To report symptoms and ocular pathology in 13 patients exposed to light from laser pointers.
We conducted a multi-centre consecutive case series from eight ophthalmology departments.
Eleven boys aged 9-15 years and two girls aged 7 (sister of one of the aforementioned boys) and 12 years, respectively, were included. Laser wavelengths were 572 nm (green), 450 nm (blue), and red laser of unknown wavelength. Output powers were between 5 and 5000 mW. Evaluation included slit lamp examination, colour fundus photography (CFP), and optical coherence tomography (OCT). All subjects complained of unilateral vision loss. Initial visual acuities in exposed eyes ranged from 0.05 to 1.0 Snellen equivalent or better. Nine subjects showed pathology on CFP and OCT abnormalities. One subject had a macular hole, which closed after vitrectomy. Long-term visual acuity ranged from 0.3 to 1.0 Snellen equivalent or better.
High-powered laser pointers have become readily available on the internet, and they have the potential to induce lasting visual loss. More than half of the published laser pointer maculopathy cases since the first incidence in 1999 have been published in 2014-2017. We suspect that incidence of exposure and subsequent visual loss is rising, and we encourage national legislators to regulate this market.
报告 13 名激光笔照射眼部患者的症状和眼部病变。
我们进行了一项多中心连续病例系列研究，涉及 8 个眼科部门。
共纳入 11 名 9-15 岁男孩和 2 名 7（上述男孩之一的妹妹）和 12 岁的女孩，激光波长分别为 572nm（绿色）、450nm（蓝色）和未知波长的红色激光，输出功率在 5 至 5000mW 之间。评估包括裂隙灯检查、眼底彩色照相（CFP）和光学相干断层扫描（OCT）。所有患者均主诉单侧视力丧失。暴露眼的初始视力从 0.05 至 1.0 或更好的 Snellen 等效视力不等。9 名患者的 CFP 和 OCT 异常。1 名患者出现黄斑裂孔，玻璃体切除后闭合。长期视力从 0.3 至 1.0 或更好的 Snellen 等效视力不等。
高功率激光笔在互联网上变得易于获得，它们有可能导致持久的视力丧失。自 1999 年首例激光笔黄斑病变病例以来，超过一半的已发表病例发表于 2014-2017 年。我们怀疑暴露和随后视力丧失的发生率正在上升，我们鼓励国家立法者规范这一市场。
