ABSTRACT

Background: The diagnosis of ocular toxoplasmosis is often based in presence of characteristic clinical findings include focal retinochoroiditis and adjacent at the edge retino choroidal scar and vitreous inflammation. Nevertheless not all the patients show the same clinical picture. Purpose: to demonstrate the characteristics of the atypical toxoplasmosis in a population diagnosed with ocular toxoplasmosis. Methods: It is a clinical retrospective, observational study developed in the Clinic of Uveitis on the HGM. We review the files with diagnosis of ocular toxoplasmosis from 1996 to 2005, we select cases that didn’t correspond to the clinical typical picture, with determination of IgG, IgM by ELISA and therapeutic trial of antibiotics active against toxoplasmosis. Results: Out of 107 patients with ocular toxoplasmosis, 8 cases (7.5%) were considered atypical for the following characteristics: papilitis with vitreous inflammation and vasculitis nearby with atrophic peripapilar and defects on visual fields altitudinal, (two cases). Bilateral panuveitis (two cases) Fuchs uveitis (one) pseudomultiple retinochoroiditis (one) retinal vasculitis (one) and scleritis (one). All the patients were positive to IgG and only 2 cases were positive to IgM. They all respond well to the specific treatment (trimethoprim-sulfamethoxazole and minocicline) only patients with papilitis received prednisone for a month. Conclusions: the atypical ocular toxoplasmosis is a type of uveitis in patients immunocompetents in which the clinical picture is different. They respond to the specific therapy and they have the positive IgG.
