Pars plana vitrectomy for vitreous opacity secondary to presumed toxoplasmosis

C. R. Fitzgerald

Four patients with vitreous opacity characterized by veil-like membranes with precipitates of presumed inflammatory cells had visual acuities in the affected eye of hand movements only, 20/200, 20/400, and 20/400 over a period of six months or longer. A history compatible with episodes of inflammation secondary to toxoplasmosis and a chorioretinal scar compatible with toxoplasmosis in the involved or opposite eye was present in each patient. Pars plana vitrectomy (with lensectomy in three of the four cases) has afforded information in regard to preoperative and postoperative management of such patients, as well as postoperative results.
