Congenital retinal macrovessel with macular edema: An unusual presentation

Abstract

Congenital retinal macrovessel (CRM) is a rare developmental condition in which a large vein, artery, or occasionally an artery and a vein together, cross the macular region. Most often, this aberrant vessel originates from a branch of the inferotemporal vein, with branches crossing the horizontal raphe. CRMs do not affect vision unless there are associated foveolar cysts, foveal ectopia, pigmentary changes at fovea, macular hemorrhage, exudates, serous macular detachment, or the macrovessel crosses the fovea. We present a case of a 13-year-old male patient with congenital macular artery crossing the fovea, associated with macular edema and decreased visual acuity. In this case report, we highlight the fundus fluorescein angiography findings and optical coherence tomography evaluation of the patient.
