DHA and macular degeneration (I)

macular degeneration

Macular degeneration is a disease of the eye that gradually destroys the macula, the part of the retina (inner eye’s membrane that turns light and images into nerve signals that are sent to the brain) that allows us to see details clearly. It is often called age-related macular degeneration (AMD) because it is most common among people age 50 and older, of which it is a leading cause of vision loss in developing countries. It does not hurt, but has one typical symptom: to see dark areas in the central vision, without affecting the peripheral vision; for example, you could see the outline of a clock, but not its hands.

The progression of age-related macular degeneration can be slow or fast, but it does not cause complete blindness, because the peripheral vision remains intact. Even so, age-related macular degeneration makes it hard to read, work on the computer, sew, drive, recognize faces at a distance, etc.

Treatment can slow vision loss, but it does not restore it. So, prevention is crucial. A healthy diet is one of the factors that can reduce the risk of developing this disease and one omega-3, DHA, can help us, as will see in a next post.
