What is Visudyne™ Photodynamic Therapy?
Visudyne™ Photodynamic Therapy can be used to treat macular degeneration as well as diabetic retinopathy.
In photodynamic therapy, a light-activated drug (Visudyne™) is injected into a patient’s bloodstream. Once the drug reaches the retina, it is activated by a non-thermal laser (A laser that does not burn). This produces a blood clot that closes abnormal vessels without causing damage to the retina. Abnormal blood vessels may return. However, Visudyne™ therapy can be reapplied at 3 month intervals.
