Macular Degeneration or AMD, is a progressive condition that affects the central portion of the retina that provides the ability to perceive fine visual detail. This central portion is called the Macula and contains photoreceptor cells that convert light into electrical impulses for subsequent transfer to the visual cortex of the brain via the optic nerve. When these photoreceptors begin to deteriorate or fail - you have the beginnings of macular degeneration.
When macular degeneration begins to occur, you may first notice a blurring of central vision when performing visually detailed tasks such as reading and sewing. Blurred central vision may also make straight lines appear slightly distorted or warped. As the disease progresses, blind spots form within your central vision. In most cases, if one eye has macular degeneration, the other eye will also develop the disease.
Currently, there is no known way to prevent AMD. The most important defense is to have regular eye exams, particularly after you turn 50 and/or if macular degeneration runs in your family. There are several types of AMD (wet and dry) which we won't go into here.
Treatments for AMD are limited. A procedure known as photocoagulation may help by destroying blood vessels growing beneath the retina in order to seal leaky areas and slow or halt the spread of AMD. This procedure doesn't restore vision already lost - but does reduce the rate of loss. Again, as we've indicated before - regular eye checkups at our Newport Beach, CA clinic - that test for these conditions will spot potential AMD and allow your eye care physician to implement an appropriate course of action.
