Full Answer

Macular degeneration is a disease that degrades the macula, which is the part of the retina that makes details appear sharp and vivid, notes MedlinePlus. The blood vessels that lead to the macula undergo damage, which affects the functionality of the macula. The disease may not cause any symptoms initially, but over time, central vision problems occur, including blurred vision; dim and distorted views of objects; and colors that appear faded. A blurred spot develops in the center of the field of vision and gets darker and larger as the disease progresses.

Doctors classify the disease in both dry and wet forms, with the dry form being most common, reports MedlinePlus. In dry macular degeneration, the blood vessels supplying the macula become brittle and thin, and deposits form on the macula. Wet macular degeneration involves the growth of abnormal blood vessels underneath the macula that leak fluid and blood. The most common symptom of wet macular degeneration is straight lines that appear wavy and distorted. Medical science does not know what causes macular degeneration. However, risk factors identified for the disease include a family history of macular degeneration, being a woman, eating a high-fat diet, being Caucasian and smoking.
