Our aim was to evaluate a novel means of assessing ocular motility disorders using MRI.
A GE image of the orbit was acquired in a set plane each time the patient fixed on a series of points spread across the field of view. The images were transferred in sequence to a video recorder to create a cineloop of ocular movement. The technique was used in 33 patients with a range of ocular motility disorders including thyroid eye disease, posttraumatic diplopia, and Duane syndrome.
In addition to anatomical detail, functional information could be derived from motion of the globe, motion of the optic nerve, and contractility of individual muscles. This is of particular use to the ophthalmic surgeon in disorders of ocular motility following eye surgery.
A method of recording eye movements using MRI is described that offers useful functional information in the evaluation of disorders of ocular motility.
我们的目的是评估一种使用磁共振成像（MRI）评估眼球运动障碍的新方法。
每次患者注视分布在视野中的一系列点时，在设定平面获取眼眶的GE图像。图像按顺序传输到录像机以创建眼球运动的动态循环。该技术用于33例患有一系列眼球运动障碍的患者，包括甲状腺眼病、创伤后复视和杜安综合征。
除了解剖细节外，还可从眼球运动、视神经运动和个别肌肉的收缩性中获取功能信息。这对眼科外科医生在眼部手术后的眼球运动障碍中特别有用。
描述了一种使用MRI记录眼球运动的方法，该方法在评估眼球运动障碍时提供了有用的功能信息。
