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.
NEW OPTIONS FOR THE TREATMENT OF WET
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
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
