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.
作者报告了一名25岁男性在意外暴露于激光笔不到1秒后，激光笔诱发黄斑病变的频域光学相干断层扫描结果。该3R类激光笔（输出波长532纳米，输出功率3.5至4.5毫瓦[连续波]）具有美国食品药品监督管理局认证。暴露一天后，他右眼出现视力模糊和视物变形。他接受了全身性高剂量皮质类固醇治疗。频域光学相干断层扫描显示在黄斑区有一条高反射带。治疗1周后，频域光学相干断层扫描观察到高反射消失。6个月时，黄斑处视网膜外层的残留破坏保持不变。频域光学相干断层扫描是评估视网膜损伤及治疗后后续恢复情况的有用且敏感的工具。
