Age-Related Macular Degeneration
The macula retinae, also called the macula lutea, is an oval disc on the retina in the back of the eye. Degeneration of the macula retinae is the leading cause of blindness in elderly Americans.
What are the symptoms of macular degeneration?
Macular degeneration is typically painless and includes symptoms of dark or blurry areas in the center of vision, seeing distortions of straight lines, and difficulty doing activities that require sharp vision (e.g., driving and reading). Peripheral (side) vision may remain clear.
How is it treated?
Eyeglasses with protection from the sun’s ultraviolet rays are often prescribed. Underlying medical conditions, such as diabetes and high blood pressure, are treated when present. In some cases, laser eye surgery may be recommended.
Dietary changes that may be helpful:
In a preliminary study, high intake of saturated fat and cholesterol was associated with an increased risk of developing macular degeneration.
According to preliminary research, people who eat fish more than once per week have half the risk of developing age-related macular degeneration compared with people who eat fish less than once per month.
