【摘要】：目的比较4种常用的隐斜视测量方法的有效性。方法选取西安医学院大学生中存在聚散功能障碍者32人,分别使用Von Graefe法、加遮盖Von Graefe法、Maddox rod法及加遮盖Maddox rod法对各受试者分别进行远距(眼前5m)及近距(眼前40cm)隐斜视的检查。利用Sheard准则或1∶1准则分别计算出由不同隐斜视测量方法所得的l 试验性棱镜处方,调整棱镜度以交替遮盖后眼位运动快速、平滑作为实际棱镜处方的判定标准。统计分析各种方法所得试验性棱镜处方与实际棱镜处方之间的差异,评价各种隐斜视测量方法的有效性。结果远距隐斜视测量值Von Graefe法(-14.594△±2.513△)较Maddox rod法(-13.562△±2.449△)更偏外隐斜(P=0.000),近距隐斜视测量值Maddox rod法(-14.906△±6.198△)较Von Graefe法(-14.469△±6.461△)更偏外隐斜(P=0.011)。Von Graefe法、加遮盖Von Graefe法、Maddox rod法及加遮盖Maddox rod法试验性棱镜处方分别为3.984△±1.417△、4.516△±1.459△、3.500△±1.391△、4.297△±1.453△,其中Von Graefe法所得试验性棱镜处方与实际棱镜处方(3.936△±1.441△)的相关性最高(r=0.979,P=0.000),且二者间的差异不具有统计学意义(P=0.374);其余3种方法与实际棱镜处方的相关程度由高到低依次为加遮盖Von Graefe法(r=0.952,P=0.000)、加遮盖Maddox rod法(r=0.945,P=0.000)及Maddox rod法(r=0.937,P=0.000)。结论不配合遮盖的Von Graefe法与实际棱镜处方的相关性最强,其有效性最好。
[Abstract]:Objective to compare the effectiveness of four common methods for the measurement of esotropia. Methods 32 college students in Xi'an Medical College were selected to use Von Graefe method. The covered Von Graefe method, Maddox rod method and covered Maddox rod method were used to examine the distance (5 m) and the short distance (40 cm) of the subjects, respectively. By using the Sheard criterion or 1: 1 criterion, the authors calculated the results of different methods of measuring esotropia. L experimental prism prescription, Adjusting the prism degree to cover the eye position quickly and smoothly is the criterion of the actual prism prescription. The difference between the experimental prism prescription and the actual prism prescription obtained by various methods is analyzed statistically. Results compared with Maddox rod method (-13.562 卤2.449), Von Graefe method was more effective than Maddox rod method in measuring esotropia. Maddox rod method was 14.906 卤6.198, and Von Graefe method was 14.469. 卤6.461), and the method of Pen 0.011 + Von Graefe, The experimental prism prescriptions of covered Von Graefe method and covered Maddox rod method were 3.984 卤1.417 卤4.516 卤1.459 卤3.500 卤1.391 卤4.297 卤1.453, respectively. The correlation between the experimental prism prescription and the actual prism prescription obtained by Von Graefe method was the highest. The correlation between the experimental prism prescription and the actual prism prescription was the highest, and the difference between the two methods was not statistically significant. The correlation degree between the other three methods and the actual prism prescription was higher than that of the actual prism prescription. The lower order was Von Graefe (0.952), Maddox rod (0.945) and Maddox rod (0.937 P0.000). Conclusion the correlation between Von Graefe and prism prescription is strongest. Its effectiveness is the best.
