| 【摘要】 目的 评价外伤性睫状体离断复位手术后眼压（IOP）的动态变化趋势，为术后眼压的临床观察和处理提供定量依据。方法：回顾分析了2001年1月—2007年1月在本中心的单纯外伤性睫状体离断病例共108人108眼，均进行了直接缝合复位手术，手术后眼前房加深稳定。记录分析自术后第1、2、3、4、5、6、7、14天，共8个时间点的眼压，并根据上述各点的眼压值，将随访病例分为三组：（1）低眼压组：<10mmHg；（2）正常眼压组：10-21mmHg；（3）高眼压组：>21mmHg。同时，记录手术后1-3天各个组病例的断离范围和伤后时间。统计分析上述各组病例在以上8个时间点的构成比分布特征，以及手术后3天内断离范围和伤后时间与眼压变化的关系。结果：手术后第1、2、3天，低眼压组的百分比分别是10.2%，14.9%，15.9%；断离范围分别是3.5，4.0，3.3个钟点；受伤时间分别是30，60，30天。正常眼压组的百分比分别是17.6%，52.5%，72.7%；断离范围分别是4.0，3.0，3.0个钟点；受伤时间分别是60，45，50天。高眼压组的百分比分别是的百分比分别是72.2%，32.7%，11.4%；断离范围分别是3.5，2.8，3.0个钟点；受伤时间分别是42，60，45天。手术后第4-14天期间，低眼压组的百分比范围1.9%—8.3%，平均为2.4%；正常眼压组的百分比范围80.8%—88.9%，平均为86.9%；高眼压组的百分比范围2.8%—11.5%，平均为7.3%。结论：手术后眼压呈动态变化，最大的变化发生在手术后3天内。第4天到第14天，90%的病例眼压可恢复正常。第7—14天之间，各个组眼压分布保持平稳。受伤时间和断离范围与眼压变化无关。
【Abstract】 Objective To invest the dynamic changes of postoperative intraocular pressure of cyclopexy on cyclodialysis. Patients and methods: Retrospectively analyzed 130 cases of cyclodialysis. Cyropexy were performed, intraocular pressure were measured daily in the first postoperative week, and the second week.. All cases were divided into 3 groups based on the IOP value: (1) hypotension group; (2) normal tension; (3) hypertension group, the characteristics of IOP distribution over the two postoperative weeks were analyzed. Results: During the period of the first to third day postoperatively, （1）hypotension group: the percentage of hypotension cases are 10.2%，14.9%，15.9% respectively；extension of cyclodialysis are 3.5, 4.0, 3.3 clocks respectively; post-traumatic duration are 30, 60, 30 days respectively. (2)normal tension group: the percentage of normal tension case are 17.6%，52.5%，72.7% respectively；extension of cyclodialysis are 4.0, 3.0, 3.0 clocks respectively; post-traumatic duration are 60, 45, 50 days respectively. (3)hypertension group: the percentage of hypertension case are 72.2%，32.7%，11.4% respectively; extension of cyclodialysis are 3.5, 2.8, 3.0 clocks respectively; post-traumatic duration are 42, 60, 45 days respectively. During period of 4-14 days postoperatively, the range of the percentage of hypotension is 1.9%-8.3%, the average value is 2.4%；the range of percentage of normal tension is 80.8%-88.9%, the average value is 86.9%; the range of percentage of hypertension is 2.8%-11.5%, the average value is 7.3%. Conclusions: Dynamic changes of IOP have been observed after cyclopexy, the greatest postoperative change of IOP occurs in the first 3 days. After the third day, normal IOP can be observed in 90% cases, and IOP values remain unremarkable variation in each group. No statistic correlation between IOP change and extension and post-traumatic duration were observed.
