眼球运动快而准确,能发挥眼的视觉功能。双眼的运动要协调,眼球运动交互支配的原则依赖于作用肌的收缩和拮抗肌的同时松弛,例如,向右注视时左眼的内直肌收缩和外直肌放松,同时右眼的外直肌收缩和内直肌放松。如果眼肌和其支配神经出现异常,都可以造成眼球运动失常,眼肌电图能协助分析斜视、复视和眼球运动障碍的部位,可分辨神经源和肌源性疾病,也有助于重症肌无力的诊断。本文检查了正常成人眼20只和息者29人,报道如下。
Eye movement fast and accurate, can play the visual function of the eye. To coordinate the movement of the eyes, the principle of interactive control of the eye movement depends on the contraction of the effector muscle and the simultaneous relaxation of the antagonist muscle. For example, the contraction of the medial rectus muscle of the left eye and the relaxation of the extensor muscle at the time of rightward gaze, Muscle contractions and rectus muscles relax. If the eye and its dominant nerve abnormalities can cause eye movement disorders, oculography can help analyze strabismus, diplopia and ocular motility disorders, can distinguish between neurogenic and myogenic diseases, but also contribute to myasthenia gravis Inability to diagnose. This article examines the normal adult eye 20 and the interest of 29 people, reported as follows.
