An Interesting Case of Acute Chorioretinitis Due to Ocular Toxoplasmosis

Abstract

Ocular Toxoplasmosis is a recurrent and progressive necrotizing retinitis that can cause blindness. In most cases, it manifests as a localised retinochoroidal lesion and is the most prevalent cause of posterior uveitis worldwide. Ocular infection is relatively common, with the majority of cases being asymptomatic. As a result, it's important to draw attention to this blinding disease that might go undetected, as well as the preventative actions that can be taken to avoid vision impairment. We report a case of a 35 years old female came with complaints of defective vision in both eyes for past 2 months which was acute in onset and painless in nature. There was history of similar episode 1 year back with no history of any treatment taken and there was a history of eating undercooked meat in the past. Right eye fundus showed a typical headlight in the fog appearance and left eye fundus showed exudative sheathing of vessel wall and multiple pigmented old retinochoroidal scars. Blood investigation showed elevated total count and an elevated ESR level. Peripheral smear report suggested dimorphic anemia and thrombocytosis. Antinuclear antobody- positive.Toxoplasm igG antibody- 511.90IU/ml (positive for toxoplasmosis).
