Macular degeneration facts
- The macula is in the center of the retina, the light-sensitive layer of tissue at the back of the eye. The macula is responsible for central vision (straight-ahead vision). Degeneration of the macula occurs most often after the age of 60 years and is termed age-related macular generation (AMD).
- AMD is a painless condition.
- There are two types of AMD: dry AMD and wet AMD.
- Smoking, high blood pressure, obesity, a diet high in unsaturated fats and simple carbohydrates and lack of exercise all increase the risk of AMD.
- Early symptoms of dry AMD include slightly blurred vision, the need for more light for reading, and difficulty recognizing faces until very close to the person. A symptom of more advanced dry AMD is the presence of a blurred spot in the center of vision. An early symptom of wet AMD is the wavy appearance of straight lines.
- Dry AMD cannot be treated at present, but progression can be slowed through a healthy lifestyle and, in certain cases, through anti-oxidant vitamins. Injections into the eye of anti-angiogenic agents are successfully used in arresting or slowing wet AMD. Because of new therapies for the wet form of AMD, early diagnosis of wet AMD is particularly critical.
