Multiple reports have documented the disappearance of soft drusen in age-related macular degeneration after laser photocoagulation.1-3 We 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
