In 14 eyes undergoing a pars plana filtration procedure combined with pars plana lensectomy and vitrectomy, the most common complication was a severe sterile fibrinous vitritis. However, after a mean follow-up period of 6.3 months, intraocular pressure was controlled in five eyes (36%) after the procedure alone, in two (14%) after subsequent medical therapy, and in three (21%) after subsequent cyclocryotherapy. Preoperative visual acuity was maintained or improved in nine of the eyes (64%), whereas four eyes (28%) had no light perception.
