Abstract

We investigated the poor prognostic factors for trans pars plana vitrectomy in the complicated cases of proliferative diabetic retinopathy. A total of 150 eyes in 125 patients with complications of diabetic retinopathy were treated surgically. The postoperative visual acuity was decreased according to Snellen E chart compared to the preoperative in 53 eyes out of 150 eyes. The cases with poor visual outcomes are as follows; 4 cases with rubeosis iridis, 12 of 14 cases with retinal detachment involving three qua tors of the retina including the fovea, 6 cases with increased IOP(>21 mmHg) and 23 of 30 cases with chronic renal failure.
