The device is wearable, and utilizes servo controlled prisms to treat disorders of ocular mobility in non-invasive and non-pharmacologic manner. Probe (20) comprises an eye movement sensor. The device (10) oscillates the image of the world as perceived by a patient in lock step with pathological nystagmus to negate its deleterious effects. Furthermore, the subject treatment device negates only abnormal eye movement. Voluntary, and normal reflex eye movements required for normal vision do not affect operation of the device. In addition to acquired pendular nystagmus (APN), the device is potentially usable to treat non-sinusoidal ocular oscillations (e.g., jerk nystagmus), strabismus, vestibular insufficiency, and other ocular mobility disorders. A corresponding method for treating APN and other eye movement disorders is also described.Field of SearchOf abnormal muscular functioningEye exercising or training type Having means to detect proper distance or alignment (i.e., eye to instrument) Including eye movement detection Using photodetector Including projected target image Including lens selectively insertable in optical path Methods of use Prismatic type Combined Ophthalmic lenses or blanks IMAGE STABILIZATION By movable refractive structure | |
