Congenital retinal macrovessels (CRM) represent rare aberrant vasculature of the retinal vessels that can supply or drain the macula. In this report, the optical coherence tomography angiography features of a congenital retinal macrovessel are discussed.
The history and examination findings are presented alongside swept-source OCT angiography with corresponding B scan and en face OCT imaging.
The case is a 12-year-old female patient with excellent best-corrected visual acuity in both eyes.
Swept-source OCT angiography demonstrated considerable loss of the foveal avascular zone at the levels of the superficial and deep capillary plexus.
In this case there was no detrimental effect on vision despite anatomical loss of the foveal avascular zone.
先天性视网膜大血管（CRM）是视网膜血管罕见的异常血管，可供应或引流黄斑区。在本报告中，讨论了先天性视网膜大血管的光学相干断层扫描血管造影特征。
结合扫频源光学相干断层扫描血管造影及相应的B超扫描和正面光学相干断层扫描成像，展示病史和检查结果。
该病例为一名12岁女性患者，双眼最佳矫正视力良好。
扫频源光学相干断层扫描血管造影显示，在浅表和深部毛细血管丛水平，黄斑无血管区有明显缺失。
在该病例中，尽管黄斑无血管区出现解剖学缺失，但对视力并无不利影响。
