近年来国外对外斜视的原因及治疗提出了新的理论。指出外斜视的主要原因是由于主眼(即注视眼)有一种异常的持续性的神经冲动传至从眼(斜视眼)的外直肌,使该肌收缩而引起外斜视。试验让主眼向内转对侧眼即内转,向外转对侧眼即外转的现象称逆位相眼球反射。前者引起斜视眼外直肌高度弛缓,后者引起斜视眼外直肌高度收缩。肌电图证实了上述情况。根据上述原理对主眼行手术矫正,术后不但外斜视眼眼位得到矫正,同时恢复了融合、辐辏及立体视功能、弱视眼的视力也得到提高。但对小度数的外斜视眼手术矫正的选择,是否
In recent years, the causes of external strabismus and treatment proposed a new theory. Pointed out that the main reason for exotropia is due to the main eye (ie, gaze) there is an abnormal sustained nerve impulse transmitted from the eye (strabismus) of the lateral rectus, the contraction of the muscle and cause exotropia. The test allows the main eye to turn to the opposite side of the eye that the internal rotation, outward turn to the contralateral eye that is the phenomenon of the outer turn called reverse phase reflex. The former caused by strabismus external rectus height flaccid, the latter caused by strabismus external rectus muscle contraction. EMG confirmed the above situation. According to the principle of the main line of eye surgery, postoperative not only exotropia eye position correction, and restore fusion, convergence and stereo vision function, visual acuity also improved amblyopic eyes. But the small degree of exotropia surgery correction options, is it
