    Abstract:
    The authors evaluate the role of intravitreal trimethoprim/sulfamethoxazole in the treatment of toxoplasma retinochoroiditis (TRC) in four patients. Intravitreal injection of trimethoprim/sulfamethoxazole 1.28 mg/0.08 mL with dexamethasone 400 µg/0.1 mL was injected weekly or biweekly. After the initiation of treatment, a reduction in intraocular inflammation was observed clinically and on optical coherence tomography within 1 week. Three patients regained visual acuity of 20/20, and one patient improved to 20/40 with residual macular scarring. No evidence of retinal toxicity was noted on full-field electroretinogram. Intravitreal trimethoprim/sulfamethoxazole and dexamethasone combination may be an alternative treatment strategy in patients with TRC.
