Branch retinal vein obstruction secondary to retinal arteriovenous communication.

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.
