在检查双眼眼球运动情况时,各条眼外肌功能亢进与不足程度的分级标准很难确定。分级标准的不统一,直接导致研究结果缺乏可比性。眼外肌功能亢进与不足程度的判定在斜视的分类诊断和设计手术时的肌肉选择中具有重要意义,如对于A征外斜视患者,其上斜肌是否亢进及其程度是决定手术 In examining the case of eye movement, the extraocular muscle function hyperthyroidism and the extent of the grading standards is difficult to determine. The non-uniformity of grading standards directly leads to the lack of comparability of research results. Extraocular muscle function hyperthyroidism and the degree of judgment in the classification of strabismus and the design of surgical muscle selection is of great significance, such as A exotropia patients, the upper oblique is hyperthyroidism and its extent is determined by surgery
