Congenital retinal macrovessel (CRM) is a rare vascular abnormality of the macular region that is usually discovered incidentally.

We present the case of a 57-year-old Libyan female patient with a CRM.

The patient's left eye showed an abnormally large retinal vein crossing the foveal avascular region, Optical coherence tomographic angiography (OCTA) showed a large retinal vessel in the left eye branching superiorly at the edge of the fovea a vascular zone. The patient has no visual defect or macular thickening.

CRM is an incidental finding that, with rare exceptions, does not cause any alteration to the patient's vision. They can be imaged by OCTA and need to be differentiated from other retinal pathologies.
