PDT (Photodynamic Therapy)

Photodynamic Laser Treatment (PDT) and Visudyne Photodynamic laser treatment (PDT) is an exciting treatment approach that offers hope in the battle against visual loss from macular degeneration. PDT is an advanced laser technique used to seal leaks at the center of the macula without damaging the central vision. Photodynamic laser treatment (PDT) involves administering and an IV medication before the laser treatment is performed, which super-sensitizes the leaking vessels to the laser beam. This allows the use of a very low energy laser, which seals the leak but leaves the overlying retinal cells intact.

The FDA approved the first photodynamic intravenous drug, Visudyne. This treatment appears to be very safe. Only people with active leakage under the retina—the “wet” form—are candidates for this treatment. The leaks must be very active and “well defined ” and cannot exceed a armamentarium since FDA approval in 2000. Today, with newer macular degenerative treatments, this treatment is often used in combination with new treatments as part of combination therapy.

We also use this therapy for choroidal hemangiomas (tumors) and at “reduced fluency” for central serous chorioretinopathy (CSR).
