RESUMO
We report two cases of fulminant toxoplasmic retinochoroiditis following intravitreal triamcinolone acetonide (IVTA) administration. Case 1: A 42-year-old female received IVTA for presumed non-infectious panuveitis. Within 2 months, she developed diffuse macular retinochoroiditis with optic disc edema. Upon starting anti-toxoplasmic therapy (ATT), her intraocular inflammation resolved with catastrophic damage to the disc and macula. Case 2: A 30-year-old male received IVTA for presumed reactivation of previously scarred toxoplasmic retinochoroiditis. Despite simultaneous ATT, within 6 weeks, he developed extensive, multifocal macular retinochoroiditis. He continued to require ATT for 18 months and later underwent vitrectomy with silicone oil placement for severe epiretinal proliferation. Aqueous tap polymerase chain reactions were found positive for Toxoplasma gondii in both cases. In conclusion, IVTA administration can lead to fulminant toxoplasmic retinochoroiditis even when used with appropriate ATT. Extreme caution should be exercised while administering depot corticosteroids in eyes with panuveitis of unknown origin.

Retinitis and panuveitis in immunocompetent patients is a rare and sight-threatening disease, of difficult diagnosis. A case of a 31-year-old male who presented with unilateral placoid retinitis and panuveitis, unsuccessfully treated as acute retinal necrosis, that in fact was syphilis, with neurosyphilis and excellent response to treatment is reported.
Retinite com panuveíte em pacientes imunocompetentes é um condição rara e ameaçadora para a visão, e de difícil diagnóstico. É relatado um caso de um paciente do sexo masculino com 31 anos de idade, que se apresentou com retinite em placas e panuveíte, inicialmente tratado sem sucesso como necrose aguda de retina, que na verdade era um caso de sífilis ocular, com afecção do sistema nervoso central e ótima resposta ao tratamento sistêmico para sífilis.
