摘要
目的探讨影响共同性内斜视手术正位率的因素。方法46例共同性内斜视患者按麻醉方式、年龄、病程、斜视度数分组,术前检查包括屈光状态、视力、斜视角测定和牵拉试验。术后对各组正位率进行统计学分析。结果46例患者1次治愈35例,未愈11例。全身麻醉组和表面麻醉组正位率分别是76.19%和76.00%,2组比较差异无统计学意义(χ2=0.0025,P>0.05);2～7岁、8～14岁、≥15岁3组的正位率分别是83.33%、78.57%、70.00%,3组间的差异均无统计学意义(Hc=0.7836,P>0.05);病程≤5a组、6～10a组、≥11a组的正位率分别是88.89%、64.29%、71.43%,3组间差异均无统计学意义(Hc=2.9989,P>0.05);10△～35△组、36△～60△组、≥61△组正位率分别是92.31%、84.21%、50.00%,3组间差异有统计学意义(Hc=7.6357,P<0.05),其中低、中度数组间差异无统计学意义(H=0.6400,P>0.05),但它们和高度数组间差异有统计学意义(H=2.3300和2.0600,P均<0.05)。结论共同性内斜视手术正位率与麻醉方式、年龄、病程无主要关系,斜视度是影响其术后正位率的主要因素。
Objective To explore the factors affecting the postoperative orthotopic ratio of concomitant esotropia. Methods Forty-six cases were divided into several groups by the ways of anesthesia, age differences, courses and strabismus degree. Preoperative examination include refractive condition, visual acuity, determination of angle of strabismus and distraction test. Postoperative orthotopic ratio was compared and statistically analyzed among different groups. Results Thirty-five cases（75.09% ） were cured,but ll cases（23.91% ） were not. The postoperative orthotopic ratio of general anesthesia and topical anesthesia were 76. 19% and 76.00%, respectively, and no significant difference was found between the two groups（χ^2 = 0. 002 5 ,P 〉 0.05 ） ;The orthotopic ratio of patients with 2 to 7 years old group, 8 to 14 years old group and group aged more than 15 years old were 83.33% ,78.57% and 70.00% ,respectively,and there was no significant difference among them（ Hc = 0.783 5 ,P 〉 0.05 ） ;The orthotopic ratio of group with course more than 5 years,group with 6 to 10 years and group with more than 11 years were 88.89% ,64.29% and 71.43% ,respectively,and there was no significant difference among them （ Hc = 2. 998 9, P 〉 0. 05 ） ; The orthotopic ratio of group with strabismus degree from 10 to 35,36 to 60 and more than 51 prism diopter were 92.31% ,84.21% and 50.00% ,respectively,and there was no significant difference between the former two groups（H = 0.640 0 ,P 〉0.05 ） ,but there was significant difference for each of former two groups compared with the last group （ H = 2. 330 0 and 2. 060 0,both P 〈 0. 05 ）, and significant difference was also found among these three groups（He = 7. 535 7 ,P 〈 0.05 ）. Conclusion Strabismus degree is the mainly factor affecting postoperative orthotopic ratio, while the ways of anesthesia, age differences and courses are not.
