Branch retinal artery occlusion (BRAO) is a relatively rare vascular disorder characterized by the occlusion of one or more branches of the central retinal artery, with an incidence of around 5 per 100,000 persons per year. Its ability to cause permanent vision loss in a specific visual field makes it a significant clinical obstacle that requires careful management. We describe a case of a 77-year-old male patient, a known hypertensive (on medication and whose hypertension was under control), presented with sudden painless loss of vision in the superior field of his right eye. Timely and accurate diagnosis is crucial to initiate appropriate management. Patients with hypertension should be routinely screened for its various micro- and macrovascular complications, and prophylactic therapy/management should be started wherever warranted.
视网膜分支动脉阻塞（BRAO）是一种相对罕见的血管疾病，其特征是视网膜中央动脉的一个或多个分支发生阻塞，每年发病率约为每10万人中有5例。它能够导致特定视野内的永久性视力丧失，这使其成为一个需要谨慎处理的重大临床难题。我们描述了一例77岁男性患者，该患者已知患有高血压（正在服药且高血压得到控制），出现右眼上半视野突然无痛性视力丧失。及时准确的诊断对于启动适当的治疗至关重要。高血压患者应常规筛查其各种微血管和大血管并发症，如有必要应开始预防性治疗/处理。
