We report three patients with a rare variant of Duane's retraction syndrome.
Eye movements were recorded by electro-oculography. One patient underwent electro-myography.
All patients showed V-incommitance and twitch abduction on vertical saccades. Electromyography showed lateral rectus muscle firing activity during upgaze and downgaze.
Our patients showed synergistic innervation between the lateral rectus muscle and ipsilateral vertical acting muscles documented by electromyography.
我们报告三例患有罕见型杜安眼球后退综合征的患者。
通过眼电图记录眼球运动。一名患者接受了肌电图检查。
所有患者在垂直扫视时均表现出V型内转受限和抽动性外展。肌电图显示在向上注视和向下注视期间外直肌有放电活动。
我们的患者经肌电图证实外直肌与同侧垂直作用肌之间存在协同神经支配。
