To report a case of macular damage from a laser pointer.
Case report. A 19-year-old woman had an acute reduction of visual acuity in the right eye after deliberately staring into a commercial class 2 laser pointer for approximately 10 seconds.
The patient's best-corrected visual acuity was RE: 20/40, and she had two small pericentral scotomata, as well as a hypopigmented ring-shaped lesion in the fovea. Within 8 weeks, her visual acuity improved to 20/20 and visual field returned to normal, but a subjective relative decrease in brightness of objects viewed by the right eye was apparent. Retinal pigment epithelial abnormality persisted.
Commercial laser pointers, commonly used for teaching and entertainment purposes, may cause notable macular damage if abused. Morphologically, this may manifest as foveal retinal pigment epithelial disturbance.
报告一例因激光笔导致黄斑损伤的病例。
病例报告。一名19岁女性在故意注视一支商用2类激光笔约10秒后，右眼视力急剧下降。
患者最佳矫正视力为右眼20/40，有两个小的中心旁暗点，以及黄斑区色素减退的环形病变。8周内，她的视力提高到20/20，视野恢复正常，但右眼观察物体时主观亮度相对下降明显。视网膜色素上皮异常持续存在。
常用于教学和娱乐目的的商用激光笔如果滥用可能会导致明显的黄斑损伤。在形态学上，这可能表现为黄斑区视网膜色素上皮紊乱。
