23-gauge pars plana vitrectomy surgery results of the cases with diabetic tractional retinal detachment

Objective: To evaluate the pars plana vitrectomy (PPV) surgery results of the patients with diabetic tractional retinal detachment (TRD).Methods: Two hundred ten eyes of 193 patients with diabetic TRD were enrolled to the study. Patients with TRD underwent 23-Gauge(G) PPV were reviewed retrospectively. All patients’ preoperative and postoperative visual acuity changes, intraocular pressure changes, biomicroscopy, indirect ophthalmoscopy fundus examination, intraoperative and postoperative complications, intraoperative use of tamponade and postoperative period surgical notes were evaluated.Results: Ninety-five males (49.2%), 98 female (50.8%) of 193 patients were included to the study. Mean age was 56.01 ± 10.91 years during the surgery. The average postoperative follow-up period was 18.47 ± 14.06 months. Ninety-seven eyes were performed preoperative intravitreal (IV) bevacizumab injection. Statistically significant increase in the final visual acuity compared to the controls were recorded at 1, 3, 6, 12, 24, 36. months. (p<0.001). Preoperative and postoperative 1st day, 1st month, 6th months, 12th months results were statistically significant according to intraocular pressure (p<0.001). While 201 (95%) cases achieved anatomical success, 165 (78.5%) cases were achieved functional success.Conclusion: PPV is very effective method in providing anatomical and functional outcomes in patients with diabetic TRD. Preoperative intravitreal bevacizumab application is an effective treatment method in reducing intraoperative and postoperative complications, and shorten the operation time.
