REACTIVATION OF OCULAR TOXOPLASMOSIS AFTER PARS PLANA VITRECTOMY

OpenAlex English

PURPOSE: To report a case with reactivation of toxoplasma choroiretinitis after pars plana vitrectomy. PATIENTS AND METHODS: A 58-year-old female patient was diagnosed with secondary epiretinal membrane in her right eye. Bimanual 23-gauge pars plana vitrectomy and membrane peeling was performed. At first week postoperatively, visual acuity decreased; in slit-lamp examination, there were 3+ cells in the anterior chamber with keratic precipitate. Fundoscopic examination revealed reactivation of chorioretinitis adjacent to the previous scar. RESULTS: The patient was diagnosed with reactivation of toxoplasma chorioretinitis and treated with oral trimethoprim-sulfamethoxazole, clindamycin and topical prednisolon acetate, and cyclopentolate drops for 5 weeks. Forty-eight hours after initiation of antibiotics, oral prednisone was added to the regimen and the dose was tapered to zero over the following 5 weeks. After 3 weeks of treatment, lesion was inactivated. CONCLUSION: Ocular toxoplasmosis reactivation may develop after pars plana vitrectomy. After intraocular surgery, reactivation of ocular toxoplasmosis should be considered in the follow-up.
