Age-related macular degeneration, also referred to as AMD, is a common eye disease associated with aging that gradually impairs sharp, central vision. It affects approximately 13 million people in the U.S. and is the leading cause of severe vision loss in people over age 50. Up to 200,000 new cases of the neovascular or "wet" type of AMD are diagnosed each year in the U.S.


Photo Dynamic Therapy (PDT)

How the Process Works
Patients are injected with a light-sensitive drug that is absorbed in the damaged blood vessels. A special low-power laser light then is used for about a minute to trigger a chemical reaction that slows or halts the growth of those vessels without affecting the surrounding tissue. As a result, studies have shown that PDT improves vision in a few cases, its main benefit is arresting the progression of this sight-threatening condition.

After Treatment
Because of the light sensitivity caused by the injected medication, your skin and eyes will be sensitive to bright light for 24 to 48 hours after the treatment.

Follow-Up and Re-Treatment
The abnormal blood vessels may return after several months. However, PDT may be reapplied at up to 3 month intervals if necessary.
