title: Unusual presentation of acute ocular toxoplasmosis.
abstract: Two unusual cases of ocular toxoplasmosis are presented. A 24 year old woman developed retinal and optic nerve neovascularization in conjunction with acute ocular toxoplasmosis. The neovascularization regressed with resolution of the inflammation. The possibility of retinal ischemia or inflammation alone as an etiology are discussed. A 19 year old woman developed optic nerve edema and a marked decrease in vision associated with a nasal toxoplasma lesion and a macular star. With resolution of the process, optic atrophy developed but visual acuity returned to normal. Optic nerve edema and atrophy were felt to result from diffuse inflammation, but not from focal involvement in the nerve itself with the organism.
