Macular Degeneration
Macular degeneration is damage or breakdown of the macula. As the eye looks straight ahead, the macula is the point of the retina upon which the light rays meet as they are focused by the cornea and the lens of the eye. On a damaged macula, the central part of the images is blocked causing a blurred area in the center of the picture. However, the images around the blurred area may be clearly visible. Macular degeneration usually affects both eyes, but often begins in one eye.
The eye still sees objects to the side, since side or peripheral vision is usually unaffected. Because of this, macular degeneration alone does not result in total blindness. However, it can make reading or close work difficult or impossible without the help of special low vision optical aids.
Many patients do not realize they have a macular problem until blurred vision becomes obvious. An examination can detect macular degeneration in its early stages. The doctor will usually include a few more tests including a grid test, a color vision test and in some cases, a fluorescein angiogram is done. Early detection may prevent further damage to your eye(s).
There is no cure for macular degeneration. However, ophthalmologic laser surgery can be used to slow the disease by sealing off leaking membranes and destroying new blood vessels. This reduces further loss of vision from progressive scarring of the macula and the surrounding retina.
Low vision optical aids often improve vision for people with macular degeneration. Many different types of magnifying devices are available. With the variety of visual aids available today, people with visual loss can often read, do modified close-up work and continue to take care of themselves. Many patients lead a comfortable and relatively normal life.
Early detection is the key to the prevention of visual loss. The Eye Surgery Center of Arkansas has a staff of medical professionals that will provide quality care for your eyes. Contact us for information or to arrange an appointment for your eye examination.
