Latest Questions and Answers
Will scuba diving negatively affect age-related dry macular degeneration? I would love to engage in this sport again but not at a cost to my vision. [ 06/17/13 ]

No study has definitely linked a progression of dry age-related macular degeneration to scuba diving. You may want to check with your eye specialist to confirm that you have adequate clarity of vision to scuba dive safely, however.


I have read that some forms of protein are bad for the eyes. I eat lots of high protein Greek yogurt. Will that harm my eyes? [ 06/17/13 ]

An overabundance of protein can cause dry eyes, but rarely. Dry eyes can lead to serious complications such as infection and corneal perforation, but again, these serious complications are extremely uncommon. If you notice that your eyes feel very dry since your high protein diet began, you may want to talk with your doctor about using over the counter artificial tears, or reducing your protein intake.


I took Avastin injections for two years; I then developed a detached retina and needed surgery. Could Avastin have caused this detachment? [ 06/17/13 ]

Avastin itself does not cause retinal detachment. However, any injection into the vitreous cavity of the eye can cause retinal detachment in extremely rare circumstances. Specifically, any injection into the vitreous cavity can cause separation of the vitreous from the retina. When the vitreous separates from the retina, a retinal tear or detachment can occur very rarely. In most trials the rate or retinal tear or detachment after repeated intravitreal injection is less than 2 percent. Importantly, not all retinal tears lead to retinal detachment if detected and treated early. In general the injection procedure into the vitreous cavity is regarded as very safe, and literally millions of these injections are safely performed worldwide yearly.


I have age-related macular degeneration in both eyes and I have been diagnosed with clear fluid in the retina of my right eye. Are any of the commonly used treatments known to be particularly effective for these conditions? [ 06/17/13 ]

The source of the clear fluid in the right retina will dictate the best treatment. If you have wet age-related macular degeneration (ARMD) and have developed fluid in the retina from new blood vessel growth called choroidal neovascularization, the most effective current treatment is injection of medicine directly into the vitreous cavity. These medicines include Avastin, Eylea, or Lucentis. These medicines have been shown to prevent vision loss in 90% of patients who receive monthly injections, and your retina specialist will help determine which injection is best for you. Many other factors can cause fluid to build up in the retina including inflammation, recent surgery, diabetes, blood vessel occlusion, etc. If your retina fluid is from another cause, treatment should be directed against that cause.


I have macular degeneration and I experience a sensation that I have something in my eye. What does this sensation mean? [ 06/17/13 ]

Age related macular degeneration (ARMD) is a disease of the retina. ARMD is first noticed as blurred central vision, and a sensation that something in your eye is not usually related to this eye disease. Your sensation of having something in your eye can be from a variety of causes including dry eye syndrome or an actual foreign body in the eye. Please visit your eye care specialist and describe your symptoms. An examination should be able to reveal the source of your foreign body sensation in a relatively straightforward manner.


I was having trouble with my vision and I had never used glasses before. I went to an eye doctor and he saw something wrong with my eyes. Subsequently, a specialist diagnosed me with macular degeneration. The eye doctor then gave me glasses to see clearly and they do help with near vision; however, they don't to see objects in the distance. Is there anything I can do to get glasses that will help me with this issue? Any advice you can give me will be greatly appreciated. [ 05/17/13 ]

Glasses can help you see clearly at multiple different distances, but the glasses must be measured and made correctly to an exact set of specifications. If you are not satisfied with the clarity of vision your glasses at all distances, you need to see the prescribing doctor so he or she can recheck the measurements for the glasses. Age-related macular degeneration (ARMD) typically causes blurring of central vision at every distance; therefore, if you have good vision at close range, the ARMD is unlikely to be the cause of the worse distance vision.


My 85 year-old-mother has end-stage wet age-related macular degeneration. I am 59 and was just diagnosed with the dry form of this eye disease in my right eye and I have drusen in left eye. We both are diagnosed with hypothyroidism and take medication. Is there any correlation detected between hypothyroidism, the medications taken for this disease, and age-related macular degeneration? [ 05/17/13 ]

No definitive link has been established between hypothyroidism and age-related macular degeneration (ARMD). A few studies support a weak association between hypothyroidism and ARMD, and many others do not. Likewise, hypothyroidism is not known to definitely hasten progression of any type of ARMD. Similarly, most studies do not report a link between ARMD and medications for hypothyroidism.


My mother has had macular degeneration since 1994 (some physicians say that it is macular dystrophy). Her blind spot had a grayish-yellow color, and recently she saw colors such as pink and green covering her blind spot. We went to see a specialist, and they said her veins are swollen at the back of her eye. They could not explain why she sees all these colors. Also, my mom started regularly taking fish oil and drinking vegetable smoothies that were very high in vitamin A right before these colors appeared. What might cause my mom to see these colors? [ 05/17/13 ]

Changes in the retina or any other changes in the eye causing longstanding vision loss can cause the brain to perceive unusual colors or shapes. While this phenomenon has been described in the scientific literature, it is not known why the abnormal color perception occurs. Fish oil or vitamin A supplementation has not been linked to abnormal color perception. Finally, retinal vein swelling does not typically cause a change in color vision.
