Abstract
Multiple reports have documented the disappearance of soft drusen in age-related macular degeneration after laser photocoagulation.1-3We describe a patient with a deposit of a granular subfoveal material who suffered visual acuity loss following this treatment. To our knowledge, this is the first such complication reported for this form of therapy. Report of a Case. A 70-year-old Asian woman with bilateral pseudophakia who had a history of diabetes was initially seen with visual acuities of 20/125 OD and 20/25 OS. The right eye showed a largepigment epithelial tear with serous detachment of the macula caused by a large choroidal neovascular membrane. The left eye demonstrated many large, soft macular drusen with central confluence and mild subfoveal pigment clumping (Figure 1). Fluorescein angiography confirmed these findings. As part of a pilot study investigating the role of light laser treatment in stimulating drusen resorption and its safety, light laser burns were
