This document describes a case of toxoplasmosis retinochoroiditis in a 26-year-old male who presented with sudden loss of vision in his left eye. Examination found inflammation and a white lesion in the left eye along with old scarring. Tests supported a diagnosis of toxoplasmosis. The patient was treated with systemic antiparasitic medications and steroids, along with topical steroids and cycloplegics. Toxoplasmosis results from infection by the protozoan Toxoplasma gondii and commonly causes posterior uveitis, with retinitis developing near old scars when immunity is suppressed.
