Outcomes of 27 Gauge Microincision Vitrectomy Surgery for Posterior Segment Disease

Abstract

Purpose To report the initial experience, clinical outcomes, and safety profile of 27 gauge pars plana vitrectomy (PPV) in eyes with posterior segment disease. Design Multicenter, retrospective, interventional case series. Methods setting: Private practice and tertiary care settings. study population: Eyes undergoing 27 gauge PPV for a vitreoretinal surgery indication. intervention: Three-port, transconjunctival 27 gauge PPV. main outcome measures: Change in visual acuity and occurrence of intraoperative and postoperative complications with minimum follow-up of 90 days. Results Ninety-five eyes met the inclusion criteria. Surgical indications included epiretinal membrane (n = 26), diabetic tractional retinal detachment (n = 14), full-thickness macular hole (n = 11), rhegmatogenous retinal detachment with (n = 7) or without (n = 9) proliferative vitreoretinopathy (PVR), vitreous hemorrhage (n = 10), vitreous opacities (n = 8), endophthalmitis (n = 4), sub–silicone oil retinal detachment (n = 3), retained lens material (n = 1), submacular hemorrhage (n = 1), and aqueous misdirection (n = 1). Mean logMAR visual acuity improved from 1.08 ± 0.71 (20/240 Snellen equivalent) preoperatively to 0.53 ± 0.65 (20/67 Snellen equivalent) postoperatively ( P Conclusion The 27 gauge PPV was well tolerated with low rates of intraoperative and postoperative complications across varied surgical indications.
