A rarely described condition known as branch retinal artery occlusion (BRAO) with concurrent obstruction of the central retinal vein (CRVO) is characterized by diffuse retinal hemorrhages, dilated and tortuous retinal veins, macular and disc edema, cotton wool spots, and a generalized delay in arteriovenous transit on fluorescein angiography, together with a retinal whitening in the area of the affected retinal arterial branch. Although BRAO and CRVO may share underlying systemic risk factors, the pathogenesis of combined BRAO + CRVO is still unknown. We present a BRAO + CRVO case report concerning a 63-year-old white male who came to our observation complaining of sudden vision loss in his right eye. An increased risk for thrombotic event was revealed in this case, and the patient improved only with systemic anticoagulant therapy and in the absence of ocular therapy. We also explain all the clinical findings that are detectable using different diagnostic devices and analyze the scientific literature for other, similar clinical cases.
一种罕见的疾病，称为分支视网膜动脉阻塞（BRAO）合并中央视网膜静脉阻塞（CRVO），其特征是弥漫性视网膜出血、扩张和扭曲的视网膜静脉、黄斑和视盘水肿、棉絮斑以及荧光素血管造影时动脉静脉转运普遍延迟，同时受影响的视网膜动脉分支区域的视网膜变白。尽管 BRAO 和 CRVO 可能有共同的潜在系统性危险因素，但联合 BRAO + CRVO 的发病机制尚不清楚。我们报告了一例 BRAO + CRVO 病例，涉及一名 63 岁的白人男性，他因右眼突然视力丧失前来就诊。该病例显示出血栓形成事件的风险增加，仅通过全身抗凝治疗且不进行眼部治疗，患者才有所改善。我们还解释了使用不同诊断设备可检测到的所有临床发现，并对其他类似临床病例的科学文献进行了分析。
