在眼肌临床上,常用视野计法和遮盖加三棱镜法测量斜视角,前者是测量斜视的圆周度,后者则是测量斜视的三棱镜度。视野计法是根据反光点恰落在角膜中央时灯光在视野计上的所在刻度来确定斜视度;遮盖加三棱镜法则是以三棱镜中和眼球运动来确定斜视度。研究圆周度与三棱镜度的关系,对准确估计斜视度,设计斜视手术量具有重要的临床意义。圆周度与三棱镜度的对比研究在国内尚未见报道。本文就水平斜视的圆周度与三棱镜度的对比进行线性回归分析,求其相关系数和回归系数,并从理论和临床上探求其换算值的数据。
In ophthalmokinesis clinics, the common field of view method and cover plus prism measure oblique angle, the former is to measure the circularity of strabismus, the latter is the measurement of strabismus degree of prism. Horizons method is based on the reflective point just when the cornea at the center of the light in the field of vision on the scale to determine the degree of strabismus; cover plus prisms rule is prism and eye movement to determine the strabismus. To study the relationship between circularity and prisms, it has important clinical significance to accurately estimate the degree of strabismus and design the amount of strabismus surgery. Comparative study of the degree of circularity and prism has not been reported in China. In this paper, the linear regression analysis of the horizontal strabismus degree of the prism and the prism, the correlation coefficient and regression coefficient, and its theoretical and clinical data to explore the conversion value.
