Branch retinal arterial occlusion associated with toxoplasmic chorioretinitis

Ocular toxoplasmosis can cause a variety of retinal vascular changes including branch retinal arterial occlusion, which is a rare complication of the disease.

We report a case of toxoplasmic chorioretinitis in a pregnant woman, who developed branch retinal arterial obstruction adjacent to the active chorioretinitis lesion.

The patient received an appropriate steroid and antibiotic treatment and the retinitis lesion resolved over a six-week period. At two months after diagnosis, visual acuity in her right eye was 20/30 and there was a hyperpigmented scar at the site where active retinitis had been observed.

Especially in young patients with branch retinal vascular occlusion associated with posterior uveitis, the diagnosis of ocular toxoplasmosis should be kept in mind and serologic test results should be obtained.
