Macular Degeneration

Macular degeneration is a disease that breaks down the macula, the light-sensitive part of the retina responsible for sharp, direct vision. Macular degeneration usually affects central vision. It is the leading cause of blindness in the United States, affecting to some extent an estimated 13 million Americans.

Most cases of macular degeneration are related to aging, with the majority of those afflicted over the age of 65. Because the disease is often associated with age, it is also referred to as age-related macular degeneration.

Macular degeneration runs in families, and women and whites are more likely to develop the disease than any other group. Other factors that contribute to a high risk of macular degeneration are smoking, high blood pressure, farsightedness and obesity. The condition may also be a side effect of certain medications.

Symptoms of macular degeneration may come on slowly or suddenly, often producing a painless loss of vision. Early signs of macular degeneration may also include wavy lines, blank spots and fuzzy or shadowy vision. A routine eye exam can determine signs of macular degeneration before they are even felt by the patient.

Macular degeneration is not reversible or preventable. However, recent research and advanced therapies have made living with macular degeneration more bearable. A new study reports that antioxidants, such as beta-carotene (vitamin A) and vitamins C and E may protect the macula from damage. These vitamins, in addition to zinc, have also been found to reduce risk of progression to advanced macular degeneration. Drug therapies and laser surgeries are also showing promise as future treatments for macular degeneration.
