Does daily use of bright lights (10,000 lux) increase the risk of macular degeneration? These lights are used for circadian rhythm sleep disorders (CSRD) and seasonal affective disorder (SAD). UV is filtered out, but the lights are typically full-spectrum otherwise. [ 08/04/11 ]
The relationship between light and age-related macular degeneration (ARMD) is not fully understood. It is known that ultraviolet and blue light (short wave length visible light) can cause damaging oxidative stress to the retinal pigment epithelium (RPE). The RPE is the same layer of the eye where some of the pathological changes occur in patients who have ARMD. It may be prudent for ARMD patients to talk with their eye doctor if they are undergoing bright light therapy for various disorders.
One month after epiretinal membrane surgery I developed a cataract in that eye. If I delay the cataract surgery for one year, will it have an impact on the chances of a full recovery? [ 08/03/11 ]
Delaying cataract surgery for one year should not substantially impact the prognosis of surgery. Waiting for an extended period of time can allow the cataract to become very hard and dense, and increase the rate of surgical complications, however. After retinal surgery, such as epiretinal membrane surgery, cataract formation is more common. However, cataract surgery is typically performed for 6 - 12 months after the retina surgery to give the eye a chance to fully heal.
I am 87 years old. My doctor says that I have dry macular degeneration in my left eye and the wet form in my right eye. I received an Avastin shot about two weeks ago and now I don't see true colors. Many objects now appear pink. Is this an expected result? [ 08/02/11 ]
Color vision loss is not a commonly encountered side effect of Avastin intravitreal injections. Please schedule an evaluation with your retina specialist to discuss the color wash out that you are noticing.
I have been diagnosed with retina puckering or retina wrinkling. Are there any effective treatments? [ 08/01/11 ]
The treatment for retinal pucker or wrinkling is surgical removal of the membrane causing the puckering. This surgery is not performed unless the retinal puckering is causing a bothersome blur or distortion. The surgery is generally very effective; however, any eye surgery has the risk of bleeding, infection, and permanent vision do loss. No eye drops, oral medications, or laser treatments are currently available for the treatment of retinal puckering.
My 86-year-old mother recently underwent hip repair surgery, and she has had macular degeneration for at least 20 years. She states that her vision has worsened since the hip surgery, so I was curious if there was any connection between anesthesia and worsening of her vision? [ 07/31/11 ]
Blurred vision has been reported as a side effect of several types of general anesthesia. Some of this post-anesthesia decrease in vision is very transient; however, other surgery-associated vision loss can be more permanent. If this blurred vision persists, it would be prudent to have a full evaluation by an ophthalmologist. No link has been established between general anesthesia and worsening of age-related macular degeneration.
Is it true that the Avastin injections that also include steroids are more effective than Avastin alone? Is Avastin approved by the FDA for the treatment of macular edema? [ 07/30/11 ]
Avastin injections do not include any steroid medications and it has not been FDA approved for macular edema. However, Avastin has been used in an off-label fashion in thousands of patients worldwide suffering from a variety of eye disorders, including macular edema. Research is currently ongoing to test the efficacy of Avastin in combination with other therapies such as steroids or laser for a variety of diseases.
Is there any connection between myasthenia gravis and macular degeneration? [ 07/29/11 ]
No formal relationship has been established between myasthenia gravis and age-related macular degeneration (ARMD). Myasthenia gravis is thought to be an autoimmune disorder, which does not appear to be the case for ARMD.
I am 85 years old and have wet macular degeneration in the right eye. I have had three shots in the eye thus far, and during my most recent office visit, the nurse hit a vein while administering the anesthetic to my eye. My eye has been bloodshot for five days so far. It appears as though that eye is not fully open and may be paralyzed. Does this accident happen often and will my eye return to normal? [ 07/06/11 ]
It is not uncommon to have bloodshot eyes after eye injection for age-related macular degeneration. If you are not on blood thinners, the eyes will typically return to the normal appearance after 1 – 2 weeks. If you cannot move your eye or develop double vision, you should return to your retinal specialist promptly as eye muscle paralysis is not normal after an injection.
