Laser pointers originally designed for use during presentations are ubiquitous and are even sold as toys (such as pens or on key chains) in drug stores. Though reported as safe, the laser pointers still carry the risk of potential damage to the eye. We report a 16-year-old boy with bilateral retinal injury caused by 20-30 seconds of exposure to a laser pointing-device. Immediately thereafter, vision was blurred bilaterally and he noted a central red scotoma in each eye. Symptoms resolved spontaneously within 2 days but the retinal scars remained all during the 10 months of follow-up. It is clear from our report and 3 other publications that retinal damage can develop from misusing laser pointers. Laser hazards and safety should be stressed for the general public. We recommend that laser-pointers should not be available as toys to children and teenagers.
最初设计用于演示的激光笔随处可见，甚至在药店作为玩具出售（如笔形或钥匙链形）。尽管被报告为安全，但激光笔仍有对眼睛造成潜在损害的风险。我们报告了一名16岁男孩，因暴露于激光笔20 - 30秒而导致双侧视网膜损伤。此后，他立即双侧视力模糊，并注意到每只眼睛中央有红色暗点。症状在2天内自行缓解，但在10个月的随访期间视网膜瘢痕一直存在。从我们的报告和其他3篇出版物可以清楚地看出，滥用激光笔会导致视网膜损伤。应向公众强调激光危害和安全性。我们建议激光笔不应作为玩具提供给儿童和青少年。
