To report a case of branch retinal artery occlusion associated with paracentral acute middle maculopathy on spectral-domain optical coherence tomography presumably related to heavy cannabis consumption.
Retrospective case report. Spectral-domain optical coherence tomography, fluorescein angiography, and optical coherence tomography angiography were performed.
A 21-year-old healthy man described the acute onset of superior visual field loss in his right eye. He admitted smoking approximately 15 g daily of cannabis for several weeks during COVID-19 confinement. Ophthalmoscopic examination of the right eye showed inferotemporal retinal whitening. Spectral-domain optical coherence tomography illustrated evidence of the ischemic cascade with diffuse hyperreflectivity of the inner and middle retinal layers within the central region of the retinal infarct and paracentral acute middle maculopathy at the border of the infarct. Optical coherence tomography angiography demonstrated predominant flow signal loss at the level of the deep retinal capillary plexus. Fluorescein angiography and complete systemic workup were unremarkable.
Branch retinal artery occlusion and paracentral acute middle maculopathy may be related to heavy cannabis use as the result of transient arterial vasospasm.
报告 1 例与光相干断层扫描（OCT）所见旁中心性急性中黄斑病变相关的分支视网膜动脉阻塞病例，该病变可能与大量吸食大麻有关。
回顾性病例报告。进行了频域 OCT、荧光素眼底血管造影和 OCT 血管造影检查。
1 名 21 岁健康男性自述右眼急性视野缺损。他承认在 COVID-19 隔离期间，每周大约吸食 15 克大麻。右眼眼底检查显示颞下视网膜变白。频域 OCT 显示出缺血级联的证据，在视网膜梗死中央区域的内层和中层视网膜弥漫性高反射，在梗死边缘出现旁中心性急性中黄斑病变。OCT 血管造影显示深层视网膜毛细血管丛水平的血流信号明显缺失。荧光素眼底血管造影和完整的系统检查无明显异常。
分支视网膜动脉阻塞和旁中心性急性中黄斑病变可能与大量吸食大麻导致的短暂动脉血管痉挛有关。
