Two-port pars plana vitrectomy surgery: A prospective interventional case series

Abstract

Background: and objective: Current literature review fails to disclose any series describing the use of two-port vitrectomy in adult patients. This study was performed to determine the feasibility and efficacy of pars plana vitrectomy surgery using two (rather than three or four)-port access for treatment of diabetic patients with nonclearing vitreous haemorrhage due to retinal neovascularization. Design: Interventional prospective case series: to measure ability to allow for long-term resolution of chronic uncomplicated vitreous haemorrhage in diabetic patients, and to study the frequency and nature of complications associated with this technique. Methods: Two-port pars plana vitrectomy (with endolaser treatment and membrane delamination if necessary) was performed in a prospective series of 12 consecutive diabetic patients with nonclearing vitreous haemorrhage due to retinal neovascularization. Results: Successful removal of vitreous haemorrhage resulted in all patients. No visually significant intraoperative complications occurred. Best postoperative visual acuity correlated with lenticular and macular perfusion status. Conclusion: Two-port pars plana vitrectomy is an efficient (and potentially safer and faster) alternative to the standard three-port vitrectomy in selected patients. © 2005 Nature Publishing Group All rights reserved.
