Branch retinal vein obstruction secondary to retinal arteriovenous communication

Abstract

PURPOSE: To document a branch retinal vein obstruction secondary to a congenital arteriovenous communication.METHOD: Case report of a young patient with retinal arteriovenous communication.RESULTS: A 12-year-old girl had a grade 2 retinal arteriovenous communication in her right eye. She was asymptomatic and was subsequently followed up. Magnetic resonance imaging of the brain was normal and disclosed no signs of Wyburn-Mason syndrome. Nine years later, she developed a branch retinal vein obstruction in the area of the arteriovenous communication. Six months later, the patient was free of secondary complications of branch retinal vein obstruction; however, she is being followed up to detect any retinal or iris neovascularization.CONCLUSION: Awareness of retinal vascular obstruction associated with arteriovenous communication may help its timely recognition, as well as prompt treatment of potential complications, such as retinal and iris neovascularization.
