Branch retinal artery occlusion associated with congenital retinal macrovessel

Neha Goel et al. Oman J Ophthalmol. 2014 May.

Abstract

A congenital retinal macrovessel (CRM) is a large retinal vessel, usually a vein, which traverses through the central macula and has large tributaries extending on both sides of the horizontal raphe. In the majority of cases, CRM have no effect on visual acuity, although in rare cases, macular hemorrhage, foveolar cysts, serous macular detachment, and the presence of the anomalous vessel in the foveola can affect vision. We describe a case of CRM with decreased vision secondary to a branch retinal artery occlusion (BRAO). To the best of our knowledge, this association has not been reported previously.

Keywords: Congenital retinal macrovessel; aberrant retinal vessels; branch retinal artery occlusion; macular thickness; optical coherence tomography; retinal nerve fiber layer thickness.

The inferotemporal vessels are attenuated. (b) Fluorescein angiogram showing multiple arteriovenous communications around the CRM. Horizontal (c) and vertical (d) SD-OCT scans through the macula showing marked thinning of the macula inferiorly especially involving the inner retinal layers. A macular thickness map (e) confirms that the superior quadrant is unaffected
