Laser use has become common in the home and workplace. We present a review of laser eye injuries and guidance for the emergency medicine physician on evaluation of laser eye injury-related complaints.
A review of the literature on the potential for injury, concerning signs and symptoms, evaluation, and referral recommendations is discussed.
The scientific literature finds that laser eye injuries are uncommon from use of nonindustrial lasers. Furthermore, an eye injury from a regulated Class 2 or Class 3A by a transient sweep across the line of vision does not result in injury, but injury can occur with a direct intentional prolonged exposure.
Patient's history of the length and type of laser exposure is important. A significant direct eye exposure to a laser, persistent after images, and decreased visual acuity should initiate urgent referral to an ophthalmologist for further ophthalmologic testing. Brief laser exposure or indirect exposures with complaints of headaches or blurry vision require other diagnostic explanations.
激光在家庭和工作场所的使用已变得很普遍。我们对激光眼损伤进行综述，并为急诊医学医生提供有关评估激光眼损伤相关主诉的指导。
讨论了关于损伤可能性、相关体征和症状、评估及转诊建议的文献综述。
科学文献发现，非工业用激光导致的眼损伤并不常见。此外，短暂扫过视线的2类或3A类受管制激光不会造成眼损伤，但直接故意长时间暴露则可能导致损伤。
患者激光暴露的时长和类型的病史很重要。激光直接显著暴露于眼睛、有持续的后像以及视力下降，应立即转诊至眼科医生处进行进一步眼科检查。短暂激光暴露或间接暴露且伴有头痛或视力模糊主诉的情况需要其他诊断解释。
