2023年6月26日 · Internuclear ophthalmoplegia is an ocular movement disorder caused by a lesion of the medial longitudinal fasciculus. It is characterized by impaired adduction of the ipsilateral eye with nystagmus of the abducting eye.

Internuclear ophthalmoplegia is the medical term for one (or both) of your eyes not moving when you look to the side. It’s most commonly caused by strokes and multiple sclerosis (MS).

Internuclear ophthalmoplegia or ophthalmoparesis (INO) is an ocular movement disorder that presents as an inability to perform conjugate lateral gaze and ophthalmoplegia due to damage to the interneuron between 2 nuclei of cranial nerves (CN) VI and CN III (internuclear).

Internuclear ophthalmoplegia (INO) is a disorder of conjugate lateral gaze in which the affected eye shows impairment of adduction. When an attempt is made to gaze contralaterally (relative to the affected eye), the affected eye adducts minimally, if at all. The contralateral eye abducts, however with nystagmus.

A lesion blocking the path between the ipsilateral sixth nerve nucleus and the contralateral third nerve nucleus results in an internuclear ophthalmoplegia. Find an Ophthalmologist Search

2024年11月10日 · Internuclear ophthalmoplegia (INO) describes a clinical syndrome of impaired adduction in one eye with dissociated horizontal nystagmus of the other abducting eye, due to a lesion in the medial longitudinal fasciculus (MLF) ipsilateral to the eye unable to adduct.

Internuclear ophthalmoplegia results from a lesion in the medial longitudinal fasciculus, which coordinates abduction of one eye with adduction of the other. Common causes are multiple sclerosis in young people (often bilateral) and stroke in older people (typically unilateral).

2024年11月11日 · WEMINO is a clinical ocular motor syndrome characterized by unilateral slow, hypometric adducting saccades with exotropia and hypertropia of the ipsilateral eye. We propose that it results from discrete unilateral damage to burst-tonic fibers in the medial longitudinal fasciculus (MLF) with sparing of the adjacent extrafascicular pathways.

2020年1月22日 · What are 4 findings of a unilateral internuclear ophthalmoplegia? 1. Deficit of adduction (slowing of adducting saccades) ipsilateral to the lesion. 2. Nystagmus of the contralateral abducting eye.

Internuclear ophthalmoplegia involves paresis of ipsilateral eye adduction in horizontal gaze without convergence being affected. The condition can be unilateral or bilateral. In horizontal gaze, the medial longitudinal fasiculus on each side of the brainstem allows abduction of one eye to be coordinated with the other eye’s adduction.
