Outcomes of Pars Plana Vitrectomy for Diabetic Tractional Retinal Detachment in a Tertiary Care Hospital of Peshawar

Purpose:  To determine the visual outcomes of Pars Plana Vitrectomy (PPV) in eyes with diabetic tractional retinal detachment (TRD) in a tertiary care center of Peshawar. Study Design:  Interventional case series. Place and Duration of Study:  Department of Ophthalmology, Hayatabad Medical Complex (HMC), Peshawar for 06 months duration. Methods:  Total of 39 patients diagnosed with TRD secondary to Proliferative Diabetic Retinopathy(PDR)were enrolled. All patients underwent standard 23-gauge vitrectomy. Snellen chart was used to evaluate the preoperative and postoperative Best-Corrected Visual Acuity (BCVA). Results:  The average age of patients was 55.2 ± 8.4 years, with all cases having type II diabetes and a mean disease duration of 11.2 ± 3.8 years. Preoperatively, only 3% patients had BCVA of 6/24 or better, whereas postoperatively, 39% achieved this visual acuity. A significant visual improvement was observed in 72% of patients, with 10% reaching 6/18 and 3% achieving 6/12. On log-MAR scale, the visual acuity improved from 1.33±0.38 before vitrectomy to 0.97±0.41 after Vitrectomy (p < 0.0001). Conclusion:  In this prospective case series, most patients demonstrated meaningful postoperative visual gain, with a substantial increase in the proportion achieving functional vision. The significant improvement in LogMAR visual acuity highlights the role of timely PPV in eyes with TRD secondary to proliferative diabetic retinopathy, even in patients with long-standing type II diabetes.
