Diffuse toxoplasmic retinochoroiditis in a patient with AIDS.

Ocular toxoplasmosis typically presents as a focal necrotizing retinochoroiditis. We report a case of diffuse necrotizing retinochoroiditis due to toxoplasmosis in a patient with the acquired immunodeficiency syndrome (AIDS). The appearance at initial presentation was similar to the acute retinal necrosis syndrome. We recommend that toxoplasmosis be considered in the differential diagnosis of diffuse retinal necrosis in patients with AIDS. Although systemic disseminated toxoplasmosis is not rare in AIDS, this is, to our knowledge, the first reported case of diffuse ocular involvement.
