Primary intraocular (retinal) lymphoma after ocular toxoplasmosis.

Purpose: Toxoplasmosis gondii is a common worldwide parasite that presents in the eye with focal retinochoriditis and vitritis. Although it is rare, ocular toxoplasmosis has been linked to primary intraocular (retinal) lymphoma, which is mostly a diffuse large B-cell lymphoma.

Methods: An elderly female patient was treated for recurrent ocular toxoplasmosis, and because of progressive vitritis, a diagnostic vitrectomy was performed.
