23-gauge vitrectomy in 100 eyes: short-term visual outcomes and complications.Retina. 2008 Oct; 28(9):1193-200.R
PURPOSE
To report the short-term outcomes and complications of patients undergoing 23-gauge transconjunctival sutureless pars plana vitrectomy.
METHODS
Retrospective, consecutive, noncomparative case series in which 100 eyes of 100 patients underwent elective 23-gauge pars plana vitrectomy for a variety of surgical indications. All patients were examined on postoperative day 1 and then approximately 1 and 4 weeks later. Demographic and ophthalmic data were recorded.
RESULTS
Fifty-two men and 48 women (mean age = 65 years) were observed for a mean of 26 weeks. Mean preoperative visual acuity was 20/842 and mean final postoperative visual acuity was 20/429. Postoperative visual acuity improved in 68% of patients, worsened in 16%, and remained unchanged in 16%. Mean preoperative intraocular pressure was 15 mmHg and mean postoperative intraocular pressure at final visit was 14 mmHg. No sutures were required to close sclerotomies and no intraoperative complications were observed, though one eye required conversion to 20-gauge pars plana vitrectomy during silicone oil removal. Postoperative complications included retinal detachment, cataract progression, vitreous hemorrhage, persistent macular hole, new macular hole, phthisis, posterior capsular opacification, and severe chemosis.
CONCLUSIONS
Twenty-three-gauge pars plana vitrectomy demonstrates short-term visual outcomes and complication rates that are comparable to those reported with 20- and 25-gauge systems.
