These treatments include: Photodynamic therapy with Visudyne™. With this treatment, you receive Visudyne dye through an IV. A retina specialist then administers a low-energy laser (sometimes referred to as a “cold laser”) to the area of the wet AMD to activate the Visudyne medication. Patients receiving this treatment must avoid sunlight and bright halogen lights for five days after the treatment to avoid the risk of serious sunburn.
