摘要
PURPOSE: To report a patient with a macular injury caused by a laser pointing device. METHODS: Case report. A healthy 34-year-old man was examined 2 days after he deliberately gazed into the beam of a laser-pointing device with his left eye for an estimated 30 to 60 seconds. His uncorrected visual acuity in each eye was 20/20. He reported a transient central scotoma in the left eye and headache after laser exposure. RESULTS: Both eyes were unremarkable except for a focal retinal pigment epithelial disturbance at the nasal edge of the fovea in the left eye. Fundus fluorescein angiography demonstrated window- defect type hyperfluorescence in the same location. CONCLUSIONS: Laser-pointing devices may cause macular injury when used inappropriately. Conformance with consumer safety recommendations should minimize potential hazards. (C) 1.995 by Elsevier Science Inc. All rights reserved.
