Can prism lenses correct double vision caused by macular degeneration? [ 12/17/12 ]
Prism lenses can correct double vision caused by misalignment of the two eyes. Age-related macular degeneration (ARMD) typically does not cause eye misalignment, so prism lenses would not be helpful in most cases of double vision due to ARMD. If your double vision is present at any point when either eye is closed, it is unlikely that prism lenses will help.
I am a white 84-year-old male in fairly good health, but am borderline anemic and have macular degeneration in both eyes. Would taking iron infusions make my macular degeneration worse? [ 12/17/12 ]
No definite link has been established between iron infusions for anemia and age-related macular degeneration (ARMD). Very high levels of iron may be linked to a variety of retinal diseases due to increased oxidative stress in some patients, but this idea is a theory that is undergoing study. Oxidative stress occurs when the body cannot detoxify certain chemicals associated with metabolism of oxygen. If you have low levels of iron and are taking supplements to get back to normal levels of iron to treat anemia, the potential of oxidative stress toxicity is less likely.
My husband has been taking Lucentis injections for a year and he's not getting any better or worse. His doctor wants to try another treatment. Are there any other treatment alternatives? [ 12/17/12 ]
If your husband has wet age-related macular degeneration (ARMD), Lucentis is a very common treatment. In clinical trials, Lucentis preserved vision in 90% of patients, but improved vision in only 40% of patients with wet ARMD. Your husband many not belong to the 40% of patients that notices significant visual improvement after Lucentis treatment. Other commonly used treatments for ARMD include Eylea and Avastin, which have comparable treatment success rates to Lucentis. Some patients may react better to one eye injection compared to another. Ask your husband's retina specialist if a trial of one of these other wet ARMD injections would be appropriate.
Approximately five years ago I was diagnosed with dry macular degeneration. During a recent eye exam, the doctor informed me that I have developed wet macular degeneration in my left eye. My vision is limited and is very blurry. I am scheduled to receive a series of three injections. How long will the effects of the injections last and does it mean that the right eye will also develop the wet form of this disease? [ 12/17/12 ]
A minority of patients (about 10%) with dry-age related macular degeneration (ARMD) convert to wet ARMD and the most effective treatment for wet ARMD is an injection of a certain type of medication into the eye. In multiple clinical trials, these medications preserved vision in 90% of patients, but improved vision in only 40% of patients. People require different frequencies of treatment, and the most common dosing plan is monthly.
If the left eye has wet ARMD, the right eye is at higher risk of developing wet ARMD. The risk can be as high as 75% in the next five years depending on whether certain features were observed in the right eye during the examinations.
My 91-year-old mother-in-law has been receiving eye injections and she can basically just see light and dark. Should she have to continue to get the injections? Will her vision improve beyond what it is now? [ 12/17/12 ]
Intravitreal eye injections such as Lucentis, Avastin, and Eylea are the most effective treatments for wet age-related macular degeneration (ARMD). In multiple clinical trials, these injections preserved vision in 90 percent of patients, but improved vision in only 40 percent of patients. Your mother-in-law may be in the 90 percent of patients that that eye injections preserve vision in, but not in the 40 percent of patients that notice significant visual gain after injection. Your mother-in-law's vision may improve with continued injection, and the vision could decline if injections are stopped. Predicting these outcomes is very challenging and depends on a variety of factors. Please discuss the potential results of stopping or having less frequent injections with your retina specialist.
I am 63 years old and have macular degeneration. I recently had cataract surgery, and immediately the vision in my right eye became foggy; instead of seeing straight lines I perceived them as wavy. I had also had cataract surgery on the other eye and probably 90 percent of the time I can hardly open my eyes at when I am outdoors. My eyes are very sensitive. I wish I would have not had the surgery. The doctors never told me anything about this possibility and my life has changed so much. What else could happen to my eyes as a result of the surgeries? [ 12/17/12 ]
Your right eye could be blurry for a variety of reasons including things related to your cataract surgery and/or your age-related macular degeneration (ARMD). You may be light sensitive for a variety of reasons related to one or both processes as well. Without a complete eye exam and possible testing, it would be difficult to differentiate between the multiple things that could be causing your symptoms based on your description alone. You might also consider getting a second opinion from a retina specialist regarding the prognosis of your symptoms and what could be causing those symptoms.
I have wet age-related macular degeneration in one eye. How likely is it that the other eye be affected? [ 12/17/12 ]
If the one eye has wet age-related macular degeneration (ARMD) the other eye is at higher risk of developing wet ARMD. The risk can be as low as 10 percent and as high as 75 percent in the next five years depending on whether certain features were observed in the eye with dry ARMD. Speak to a retina specialist about your eye exam findings, what specific risk you have for developing wet ARMD, and if you would benefit from taking a formula of eye vitamins for patients with high risk dry ARMD. This vitamin formula has been shown to help prevent conversion of dry ARMD to wet ARMD in a certain subset of patients.
I have twice undergone chemotherapy for hepatitis C. The first treatment started to shut down my bone marrow and they discontinued it, and during the second treatment, a substance was added to the alpha-interferon, which I believe was called Rebetron or Reprotron. Soon after this second treatment I was soon diagnosed with diabetes and macular degeneration. There is no diabetes for any male on my father’s side of my family, and no one has had macular degeneration. I believe both treatments caused depression and vision problems. Is there evidence that these treatments can cause either diabetes or macular degeneration? Thank you. [ 12/17/12 ]
Rebotron is a combination treatment of ribavarin and interferon for the hepatitis C virus. No definitive link has been established concerning the use of these medications and developing or worsening of age-related macular degeneration (ARMD). Interferon can cause a variety of other changes in the eye however, so you should have a full examination by an ophthalmologist. Also, interferon has previously been associated with development of diabetes, so please discuss this with your medical doctor prescribing the Rebotron.
