Unilateral retinal venous beading

Abstract

Inherited retinal venous beading is a rare retinal vascular disorder that is characterised by tortuosity and beading of the retinal veins. This can potentially lead to vision-threatening complications such as vitreous haemorrhage, macular hard exudation and ischaemia. We report a case of sporadic unilateral retinal venous beading in an 18-year-old white man who was referred by his optician following a routine eye examination. This malformation was unilateral and did not involve any other ocular structure. He had no associated ocular or systemic disorders. When last seen, he did not have any visual complications due to this vascular anomaly.
