The authors determined the anatomic and visual success rates of vitrectomy in patients who have failed previous macular hole surgery.
Standardized Early Treatment Diabetic Retinopathy Study (ETDRS)-style best-corrected visual acuity was measured in each patient pre- and postoperatively. Surgery was performed at two centers using a standardized protocol, as previously reported, using 1330 ng bovine-derived transforming growth factor-beta 2 (TGF-beta 2) and 16% perfluoropropane internal gas tamponade. Endpoint analyses were conducted for anatomic closure of the hole, visual improvement of three or more ETDRS lines, and final visual acuity of > or = 20/63 and > or = 20/40.
Forty-eight failing macular hole surgery were reoperated. The anatomic results showed closure of the hole in 40 (83%) cases at the end of the mean follow-up interval of 7.4 months. The visual acuity improved in greater than or equal to three lines in 52%, was > or = 20/63 in 54%, and was > or = 20/40 in 25% of reoperated eyes. The only factor associated with a better final visual acuity was preoperative visual acuity better than 20/80. Nuclear sclerosis leading to cataract extraction was observed in 13 (30%) of 43 initially phakic eyes.
Macular hole closure was induced in this subset of reoperated patients. Visual improvement occurred often, although in a lower percentage than has been reported for primary surgical eyes. Repeat vitrectomy should be considered in patients with persistent macular hole after failure of primary surgery.
作者确定了既往黄斑裂孔手术失败患者玻璃体切除术的解剖学成功率和视力成功率。
在每位患者术前和术后测量标准化的糖尿病视网膜病变早期治疗研究(ETDRS)式最佳矫正视力。手术在两个中心按照标准化方案进行,如先前报道,使用1330 ng牛源性转化生长因子-β2(TGF-β2)和16%的全氟丙烷内气体填塞。对裂孔的解剖学闭合、视力提高三个或更多ETDRS行以及最终视力≥20/63和≥20/40进行终点分析。
48例黄斑裂孔手术失败的患者接受了再次手术。解剖学结果显示,在平均7.4个月的随访期结束时,40例(83%)裂孔闭合。再次手术的眼中,52%的患者视力提高了≥3行,54%的患者视力≥20/63,25%的患者视力≥20/40。与更好的最终视力相关的唯一因素是术前视力优于20/80。在43例最初有晶状体的眼中,有13例(30%)观察到核硬化导致白内障摘除。
在这组再次手术的患者中诱导了黄斑裂孔闭合。视力改善经常出现,尽管比例低于原发性手术眼的报道。对于原发性手术失败后持续性黄斑裂孔的患者,应考虑重复玻璃体切除术。
