[Pars plana vitrectomy in chronic uveitis]

Sixty-eight patients (74 eyes) with chronic endogenous uveitis underwent pars plana vitrectomy. An increase in visual acuity was observed in 70% postoperatively. Visual results basically depended on the extent of previous damage to the macula. A lensectomy-vitrectomy was done in 23 eyes, while 51 eyes underwent merely a pars plana vitrectomy. The frequency and severity of uveitic relapses were diminished in virtually all cases.
