title: Glaucoma after pars plana vitrectomy.
abstract: Elevation of intraocular pressure is a relatively common complication after pars plana vitrectomy. Seven cases illustrate the diverse causes of the pressure rise that may be seen in these patients. Blood in the anterior chamber, retained lens material, inflammatory debris, topical corticosteroid administration, rubeosis iridis, and pre-existing, chronic open-angle glaucoma have all been implicated, singly or in combination, in the elevation of intraocular pressure that occurs after pars plana vitrectomy. Diabetic patients are particularly susceptible to the simultaneous occurrence of more than one of these factors.
