[Pars plana vitrectomy--results and complication of 100 consecutive cases (author's transl)].

Indications, results and complications of 100 consecutive cases of pars plana vitrectomy are reported. In 83% of patients with anterior segment and/or vitreous opacities a clear view to the fundus could be obtained; visual acuity improved significantly in 73%. Complicated retinal detachments, not managable with conventional retinal surgery, could be reattached in 26% of the cases. In carefully selected patients vitrectomy was indicated to stabilize the anatomic situation and to prevent further visual deterioration.
