Macular Degeneration

 

The macula is the central portion of the retina that is responsible for our sharpest vision, allowing us to read fine print or perform intricate handwork like stitching or sewing.

As we age, the cells of the macula and retina begin to break down and can no longer send normal signals of light throught the optic nerve to the brain. The result is blurred vision, often an early sign of a condition known as macular degeneration.

The major cause of severe vision loss in people over 60 macular degeneration comes in two forms:

Dry form - In the mild dry form, aging spots appear in the macula and vision slowly deteriorates. The damage can vary greatly, however, because some people can have the condition for years and still have fairlly good vision.

Wet form - In the more severe wet form, abnormal blood cells grow under the retina and macula, a condition known as angiogenesis. As these blood vessels bleed or leak, central vision becomes distorted and vision loss is usually rapid and severe. Patients usually report a dark spot in their central line of vision and, because the macula is no longer smooth and straight, straight lines appear wavy.

Up until quite recently, there was little that could be done for the majority of patients with for the most severe form of macular degeneration. New drugs, however, are now available that check the growth of abnormal blood vessels and can actually reverse the effects of macular degeneration.

These new drugs, usually injected directly into the eye, include Lucentis (ranibizumab), Avastin (bevacizumab) and Macugen (pegaptanib).
