To report the short-term outcomes and complications of patients undergoing 23-gauge transconjunctival sutureless pars plana vitrectomy.
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.
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.
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.
报告接受23G经结膜无缝合扁平部玻璃体切除术患者的短期疗效及并发症。
回顾性、连续性、非对照病例系列研究，100例患者的100只眼因各种手术指征接受了择期23G扁平部玻璃体切除术。所有患者在术后第1天接受检查，然后分别在术后约1周和4周接受检查。记录人口统计学和眼科数据。
观察了52例男性和48例女性（平均年龄65岁），平均观察时间为26周。术前平均视力为20/842，术后最终平均视力为20/429。68%的患者术后视力提高，16%的患者视力下降，16%的患者视力无变化。术前平均眼压为15 mmHg，末次随访时术后平均眼压为14 mmHg。无需缝合巩膜切口，术中未观察到并发症，不过有1只眼在硅油取出过程中需要转换为20G扁平部玻璃体切除术。术后并发症包括视网膜脱离、白内障进展、玻璃体积血、持续性黄斑裂孔、新发性黄斑裂孔、眼球痨、后囊膜混浊和严重球结膜水肿。
23G扁平部玻璃体切除术的短期视力疗效和并发症发生率与20G和25G系统报道的结果相当。
