目的:观察水平斜视矫正术对手术眼眼压的影响,为进一步探索眼前节血液流量和眼压的相关性研究提供依据。方法:将46例70眼斜视患者分为两部分,其中55眼实施一条水平直肌矫正手术,另15眼实施两条水平直肌矫正手术。对所有手术眼用CanonTX-F非接触眼压计测量眼压,测量眼压的时段为术前1～2d、术后第1d、术后1wk、术后1mo、术后3mo5个时段。将两部分测量数据整理后进行方差分析。结果:两部分手术眼的平均眼压值从术前到术后短期都有一个升高的过程,到术后1mo眼压平均值逐渐下降,3mo时的眼压平均值最低。实施一条水平直肌矫正手术的55眼,术前眼压均值分别和术后第1d、术后1wk眼压均值相比,差异无统计学意义;但和术后1mo的眼压均值相比,差异有统计学意义(P=0.016);术前眼压均值和术后3mo眼压均值相比,差异也有统计学意义(P=0.006)。15眼实施二条水平直肌矫正手术的部分,术前眼压均值分别和术后第1d、术后1wk、术后1mo、术后3mo眼压均值相比,差异均无统计学意义。结论:斜视眼经过水平直肌矫正术,眼压均值从术前到术后短期都有一个升高的过程,到术后1mo眼压平均值逐渐下降,3mo时的眼压平均值最低。

AIM:To observe the effect of horizontal strabismus surgery on the intraocular pressure(IOP)so as to offer evidence for further exploring the correlation between the change of anterior segment blood flow and IOP.METHODS:Forty-six cases 70 eyes received horizontal strabismus surgery,and were divided into two groups.55 eyes underwent one horizontal rectus muscle surgery,15 eyes underwent two horizontal rectus muscle surgery.All surgical eyes were measured by NCT Canon TX-F at five time stages:preoperative 1-2 day;1 day,1 week,1 month,3 months after operation.Then two groups samples data were analyzed with ANOVA.RESULTS:In the group of one horizontal rectus muscle surgery there were no significant differences between the IOP of preoperation and 1 day postoperatively;preoperation and 1 week postoperatively;while there was significant difference between the IOP of preoperation and 1 month postoperatively(P=0.016);there was significant difference between the IOP of preoperation and 3 months postoperatively(P=0.006).In the group of two horizontal retus muscle surgery the IOP of preoperation had no significant differences with that of 1 day postoperatively,1 week postoperatively,1 month postoperatively and 3 months postoperatively.CONCLUSION:The IOP of eyes undergone horizontal rectus strabismus surgery has a slight rise in both groups,then it gradually decreases.Those of 3 months postoperation are lowest in five time stages.In the group of one horizontal rectus strabismus surgery,there are significant differences between the IOP of preoperation and 1 month postoperatively;preoperation and 3 months postoperatively.
