The authors report spectral-domain optical coherence tomography findings of laser pointer-induced maculopathy in a 25-year-old man after accidental laser pointer exposure of less than 1 second. The Class 3R laser pointer (output wavelength 532 nm and output power 3.5 to 4.5 mW [continuous wave]) had U.S. Food and Drug Administration certification. One day after exposure, he had visual blurring and metamorphopsia of his right eye. He was treated with a systemic high-dose corticosteroid. Spectral-domain optical coherence tomography disclosed a hyperreflective band in the foveal region. After 1 week of treatment, disappearance of hyperreflectivity was observed on spectral-domain optical coherence tomography. At 6 months, residual disruption of the outer retinal layer at the fovea remained unchanged. Spectral-domain optical coherence tomography was a useful and sensitive tool for evaluating retinal damage and subsequent resolution after treatment.
