To report the effectiveness and safety of primary 23-Gauge (G) vitreoretinal surgery for rhegmatogenous retinal detachment (RRD).
In this retrospective study, 49 eyes of 49 consecutive patients who underwent primary 23-G transconjunctival sutureless vitrectomy (TSV) for RRD between January 2007 and July 2009 at our institution were evaluated.
Mean follow-up time was 8.9±7.7 months (1-28 months). Retinal reattachment was achieved with a single operation in 47(95.9%) of 49 eyes. In two eyes (4.1%), retinal redetachment due to new breaks was successfully treated with reoperation using the 23-G TSV system. Mean logMAR visual acuity was 2.01±0.47 preoperatively and 1.3±0.5 postoperatively (P<0.001, Paired t-test). Mean preoperative intraocular pressure (IOP) was 14.1±2.8mmHg. Mean postoperative IOP was 12.3±3.6mmHg at 1 day, 13.1±2.1mmHg at 1 week, 14.3±2.2mmHg at 1 month. Iatrogenic peripheral retinal break was observed in 1 eye (2.0%) intraoperatively. No sutures were required to close the scleral or conjunctival openings, and no eyes required convertion of surgery to 20-G vitrectomy.
Primary 23-G TSV system was observed to be effective and safe in the treatment of RRD.
报告23G原发性玻璃体视网膜手术治疗孔源性视网膜脱离（RRD）的有效性和安全性。
在这项回顾性研究中，对2007年1月至2009年7月期间在我院接受23G原发性经结膜无缝合玻璃体切除术（TSV）治疗RRD的49例连续患者的49只眼进行了评估。
平均随访时间为8.9±7.7个月（1 - 28个月）。49只眼中有47只（95.9%）通过单次手术实现视网膜复位。2只眼（4.1%）因新裂孔导致视网膜再脱离，使用23G TSV系统再次手术成功治疗。术前平均logMAR视力为2.01±0.47，术后为1.3±0.5（P<0.001，配对t检验）。术前平均眼压（IOP）为14.1±2.8mmHg。术后1天平均IOP为12.3±3.6mmHg，1周时为13.1±2.1mmHg，1个月时为14.3±2.2mmHg。术中1只眼（2.0%）观察到医源性周边视网膜裂孔。无需缝合关闭巩膜或结膜切口，也无眼需要将手术转换为20G玻璃体切除术。
观察到原发性23G TSV系统治疗RRD有效且安全。
