To evaluate the safety and efficacy of four-port bimanual 23-gauge vitrectomy for patients with tractional retinal detachment (TRD) in severe PDR versus three port
twenty eyes of 20 patients who underwent primary vitrectomy for severe diabetic TRD. Ten eyes of 10 cases that were treated with four-port 23-gauge vitrectomy were compared with 10 eyes of 10 cases that were treated with three-port 23-gauge pars plana vitrectomy (PPV). Main outcome measures were best-corrected visual acuity (BCVA), retinal status, intraocular pressure, and incidence of intraoperative and postoperative complications with at least 6 months of follow-up.
The primary and ultimate anatomic success rates (94.4% versus 93.3%, and 100% in both groups, respectively) and the mean BCVA changes did not differ significantly between groups. The whole surgical time and the membrane removal time were significantly (p < 0.001, respectively) shorter in the four-port 23-gauge group than in the three-port 23-gauge group. There was no difference in the incidence of intraoperative and postoperative complications in both groups.
Three-port bimanual 23-gauge vitrectomy offers comparable anatomic success and shortens the surgical time compared with four-port 23-gauge PPV in patients with TRD resulting from severe PDR.
