Purpose: To report the safety and efficacy of single-port pars plana anterior vitrectomy.
Setting: Study performed by a single surgeon (MES) at a single institution over a 6-year time span.
Design: This is a retrospective observational chart review of 333 patients (348 eyes) who underwent one-port pars plana anterior vitrectomy.
Methods: Eyes that underwent anterior vitrectomy from September 2010 to June 2016 were electronically identified. Charts were reviewed for demographics, history of ocular trauma, underlying ocular or systemic comorbidity, surgical indications, outcomes and postoperative complications.
Results: The mean postoperative follow-up was 10.9 months with a mean age of 62.4 years old. Three hundred thirty-five eyes (97.7%) were scheduled as planned anterior vitrectomies, while eight eyes (2.3%) were performed unexpectedly after posterior capsular ruptures. Eighty-two eyes (23.9%) had a history of trauma. Twenty-five eyes (7.3%) had documented postoperative CME, while seven of these eyes had known preoperative CME. There were a total of three eyes (0.9%) with retinal detachments and one eye (0.3%) with a retinal tear without detachment. There were no cases of endophthalmitis and no evidence of residual vitreous prolapse in the anterior chamber in any eyes postoperatively.
Conclusions: This study shows that the safety and efficacy profile of the pars plana technique compares favorably against historical data for both coaxial and bimanual limbal clear corneal infusion and cutting. Sutureless pars plana anterior vitrectomy may be considered a safe and reliable solution for the anterior segment surgeon in managing vitreous prolapse during anterior segment surgeries.
