目的：探讨219例23口径无缝线平坦部玻璃体切除术中巩膜渗漏的危险因素。方法：采用嵌套病例对照研究方法，对48例伤口渗漏患者(可见的台上巩膜渗漏需要缝合)和171例对照组进行对照研究。患者接受常规巩膜切开45度，然后改为90度中切口，或极斜巩膜切开(OSI)10度，然后改为30度中切口。研究的危险因素包括年龄、性别、偏侧性、手术时间、巩膜切开切口(OSI与常规巩膜切开)、术前诊断(黄斑与非黄斑)、玻璃体切除病史、初级外科医生(主治医师与住院医师)。
Purpose: To evaluate risk factors for sclerotomy leakage in 23-gauge sutureless pars plana vitrectomy in 219 patients.Methods: Nested case-control study involving 48 patients with wound leaks (visible on-table sclerotomy leakage requiring sutures) and 171 control subjects without wound leaks. Patients received either a conventional sclerotomy incision at 45 degrees, which was then changed to 90 degrees midincision, or an extremely oblique sclerotomy incision (OSI) at 10 degrees, which was then changed to 30 degrees midincision. Risk factors studied included age, gender, laterality, surgical duration, sclerotomy incision (OSI vs. conventional sclerotomy incision), pre-operative diagnosis (macular vs. nonmacular), history of vitrectomy, and primary surgeon (attending vs. supervised resident).Results: Multivariate logistic regression analysis found significant (P
