Prepapillary vascular loops are rare congenital vascular abnormalities of the retinal vasculature. This mostly benign condition can sometimes cause complications such as branch retinal artery occlusion and vitreous haemorrhage. Disc collaterals, neovascularisation of the optic disc, idiopathic retinal vasculitis, aneurysms and neuroretinitis (IRVAN) syndrome and Wyburn Mason syndrome should be kept in mind for the vascular differential diagnosis. In addition, when the loops present bilaterally and settle into the region adjacent to the optic disc border, they can be misdiagnosed as papilloedema. The diagnosis is usually made clinically by careful fundus examination. Optical coherence tomography and fundus fluorescein angiography might serve as ancillary tools for the diagnosis. In this report, we present a 52-year-old male with bilateral prepapillary arterial loops referred to our clinic with a preliminary diagnosis of papilloedema.
视乳头前血管袢是视网膜血管系统罕见的先天性血管异常。这种大多为良性的情况有时会引起诸如视网膜分支动脉阻塞和玻璃体出血等并发症。在进行血管鉴别诊断时，应考虑视盘侧支循环、视盘新生血管形成、特发性视网膜血管炎、动脉瘤以及神经视网膜病变（IRVAN）综合征和怀伯恩·梅森综合征。此外，当血管袢双侧出现并位于视盘边界附近区域时，可能会被误诊为视乳头水肿。诊断通常通过仔细的眼底检查在临床上做出。光学相干断层扫描和眼底荧光血管造影可作为辅助诊断工具。在本报告中，我们介绍了一名52岁男性，双侧视乳头前动脉袢，初步诊断为视乳头水肿，转诊至我们诊所。
