To investigate the risk factors associated with suprachoroidal hemorrhage (SCH) during vitrectomy.
Of 6971 pars plana vitrectomies performed between May 1988 and December 1994, SCH occurred intraoperatively in 12 (0.17%) cases. Forty-two age- and sex-matched control subjects were selected by computer-generated random numbers. Preoperative and intraoperative variables were subjected to univariate and conditional logistic regression analysis.
Statistically significant risk factors for SCH after univariate analysis included myopia (P = .048), aphakia or pseudophakia (P = .024), rhegmatogenous retinal detachment (P = .044), scleral buckling and/or encirclage at vitrectomy (P = .029), and longer duration of surgery (P = .044). Multivariate analysis revealed independent risks associated with the absence of a lens and longer duration of the surgery.
A knowledge of the risk factors involved with SCH helps the physician to identify patients who are at a greater risk for this complication.
探讨玻璃体切割术中脉络膜上腔出血（SCH）的相关危险因素。
在1988年5月至1994年12月期间进行的6971例扁平部玻璃体切割术中，有12例（0.17%）术中发生SCH。通过计算机生成随机数选取42例年龄和性别匹配的对照受试者。对术前和术中变量进行单因素及条件逻辑回归分析。
单因素分析后，SCH的统计学显著危险因素包括近视（P = 0.048）、无晶状体或人工晶状体（P = 0.024）、孔源性视网膜脱离（P = 0.044）、玻璃体切割术中巩膜扣带和/或环扎（P = 0.029）以及手术时间较长（P = 0.044）。多因素分析显示与无晶状体和手术时间较长相关的独立危险因素。
了解与SCH相关的危险因素有助于医生识别发生该并发症风险较高的患者。
