Macular Degeneration (Age-Related Type) (cont.)
What research is being done?
The National Eye Institute is conducting and supporting a number of studies
to learn more about AMD. For example, scientists are:
- Studying the possibility of transplanting healthy cells into a diseased
- Evaluating families with a history of AMD to understand genetic and
hereditary factors that may cause the disease.
- Looking at certain
anti-inflammatory treatments for the wet form of AMD.
This research should provide better ways to detect, treat, and prevent vision loss in people with
Macular Degeneration At A Glance
- 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
- Degeneration of the macula occurs most often after the age of 60
years and is termed age-related macular generation (AMD).
- Smoking increases the risk of AMD.
- AMD is a painless condition.
- There are two types of AMD: dry AMD and wet 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.
- Dry AMD cannot be treated at present.
- An early symptom of wet AMD is the wavy appearance of straight
- Early diagnosis of wet AMD is particularly critical; if in doubt,
go to the doctor.
- Laser surgery can save sight in wet AMD.
