To present the case of a 37-year-old female with a foveal macrovessel.
The patient had an incidental finding of congenital retinal macrovessel (CRM) in the left eye on optical coherence tomography (OCT). Visual acuity was normal, and slit lamp and dilated fundus examinations were otherwise unremarkable. OCT angiography (OCTA) imaging allowed for visualization of the depth profile of the vessel as well as the foveal avascular zone (FAZ). The FAZ and foveal pit were both smaller in the affected eye compared to the fellow eye.
We describe findings of OCTA imaging in a patient with CRM. Previous reports have relied on examination using fluorescein angiography, which does not provide sufficient axial resolution to discern the different vascular plexuses. This report further characterizes how this rare condition can affect foveal morphology and retinal vasculature.
介绍一名患有黄斑区大血管的37岁女性病例。
患者在光学相干断层扫描（OCT）检查中偶然发现左眼存在先天性视网膜大血管（CRM）。视力正常，裂隙灯检查和散瞳眼底检查未见其他异常。OCT血管造影（OCTA）成像能够显示血管的深度轮廓以及黄斑无血管区（FAZ）。与对侧眼相比，患眼的FAZ和黄斑中心凹均较小。
我们描述了一名CRM患者的OCTA成像结果。既往报告依赖于荧光素血管造影检查，其轴向分辨率不足以分辨不同的血管丛。本报告进一步阐述了这种罕见疾病如何影响黄斑形态和视网膜血管系统。
