About Macular Degeneration
Age-related macular degeneration involves changes to the macula, or central part of the retina, inside the eye. These changes gradually lead to vision distortion and vision loss, which cannot usually be reversed.
Age-related macular degeneration comes in two forms:
The dry form of macular degeneration involves the formation of drusen (small yellowish deposits) on the macula. This drusen causes distortions in your vision, and over time can lead to central vision loss.
The wet form of macular degeneration involves abnormal blood vessel growth in the macula. This abnormal blood vessel growth eventually leads to scar tissue forming, which can cause blind spots or central vision loss.
The wet form of macular degeneration is much less common, but much more serious, than the dry form.
Risk Factors for Macular Degeneration
- Age (over age 60)
- High Blood Pressure
- High Cholesterol
Testing for Macular Degeneration
Dr. Davis can detect macular degeneration during your regular eye health exam. The presence of drusen and abnormal blood vessel growth on the macula can be observed by looking at the retina. Other tests may reveal distortions in your vision that are also signs of macular degeneration.
There are several treatments that may slow the progression of macular degeneration.
Some drugs block the growth of abnormal blood vessels, and may even restore some vision lost to macular degeneration. These drugs are used in the treatment of wet macular degeneration.
Certain vitamins may help prevent macular degeneration. Ask Dr. Davis for current recommendations based on the latest studies.
Laser surgery can be used to stop the growth of, or even destroy abnormal blood vessels in the retina.
