty years, all the things I enjoyed doing in my life, even the simple day-to-day activities, started to decline because I was slowly losing my vision due to age-related macular degeneration. For example, six years ago, my wife took over all the driving because I couldn’t see well enough to drive safely.

Roy Kennedy - telescope implant

That was a real turning point for me. My wife had to help me so much because I just couldn’t see. I needed help shopping because I couldn’t read labels. I started to avoid social situations, like visiting with friends because I was embarrassed that I couldn’t recognize faces any longer. As you can imagine it was heartbreaking for both me and my wife.

But then my doctor told me about a treatment I wasn’t yet aware of called the telescope implant. The device is very small (smaller than a pea!), and it is implanted in one eye to restore vision. My doctor explained that it works like a real telescope in that it magnifies images, which reduces the effect of the blind spot on my straight-ahead vision. The other eye does not get an implant because you need to keep some peripheral vision to help with orientation and balance. This sounded like science fiction! But I wanted to see if it could help me and I decided to give it a try.

I worked with a great team of specialists, who were part of a treatment program called CentraSight. My retina doctor, cornea surgeon, low vision optometrist and a low vision occupational therapist all counseled me about what to expect from the outpatient procedure, particularly afterwards. For example, I learned there was a significant amount of occupational therapy required to adjust and become proficient at using my new vision. I also was warned that my sight would not be like it was in my youth. I wouldn’t be able to do everything I used to nor would I be able to see, differently, the minute I opened my eyes.

I had my surgery in early 2013. The cost for the telescope implant and visits associated with the treatment program were covered by Medicare, which was very helpful. Thinking back, I was nervous on surgery day, but afterwards, I was told by my occupational therapist that I was one of the quickest to recover from surgery. I give lots of credit to my OT folks as well as my wife who helped me with the exercises at home. The most amazing part is being able to see my wife’s face again for the first time in six years! I’ve regained the ability to do many everyday tasks, like reading, working on my computer and watching old Westerns on TV. My wife and I are even back to traveling the open road in our RV (which she drives)!

I would recommend people learn more about the telescope implant to see if it might help them, the way it helped me. There are CentraSight teams across the country. When you call 1-877-99-SIGHT or visit www.CentraSight.com a trained CentraSight information Specialist will point you to the team closest to your home and can even help schedule the appointments for you. The telescope isn’t for anyone, but it can make such a difference in your life. It certainly did in mine.

Corneal Donor’s Age Not Critical for Transplant Success

6/17/14

In the United States, more than 40,000 corneal transplants are performed each year with a high success rate in comparison to other types of organ transplants. According to the Eye Bank Association of America (EBAA), keratoconus was the leading cause of anterior lamellar keratoplasty (DALK/ALK partial thickness transplant) and was the fourth most common indication for penetrating keratoplasty surgery in 2012 (their last reporting period).
corneal transplant-original size
Advances in technology have led to increasingly successful outcomes for all who need corneal transplants. New long-term research of corneal transplant patients have shown that the age of corneal donors is no longer as important as once thought by eye health providers. According to a study funded by the National Institutes of Health, ten years after a transplant, a cornea from a 71-year-old donor is likely to remain as healthy as a cornea from a donor half that age.

The Cornea Donor Study (see www.ClinicalTrials.gov), funded by NIH’s National Eye Institute (NEI), was designed to compare graft survival rates for corneas from two donor age groups, aged 12-65 and aged 66-75. It was coordinated by the Jaeb Center for Health Research in Tampa, Fla., and involved 80 clinical sites across the United States. The study enrolled 1,090 people eligible for transplants, ages 40-80. Donor corneas were provided by 43 eye banks, and met the quality standards of the Eye Bank Association of America. The study found that 10-year success rates remained steady at 75 percent for corneal transplants from donors 34-71 years old. In the United States, three-fourths of cornea donors are within this age range, and one-third of donors are at the upper end of the range, from 61-70 years old.

Prior to this study, many surgeons would not accept corneas from donors over 65. Since the supply of young donor corneas is limited, these study results are encouraging for those who face a corneal transplant . The high level of success rates using corneas from older donors (over age 60) greatly increases the pool of donated corneas and corneal tissue available for transplant. In 2012, corneal donors under age 31 comprised less than 10 percent of the U.S. donor pool. “Our study supports continued expansion of the corneal donor pool beyond age 65,” said study co-chair Edward J. Holland, M.D., professor of ophthalmology at the University of Cincinnati and director of the Cornea Service at the Cincinnati Eye Institute. “We found that transplant success rates were similar across a broad range of donor ages.”

“Overall, the findings clearly demonstrate that most corneal transplants have remarkable longevity regardless of donor age,” said Mark Mannis, M.D., chair of ophthalmology at the University of California, Davis, and co-chair of the study. “The majority of patients continued to do well after 10 years, even those who received corneas from the oldest donors.”

What Are Floaters? | Causes and Treatment

6/12/14

Floaters can be anything seen in your vision that moves “to and fro” with your eye movement. The movement is not stationary compared to a blind spot which is fixed or stationary in your field of vision.

Example of floaters
Example of floaters
The key is that the position changes with eye movement. Size, shape, color, etc. don’t matter. Anything that moves in your vision is called a floater.

Remember, if you experience new floaters; please see an eye doctor for an examination.

Here are some common causes of floaters:

  • Posterior Vitreous Detachment (PVD)
  • Retinal Tears
  • Blood (Vitreous Hemorrhage) can be caused by;
  • Advanced Diabetic Retinopathy
  • Retinal Tears
  • Retinal Vascular Occlusions
  • Inflammation or Infection
  • Asteroid Hyalosis

Posterior Vitreous Detachment
A posterior vitreous detachment (PVD) is a common cause of floaters. A PVD occurs when the vitreous separates from the retinal surface. This is a normal event and will eventually occur in everyone. Retinal tears are more likely to occur right after a PVD has started.

The vitreous is usually a clear watery gel. As we age, enough of the proteins in the vitreous liquefy and degenerate. Eventually, there is a physical separation of the vitreous from the retina due to this liquefaction.

“Floaters” can develop due to opacities/haziness due to the aging gel which is no longer absolutely clear due to changes in the optical properties of the gel or the interface between the vitreous and water inside the eye.

Tears in the Retina
Retinal tears can cause floaters by either causing a small vitreous hemorrhage, or by dislodging cells into the vitreous which are normally located underneath the retina.

Vitreous Hemorrhage
Blood in the vitreous can also cause floaters. A so-called vitreous hemorrhage may result from either a retinal tear or advanced diabetic retinopathy. Occasionally, retinal vascular occlusions can also lead to bleeding in the vitreous.

Blood in the eye often absorbs, but only your doctor can determine the exact nature of the floaters and if they are associated with a retinal tear. It’s impossible for you to tell the cause of floaters without a proper dilated eye exam.

Inflammation
Certain types of inflammation or infection can cause significant floaters. Actually, these are white cells which migrate to the retina and vitreous and can be seen a floaters.

Asteroid Hyalosis
This is a common entity where lots of fine white opacities are suspended in the vitreous. In most cases, these are not noticed by the patient. Sometimes, however, the so-called asteroid bodies are so dense they prevent good examination of the retina. Other times, especially after a PVD, the asteroid bodies are noticed and patients may complain of floaters.

New Floaters: Evaluation
All new floaters must be examined by your eye doctor within 24-72 hours after occurring. Even if the floaters disappear in that time frame, you should be examined to look for a possible tear in the retina.

Again, you, the patient, can NOT tell the cause of the floaters or if you’ve sustained a retinal tears. Retinal tears can cause a retinal detachment – a potentially blinding problem.

Treatment of Floaters
There are no medicines or eye drops to treat floaters. Most doctors advise simply putting up with the floaters.

For patients who have chronic problems with floaters, I recommend a vitrectomy. A vitrectomy is an eye operation, performed by a retinal specialist. The operation is comparable to a cataract operation in terms of safety and possible complications.

There are a handful of doctors who perform Yag laser to break up floaters.

20 Facts About the Amazing Eye

6/10/14

We don’t often give our eyes as much thought as we should, that is until something goes wrong and our vision is affected. But when you learn more about eyes, you realize just how amazing they are. Here are a few facts you may enjoy:

1. Eyes began to develop 550 million years ago. The simplest eyes were patches of photoreceptor protein in single-celled animals.

2. Your eyes start to develop two weeks after you are conceived.
Brown eyes 6.10.14
3. The entire length of all the eyelashes shed by a human in their life is over 98 feet with each eye lash having a life span of about 5 months.

4. To protect our eyes they are positioned in a hollowed eye socket, while eyebrows prevent sweat dripping into your eyes and eyelashes keep dirt out of your eyes.

5. Your eyeballs stay the same size from birth to death, while your nose and ears continue to grow.

6. An eye is composed of more than 2 million working parts.

7. Only 1/6 of the human eyeball is exposed.

8. Corneas are the only tissues that don’t have blood.

9. The human eye weights approximately just under an ounce and is about an inch across.

10. An eye cannot be transplanted. More than 1 million nerve fibers connect each eye to the brain and currently we’re not able to reconstruct those connections.

11. 80% of our memories are determined by what we see.

12. Eyes heal quickly. With proper care, it takes only about 48 hours to repair a minor corneal scratch.

13. There are about 39 million people that are blind around the world.

14. 80% of vision problems worldwide are avoidable or even curable.

15. Humans and dogs are the only species known to seek visual cues from another individual’s eyes, and dogs only do this when interacting with humans.

16. A fingerprint has 40 unique characteristics, but an iris has 256, a reason retina scans are increasingly being used for security purposes.

17. People who are blind can see their dreams if they weren’t born blind.

18. “Red eye” occurs in photos because light from the flash bounces off the back of the eye. The choroid is located behind the retina and is rich in blood vessels, which make it appear red on film.

19. 80% of what we learn is through our eyes.

20. Eyes are the second most complex organ after the brain.

What You Need to Know About Cataracts

6/5/14

Do you feel like your vision is getting worse? Do you feel like colors are not as vibrant as they used to be? Are you having more trouble with glare? If you have any of these symptoms, you may be experiencing the effects of cataracts.

Cataracts are a normal aging process of the crystalline lens in the eye. Well you may ask — what is the crystalline lens? It is easiest to think of the eye as a camera. The eye has a lens (actually two) – the cornea (the front window of the eye) and the crystalline lens (inside the eye). It also has an aperture (the colored iris), and film (the retina). All these structures work together to focus light and allow us to see – just like a camera. When we are young (less than 40), the crystalline lens is flexible. This is why we are able to see distance and then near without the need for reading glasses. The crystalline lens is able to change its shape depending on where one is looking.

Figure 1 – Slit-lamp photo of a visually significant cataract.
Figure 1 – Slit-lamp photo of a visually significant cataract.

As we age, the crystalline lens becomes less flexible, thereby causing one’s near vision to be more blurry. This necessitates the need for reading glasses. As the crystalline lens become less flexible with age, the lens also starts to become more yellow and can also become cloudy. When the yellowing and/or clouding become visually significant, we refer to this as a cataract (figure 1).

Are cataracts dangerous? The simple answer is no. In the vast majority of cases, a cataract can be monitored until it becomes visually significant (drop in vision, glare, decreased contrast, vision related difficulties with day to day activities, etc). However, there are a few instances in which cataract removal is a medical necessity. Routine examinations by your eyecare provider can help you determine if you are at risk for these less common instances.

Figure 2 – Intraoperative photo during cataract surgery (prior to cataract removal).
Figure 2 – Intraoperative photo during cataract surgery (prior to cataract removal).

What can I expect during cataract surgery? Do you have to replace the crystalline lens with anything? Cataract surgery involves removing the clouded crystalline lens (figure 2) and replacing it with an artificial lens known as an intraocular lens (IOL) (figure 3). Surgery generally takes 10-15 minutes under a mild sedative, and you don’t have to stop any of your current medications. Anesthesia is achieved with drops and you will only feel mild pressure during the surgery. IOLs come in different styles – Standard IOLs grossly correct your vision and you can fine tune your vision (distance and near) with glasses post-operatively;

Figure 3 – Intraoperative photo during cataract surgery (after implantation of an IOL).
Figure 3 – Intraoperative photo during cataract surgery (after implantation of an IOL).

Toric (astigmatism correcting) IOLs allow for increased spectacle independence, but glasses will still be needed for distance or near; Accommodating IOLs “flex” within the eye to decrease your dependence on distance and near glasses; Multifocal IOLs allow spectacle independence for distance and near. I always counsel patients that there is no perfect IOL and you have to determine which IOL is best for your particular situation. Your doctor can help you decide which IOL is best for you. Generally, cataract surgery is extremely safe. Your doctor will discuss particular risks specific to your eye.

How do I know if cataract surgery is right for me? The best way to know if you have a cataract and if it time to consider surgery is to consult with your local ophthalmologist. If you have experienced a recent drop in vision, that is not correctable with glasses, cataract surgery may be able to restore your vision!

Little Bottle, Big Relief

What you need to know about eye drops.

Have you been staring at a computer all day and your eyes are tired? Have allergies been making your eyes watery and itchy? Are your contact lenses irritating your eyes? If you have experienced any of these conditions, you have probably turned to eye drops for relief.

While eye drops are an easy and effective means of treating a number of eye issues, there are many different eye drops available, both over the counter (OTC) and by prescription. It is wise to know what your underlying condition is before trying to get relief.
eye drops 6.3.14
If your eyes are red and you may want to try a decongestant eye drop, which will shrink the tiny blood vessels in the “whites” of your eyes (sclera), but they also cause dryness so may not be a good choice if you wear contact lenses.
For lens wearers you are better off with a re-wetting drop to lubricate the eye and lens making you more comfortable. Another problem with the decongestant eye drops is over use – which can cause irritation and an increased tolerance that could lead to more redness.

If you suffer from allergies and antihistamine eye drop would be the best choice for relief from itchy, watery, red and swollen eyes. They work by reducing histamine in the eye tissue.

Lubricating eye drops, also known as artificial tears, are for short-term relief caused by temporary situations such as eye strain form computer use, being tired or being outdoors in windy and/or sunny conditions. If the condition is chronic, a prescription eye drop will be the best choice.

It is important to remember that if any of the above symptoms worsen or continue for an extended period of time, it is time to see your eye doctor to determine the underlying cause of your issue and to rule out eye disease. Postponing a visit could also lead to an eye infection.

Prescription drops are used to treat a wide variety of eye diseases such as glaucoma, dry eye and the symptoms of ocular herpes. They are also used to help with healing from cataract surgery, corneal transplants, glaucoma surgery and even Lasik. it is extremely important to use them as often as your ophthalmologist recommends to improve healing and prevent infection.

Because of the ease of applying eye drops researchers are working toward using them to treat other eye diseases. Ocular herpes symptoms are sometimes treated with antiviral and steroid drops. But this only is targeted at the symptoms and not the underlying cause, the herpes simplex virus. Lbachir BenMohamed, PhD and Steven Wechsler, PhD at the University of California, Irvine, Gavin Herbert Eye Instittue have been working to determine what reactivate the herpes simplex virus and develop an eye drop that would either stop the reactivation of the virus or kill it.

Using eye drops to treat age-related macular degeneration (AMD) is also being explored. Researchers at the Institute of Ophthalmology at University College London are working with nanoparticles to deliver anti-VEGF drugs such as Lucentis and Avasitn to the back of the eye via drops. “The study shows that Avastin can be transported across the cells of the cornea into the back of the eye, where is stops blood vessels from leaking and forming new blood vessels, the basis for wet AMD.” While researchers in the Department of Ophthalmology, Tufts University School of Medicine in Boston “reported in their “proof of concept” study that topical application of a compound called PPADS inhibits damage to the tissues in the eye that impacts the individual’s ability to see color and fine detail, as well as reduces the growth of extraneous blood vessels in the back of the eye related to AMD.” It would work in both dry and wet AMD reduce the need for direct injections.

Eye drops, when properly applied, can provide temporary relief from symptoms of eye discomfort. But if the symptoms worsen or continue for an extended period of time, consult your eye doctor. To make sure you apply the eye drops correctly check out the article in our February 2013 newsletter for 12 easy steps to get the drops into your eyes and avoid infection.

One final note – keep your eye drops out of reach of children. Eye drops come in small bottles that are the perfect size for small hands and don’t have the same security tops found on other medications. The FDA has warned that ingredients found in some eye drops that relieve redness have caused abnormal heart rate, decreased breathing, sleepiness, vomiting and even comas in children five and younger that have ingested them. If you child has swallowed eye drops, call the Poison Help Line 800-222-1222.
