ABSTRACT
Purpose: To describe fulminant toxoplasma retinochoroiditis induced by corticosteroid monotherapy.
Methods: Clinical records of nine patients were reviewed.
Results: All patients (five female, four male; aged 15–64 years) had been misdiagnosed as unilateral non-infectious uveitis and given systemic and/or local corticosteroid injections elsewhere. Mean disease duration before referral was 105.6 ± 71 (45–240) days. Visual acuity at presentation was <20/200 in six eyes. Average lesion size was 6.6 disc areas in eight eyes and all four quadrants were involved in one. Toxoplasma DNA was detected in eight tested eyes. Mean duration of anti-toxoplasmic therapy was 92.5 ± 37.1 days. Three eyes developed rhegmatogenous retinal detachment. Four patients underwent pars plana vitrectomy. Final visual acuity was <20/200 in five eyes.
Conclusions: Iatrogenic immunosuppression due to initial misdiagnosis may lead to an aggressive course and serious complications of ocular toxoplasmosis, a potentially self-limiting infection.
