彩色多普勒超声检查对斜视术后眼血流动力学评价

Evaluation of Hemodynamic Changes in the Ophthalmic Artery with Color Doppler Ultrasonography After Strabismus Surgery

目的：研究彩色多普勒超声检查对斜视术后眼血流动力学改变评价。方法：收集我院2002年5月～2003年10月收治的6～21岁斜视手术患者29例（手术组），分别于术前、术后1周、术后1个月测量眼动脉血流动力学改变，并与同年龄正常者（对照组）进行比较。结果：眼动脉血流参数，手术组术前与对照组各参数比较无明显差异；手术组术前与术后1周各参数比较有明显差异（P〈0．05），与术后1个月各参数比较无明显差异。视网膜中央动脉血流参数，手术组和对照组术前、术后1周及术后1个月比较各参数均无明显差异。结论：同侧眼行斜视（2条水平直肌）手术，术后1周出现眼动脉痉挛，而视网膜中央动脉速度正常，提示斜视手术切断2斧水平直肌可影响眼的动脉血流。

Objective：To evaluate the hemodynamic changes in the ophthalmic artery after strambismus surgery with color Doppler ultrasonographg. Methods：29 strabismus patients age 6 to 21 years old underwent strabismus surgery were included in this study. The hemodynamic changes in the ophthalmic artery were evaluated before surgery,a week after surgery and a month after surgery respectively and were compared to the control group（ same aged normal people）. Results：Before surgery,there were no differences in hemodynamic parameters of ophthalmic artery between strabismus patients and normal people,But there were significant differences in hemodynamic parameters before and one week after surgery in patients with strabismus surgery （P 〈 0.05 ） , however, there were no differences one month after surgery; No differences in hemodynamic parameters of central retinal artery between normal people and stradismus patients before surgery,a week after surgery,and a month after surgery. Conclusion：Operating on two level rectus muscle of eyes at the same sides, ophthalmic artery presents spasming after one week, but central retinal artery velocity is also normal,This study suggest strabismus surgery can effect the blood flouing of ophthalmic artery.
