The effect of modified Parks incision strabismus correction under the microscope in the treatment of children with horizontal concomitant strabismus and its influence on tear film function

目的探探讨显微镜下改良Parks切口斜视矫正术治疗水平共同性斜视患儿的效果及其对泪膜功能的影响。方法选取我科2017年6月至2019年11月期间95例水平共同性斜视患儿作为研究对象,按照随机数字表法分成两组,均行斜视矫正术,对照组47例给予术中作角膜缘梯形结膜瓣切口,观察组48例给予显微镜下改良Parks切口,1个月后对比两组患儿视功能改善效果、手术效果、泪膜功能。结果观察组治疗后总有效率95.83%高于对照组89.36%(χ^(2)=0.6632,P=0.4154);观察组水平共同性斜视患儿手术时间明显短于对照组(t=11.9892,P=0.0000);观察组患儿治疗后泪液分泌量高于对照组(t=15.0051,P=0.0000),泪膜破裂时间较对照组上升(t=9.2228,P=0.0000),角膜荧光染色评分较对照组降低(t=10.7815,P=0.0000)。结论显微镜下改良Parks切口斜视矫正术治疗水平共同性斜视效果确切,能够显著矫正眼部,改善患儿视功能及泪膜功能,安全可靠,值得应用。

Objective To investigate the effect of modified Parks incision strabismus correction under the microscope in the treatment of children with horizontal strabismus and its influence on tear film function.Methods From June 2017 to November 2019 in our department,95 children with horizontal concomitant strabismus were selected as the research objects,and they were divided into two groups according to the random number table method,all underwent strabismus correction surgery,and 47 cases in the control group received intraoperative surgery.The limbal trapezoidal conjunctival flap incision was performed.48 cases in the observation group were given a modified Parks incision under a microscope.One month later,the visual function improvement effect,surgical effect and tear film function of the two groups were compared.Results The total effective rate of observation group was 95.83% higher than that of control group 89.36%(χ^(2)=0.6632,P=0.4154).The operation time in the observation group was significantly shorter than that in the control group(t=11.9892,P=0.0000).After treatment,the tear secretion in observation group was higher than that in control group(t=15.0051,P=0.0000),the tear film rupture time was higher than that in control group(t=9.2228,P=0.0000),and the corneal fluorescence staining score was lower than that in control group(t=10.7815,P=0.0000).Conclusion The modified Parks incision strabismus correction surgery under the microscope has a definite effect in the treatment of common strabismus.It can significantly correct the eyes and improve the visual function and tear film function of children.It is safe and reliable and worthy of application.
