Congenital retinal macrovessels (CRM) are large aberrant blood vessels that cross the horizontal raphe. Visual acuity may be negatively affected in cases afflicted with CRM due to macular serous detachment, hemorrhage, exudation, foveolar cyst formation and retinal artery occlusion. Even the presence of an anomalous vessel itself running through the foveal avascular zone may compromise the visual acuity. In this case report, we discuss the multimodal imaging characteristics of a case of symptomatic unilateral CRM-related cystoid macular edema and serous macular detachment in a 13-year-old boy. Optical coherence tomography angiography (OCTA) imaging of the superficial retina revealed the aberrant vessel and anomalous arteriovenous communication between the aberrant vessel and the retinal artery. The foveal avascular zone also appeared partly distorted. The present case reports the second-youngest patient afflicted with unilateral CRM and associated macular edema. There was spontaneous resolution of macular edema within six weeks. In light of the observations in this case and the literature review, the need to refrain from rapid therapeutic intervention in the eyes of patients affected with CRM and macular edema must be emphasized.
先天性视网膜大血管（CRM）是跨越水平中线的粗大异常血管。患有CRM的患者，由于黄斑浆液性脱离、出血、渗出、中心小凹囊肿形成和视网膜动脉阻塞，视力可能会受到负面影响。即使有一条异常血管穿过黄斑无血管区，也可能损害视力。在本病例报告中，我们讨论了一名13岁男孩单侧CRM相关的黄斑囊样水肿和浆液性黄斑脱离的多模态成像特征。浅层视网膜的光学相干断层扫描血管造影（OCTA）成像显示了异常血管以及该异常血管与视网膜动脉之间的异常动静脉交通。黄斑无血管区也出现了部分扭曲。本病例报告的是第二年轻的单侧CRM并伴有黄斑水肿的患者。黄斑水肿在六周内自行消退。鉴于本病例的观察结果和文献综述，必须强调对于患有CRM和黄斑水肿的患者，在眼部治疗时应避免进行快速干预。
