| Abstract |
|
The retrospective study of seventy eight eyes which were underwent the pars plana vitrectomy for proliferative diabetic retinopathy was done to evaluate the visual outcomes and poor prognostic factors. The surgical results showed that 44(56%) eyes had improved visual acuity. 15(19%) were unchanged, 19(25%) had worse visual acuties. Preoperative factors associated with poor visual outcome include traction or rhegmatogenous retinal detachment. Diabetic duration and renal status had no association with visual outcome. Intraoperative factor associated with a poor visual result include use of intravitreal silicon oil. Postoperative complications associated with poor visual result include iris neovascularization and retinal detachment. |
