212 Outcomes Of 25-Gauge Pars Plana Vitrectomy Surgery in Primary Rhegmatogenous Retinal Detachment in Pakistan: A Multi-Center Study

Abstract

Abstract Aim To evaluate the primary anatomical success and visual outcomes in patients with rhegmatogenous retinal detachment (RRD) undergoing 25-gauge pars plana vitrectomy (25g PPV) surgery in Pakistan. Method This is a five-year retrospective, interventional cohort study of 418 consecutive patients with RRD who underwent 25g PPV. Surgeries were performed by two experienced surgeons at tertiary care hospitals in Pakistan. Consecutive patients, who underwent 25 g PPV surgery as treatment for RRD between October 2013-October 2018 were included. We excluded patients who had a history of previous retinal surgery or who did not complete the 4-8 weeks primary outcome visit. Data was collected from the patient’s files by using a pro forma. SPSS version 23.0 (IBM SPSS Statistics, Armonk, NY) was used. A p-value of < 0.5 was considered significant. Results We identified 452 patients through coding system of hospitals who underwent 25g PPV surgery between October 2013-October 2018. Secondary retinal surgery and incomplete follow up cases were excluded. A total of 441 patients’ files were reviewed for the study, out of which 418 patients met the criteria for final analysis. Males were in a higher number 284 (67.9 %). The average age was 49±15.8. In our study, 186 (44.4%) patients were phakic at the time of presentation. At 2 months follow up, the primary anatomical success rate was 87.1 %. Conclusions Surgical outcomes of RRD with 25g PPV surgery in our study were similar to the outcomes reported in the developed world. We propose a prospective multicenter national study to prospectively evaluate the risk factors for RRD surgical failure in the Pakistani population.
