Abstract

Toxoplasmosis is the most common cause of posterior uveitis in the world. This study described the clinical characteristics and visual outcome of 193 patients with ocular toxoplasmosis at Feiz Hospital (Isfahan, Iran) during the last six years. The setting and design used was a retrospective non-comparative observational case series. In this study, 193 patients with ocular toxoplasmosis (111 female, 82 male) were enrolled. The distribution of symptoms and fundoscopic findings were studied. The most-reported chief complaint was blurred vision in 96 % (184 patients) and floaters in 13.47 % (25 patients) of cases and most frequent clinical manifestations were chorioretinitis 98.48 % (190 patients), macular scars 50.7 % (98 patients), and atrophic optic papilla two (1.03 %) patients. Primary retinal lesions were observed in 16 (8.2 %) and combination of active lesions and old retinochoroidal scars in 177 (91.7 %) of the patients. Retinal detachment occurred in 11 (5.69 %) patients. Bilateral involvement was found in 27 % of patients. Blindness was 0.05 % after treatment. Recurrence rate was 14.5 %. In conclusion, ocular toxoplasmosis substantially varies among patients with different age, gender, site of lesion and other factors. Suddenly blurred vision, floater, and pain could be caused by Toxoplasma gondii. Flashing, may necessitate a more precise peripheral fundus examination.
