Purpose: To present cases of toxoplasmic retinochoroiditis (TRC) treated successfully with intravitreal clindamycin injection.
Case summary: (Case 1) A 41-year-old man presented with blurred left eye vision for several months. The patient had a large chorioretinal scar with infiltrations at the boundaries, and fluorescein angiography (FA) showed active retinochoroiditis. Antitoxoplasmosis (antiTX) immunoglobulin G (IgG) was positive, and the patient was started on antiTX medication. Despite several weeks of treatment with maximum doses of antiTx, the TRC progressed and visual acuity worsened. Pars plana vitrectomy (PPV) with intravitreal clindamycin injection (1.0 mg/0.1 ml) was performed, and an additional injection was given 4 weeks later. Six weeks after the second injection, TRC wascompletely resolved with 20/20 vision. (Case 2) A 67-year-old man presented with decreased left eye vision for 1 year. Fundus examinations showed vitreous opacity and epiretinal membranes. The FA revealed retinochoroiditis and the antiTX IgG titer was elevated. The presumed diagnosis was TRC, and oral medications of trimethoprim-sulfamethoxazole, clindamycin, and prednisolone was administered. Inflammation began to improve however, as the patient was not tolerating systemic antiTx medications, an intravitreal injection of clindamycin (1.0 mg/0.1 ml) was administered with PPV. The patientdiscontinued oral medication after surgery, and the inflammation resolved 5 weeks later.
Conclusions: Intravitreal clindamycin injections may be an additional treatment option for TRC in patients who are unable to tolerate systemic therapy or whose disease progresses despite systemic therapy.
