​Macular Degeneration: Photo Dynamic Therapy (PDT)

This short video shows the PDT procedure for treating wet AMD which has developed close to or underneath the center of the macula.

While there is no cure for wet age-related macular degeneration (AMD), patients do have treatment options that may prevent, or halt the progression of the disease. Wet AMD develops in areas close to or underneath the center of the macula. For some patients, one type of treatment option is Photo Dynamic Therapy or PDT. During PDT, a laser is focused through the eye and onto the retina. The laser comes in contact with a special dye that is injected into the bloodstream, which then reacts, sealing the abnormal blood vessels to prevent further damage to the eye. The major advantage of PDT is that the laser uses no heat. This minimizes damage to surrounding tissue, allowing the procedure to be repeated multiple times if necessary. PDT rarely has any side effects, but it is important to avoid direct sunlight for several days following treatment. There is a chance that abnormal blood vessels can grow back and may require additional laser treatments. PDT is not a cure for macular degeneration. After treatment, it is important to check one’s vision regularly using an at-home test and to make regular visits to the doctor for follow-up care.
