Fundus photographs of a patient who received prophylactic photocoagulation treatment for high risk drusen. (A) Before treatment with 12 spots ×200 µm ×0.2 seconds at a power to just whiten the retina. The lesions are placed in a ring 1000 µm from the fovea; (B) 3 months after photocoagulation; (C) 6 months after photocoagulation; (D) 20 months after photocoagulation. Note that the clearance starts around the area of the laser burns and spreads out circumferentially and that the effect is continuing at 20 months.
