We report a case of accidental thermal injury due to improper use of a laser pointer obtained outside of the United States. A 13-year-old received a laser pointer as a gift and looked at a reflection of the beam. The patient underwent full ophthalmologic examination with fundus photography, spectral domain optical coherence tomography, and fluorescein angiography. Visual acuity in the left eye was 20/100 at presentation. Fundus examination and ancillary tests were consistent with thermal macular injury. The laser pointer was analyzed and found to be a green diode laser with average power output of 154 mW.
我们报告一例因不当使用在美国境外获得的激光笔导致的意外热损伤病例。一名13岁儿童收到一支激光笔作为礼物,并注视了光束的反射。患者接受了全面的眼科检查,包括眼底照相、光谱域光学相干断层扫描和荧光素血管造影。初诊时左眼视力为20/100。眼底检查和辅助检查结果与黄斑热损伤相符。对该激光笔进行分析后发现是一支平均功率输出为154毫瓦的绿色二极管激光笔。
