METHODS: In this retrospective study, 1020 consecutive surgeries were performed on 958 eyes of 848 patients using 27-gauge instruments from March 2017 to June 2021. Patients with a minimum follow-up of 3 months were included. Surgical case-mix, best-corrected visual acuity (BCVA), intraocular pressure (IOP), intra- and post-operative complications, and surgery times were recorded.
RESULTS: The study patients were followed up for averagely 11 months. Of the 1020 vitrectomies, 958 were primary procedures. Of the 148 retinal detachment (RD) cases, 138 (93%) required a single vitrectomy. Primary macular hole closure was achieved in 143 of 145 (99%) cases. The average surgical times were 55 and 38 min for RD surgeries and for all other indications, respectively. BCVA improved significantly at the final visit (20/49) compared with the pre-operative visit (20/78) (p < 0.01). IOP was similar at the pre-operative (14.8mmHg) and final (14.3mmHg) visits. Complications recorded include transient hypotony in 39 eyes, iatrogenic retinal breaks in 2 eyes, and a vitreous bleed in 1 other eye.
CONCLUSIONS: This study revealed that 27-gauge vitrectomy instruments can be used for a wide range of indications, with exclusive use in certain settings. The outcomes were similar to other gauges, including for rhegmatogenous retinal detachment, with minimal complications.
方法:在这项回顾性研究中,从2017年3月至2021年6月,使用27号仪器对848名患者的958只眼睛进行了1020次连续手术。纳入最少随访3个月的患者。外科病例混合,最佳矫正视力(BCVA),眼内压(IOP),术中和术后并发症,并记录手术时间。
结果:本研究患者平均随访11个月。在1020例玻璃体切除术中,958是主要程序。在148例视网膜脱离(RD)中,138例(93%)需要一次玻璃体切除术。145例中的143例(99%)实现了原发性黄斑裂孔闭合。RD手术和所有其他适应症的平均手术时间为55和38分钟。分别。与术前访视(20/78)相比,最终访视时的BCVA显着提高(20/49)(p<0.01)。术前(14.8mmHg)和最终(14.3mmHg)就诊时的眼压相似。记录的并发症包括39只眼的短暂性低眼压,2只眼的医源性视网膜破裂,还有一只眼玻璃体出血.
结论:这项研究表明,27号玻璃体切割器械可用于多种适应症,在某些设置中独占使用。结果与其他量表相似,包括孔源性视网膜脱离,最小的并发症。
