Macular hole secondary to toxoplasmic retinochoroiditis

Ocular toxoplasmosis causes abnormalities in the vitreous that are responsible for several types of well-known complications including retinal detachment and epiretinal membranes. We report on a patient who developed toxoplasmic panuveitis with a full-thickness macular hole (MH) and was successfully treated with vitreoretinal surgery. A 35-year-old Hispanic female presented with a 2-week history of loss of visual acuity and metamorphopsia in her right eye. Funduscopy revealed a typical toxoplasmosis lesion and a MH, which was confirmed by optical coherence tomography. After 8 weeks of medical treatment with sulfamethoxazole (800 mg)/trimethoprim (160 mg) and steroids, the intraocular inflammation was considered inactive. Pars plana vitrectomy with inner limiting membrane peeling and injection of 24 % sulphur hexafluoride gas were performed to treat the MH, without success. Repeat pars plana vitrectomy was then performed with injection of 14 % perfluoropropane (C₃F₈). Closure of the MH was achieved after this second procedure. Vitreoretinal surgery may be safe and effective for treating MHs secondary to toxoplasmosis lesions, a very uncommon complication of this disease.
