branch retinal vein occlusion as a coincident ocular sign of systemic primary cytomegalovirus infection in an immunocompetent status: a case report

purpose : to report a patient with branch retinal vein occlusion (brvo) and serologic evidence of primary cytomegalovirus (cmv) infection case report : we have reported a 27-year-old male with a complaint of sudden decrease in right eye vision starting a few days before. results : immunoglobulin g (igg) seroconversion indicated primary cmv infection. conclusion : involvement and obstruction of small retinal veins may occur in association with primary cmv infection and should be considered in the differential diagnosis of brvo in healthy young adults. an appropriate assay for cmv infection should be done for young patients with retinal vascular occlusion to rule out the diagnosis.    iranian journal of ophthalmology 201224(3):62-64 © 2012 by the iranian society of ophthalmology
