Segmental retinal periarteritis as a complication of toxoplasmosis.

Segmental retinal periarteritis is a relatively rare clinical entity with varied etiologies. This report describes a case of acute toxoplasmosis with segmental periarteritis without concomitant periphlebitis. To my knowledge this has never been reported previously. The diagnosis of toxoplasmosis was proven by both clinical findings and serology.
