用压迫法降低眼压,观察眼压降低的程度以帮助诊断,早已有大量的文献报道。但利用此法帮助手术,减少并发症,则未见系统综述。本文拟对这方面的文献进行一些复习,而不涉及其诊断方面的资料。白内障摘出术中玻璃体脱出是一种严重的并发症。尽管目前对玻璃体脱出应用前部玻璃体切除术可以减少其后果的危害性,但最好还是能预防玻璃体的脱出。尤其是在白内障手术植入人工晶体时,更应避免玻璃体脱出的发生。术前应用镇静剂、醋氮酰胺、高渗剂都可降低眼压,及有助于防止玻璃体脱出。但这些方法对全身有一定的副作用,甚至在某些患者是禁忌使用的。而术前压迫眼球,则是一种比较简单易行、安全有效的降低眼压的方法。用压迫法降低眼压,应用于白内障手术已有长期的历史。尤其在最近开展人工晶体手术以来,更得到广泛的采用与许多新的改 With the oppression method to reduce intraocular pressure, observe the degree of intraocular pressure to reduce the extent to help diagnose, has long been a large number of literatures. However, the use of this method to help surgery and reduce complications, there is no systematic review. This article intends to some review of this literature, but not related to the diagnostic information. Cataract extraction during vitreous prolapse is a serious complication. Although the current application of anterior vitrectomy for vitreous prolapse can reduce the harm of its consequences, it is best to prevent the vitreous prolapse. Especially in cataract surgery intraocular lens implantation, the occurrence of vitreous prolapse should be avoided. Preoperative application of sedatives, acetamide, hypertonic agents can reduce intraocular pressure and help prevent vitreous prolapse. However, these methods have some side effects on the whole body and are contraindicated even in some patients. Preoperative oppression of the eye, it is a relatively simple, safe and effective way to reduce intraocular pressure. With oppression to reduce intraocular pressure, used in cataract surgery has a long history. Especially in the recent intraocular lens surgery has been more widely used and many new changes
