We report what may be the first evidence-based report of a retinal laser injury to a pilot during commercial flight from a laser device on the ground. Given the significant subjective (blind spot) and objective evidence of focal retinal damage, coupled with the distance involved, we suspect the laser had a radiant power of several watts, known to be injurious to the human retina.
An airline pilot presented to our department complaining of a blind spot in the upper left area of his visual field in the right eye (right supero-nasal scotoma) following exposure to a laser beam while performing a landing maneuver of a commercial aircraft. At around 1300 ft (396 m), a blue laser beam from the ground directly entered his right eye, with immediate flash blindness and pain. Spectral domain ocular coherence tomography highlighted a localized area of photoreceptor disruption corresponding to a well demarcated area of hypofluorescence on fundus autofluorescence, representing a focal outer retinal laser injury. Fundus examination a fortnight later revealed a clinically identifiable lesion in the pilot's right eye commensurate with a retinal-laser burn.
The case reports highlights the growing threat to the ocular health of airline crew and, potentially, passenger safety due to the lack of regulatory oversight of high powered laser devices obtained from the internet. We strongly believe high powered handheld laser devices should not be in the possession of the general public.
我们报告了一起可能是首例基于证据的案例,一名飞行员在商业飞行过程中,被地面上的激光设备造成视网膜激光损伤。鉴于存在明显的主观(盲点)和客观的局灶性视网膜损伤证据,再加上涉及的距离,我们怀疑该激光的辐射功率达数瓦,而这已知会对人类视网膜造成伤害。
一名航空公司飞行员到我们科室就诊,主诉在执行商用飞机着陆操作时,右眼视野左上方区域出现盲点(右上鼻侧暗点),这是在其暴露于一束激光之后出现的情况。在约1300英尺(396米)高度时,一道来自地面的蓝色激光束直接射进他的右眼,当即造成闪光盲和疼痛。频域光学相干断层扫描突出显示了一个光感受器破坏的局部区域,该区域与眼底自发荧光上一个界限清晰的低荧光区域相对应,代表局灶性视网膜外层激光损伤。两周后的眼底检查显示,飞行员右眼出现了一个临床上可识别的病变,与视网膜激光灼伤相符。
该病例报告凸显出由于对从互联网获取的高功率激光设备缺乏监管,航空公司机组人员的眼部健康以及潜在的乘客安全正面临越来越大的威胁。我们坚信普通公众不应持有高功率手持式激光设备。
