  • Title: Two-port pars plana vitrectomy surgery: a prospective interventional case series.
    Author: Colucciello M.
    Journal: Eye (Lond); 2005 Aug; 19(8):869-72. PubMed ID: 15359245.
    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.
