Branch retinal artery occlusion associated with ocular toxoplasmosis. (a) Color fundus photograph of the left eye of a patient with ocular toxoplasmosis shows an active focus of retinochorioretinitis (white arrow) adjacent to old pigmented scars infero-temporally and an area of retinal whitening along the inferior temporal arcade (black arrows). (b) Early phase fluorescein angiogram shows delayed filling of inferior temporal branch retinal artery, capillary nonperfusion corresponding to the area of retinal whitening, and hypofluorescence of the focus of retinochoroiditis. (c) Color fundus photograph 3 months later shows resolution of the retinal whitening. Note the presence of a persistent scotoma on automated perimetry (d).
