对１５２例无晶体眼硅油填充术后出现硅油入前房的原因进行统计学分析并提出了处理意见。方法：１９９３年９月至１９９６年３月我院进行的１５２只无晶体眼硅油填充术后，随诊至少半年或至硅油取出，详细记录眼压、虹膜和下方周边虹膜切除情况、硅油位置以及视网膜情况。用卡方检验对相关因素进行统计学分析。结果：１５２只无晶体硅油填充术眼中有２１只眼硅油前移入前房（１３．８％），由于ＩＰＩ关闭所致者１４只眼（占６６．７％），眼压低者３只眼，无虹膜者３只眼。一旦发生ＩＰＩ关闭，７３．７％（１４／１９）发生硅油前移，而ＩＰＩ保持通畅者硅油前移的发生率很低（３．１％）。结论：ＩＰＩ关闭是无晶体眼硅油填充术后硅油前移的主要原因，因此保持ＩＰＩ的通畅至关重要
A total of 152 cases of aphakic silicone oil filling after the occurrence of silicone oil into the anterior chamber for statistical analysis and put forward the views of treatment. Methods: From September 1993 to March 1996, 152 patients with aphakic eye silicone oil filled in our hospital were followed up for at least six months or until the silicone oil was removed. The intraocular pressure, the iris, the iris around the lower part, the location of the silicone oil, Retina conditions. Using chi-square test for statistical analysis of relevant factors. RESULTS: Twenty-one of the 152 eyes without silicone oil-filled eyes advanced into the anterior chamber (13.8%) due to IPI closure, 14 eyes (66.7%) due to IPI closure, and 3 eyes with low intraocular pressure No iris 3 eyes. In the event of IPI closure, silicone oil advancement occurred in 73.7% (14/19) and silicone oil advancement was minimal (3.1%) in IPI. CONCLUSIONS: IPI closure is the primary cause of silicone oil advancement after aphakic silicone oil-filled surgeries, so it is crucial to maintain the patency of IPI
