Purpose: To disclose the association between spinocerebellar ataxia with oculomotor apraxia and high grade (7 diopters) congenital astigmatism. Methods: Single observational case report. A 39-year-old patient affected by spinocerebellar ataxia from the age of 20 was submitted to genetic and ophthalmic investigations to reach a diagnosis. Results: Genetic testing did not lead to a sure diagnosis...

RATIONALE Diabetic oculomotor nerve palsies, also called ischemic third nerve palsies, are the most common etiologic subset of oculomotor nerve palsy in adults. Diabetic oculomotor nerve palsies typically present with ptosis and diplopia, but pupillary function is often spared. The oculomotor nerve separates into superior division and inferior division, with the superior division innervating th...

Binocular eye movements form a finely tuned system that requires accurate coordination of the oculomotor dynamics of the brainstem control nuclei when tracking the fine binocular disparities required for 3D vision. They are particularly susceptible to disruption by brain injury and other neural dysfunctions. Here, we report functional magnetic resonance imaging activation of the brainstem oculo...

Oculomotor Nerve Pathway The oculomotor nerve arises from the complex oculomotor nuclei situated ventrolaterally in the periaqueductal gray matter of the midbrain at the level of the superior colliculus. The nuclei consist of groups of large and small multipolar cells which are arranged longitudinally on each side of the midline supplying one of the four extraocular muscles. A single median nuc...

One 57-year-old lady with uncontrolled hypertension and right-side pupil-sparing oculomotor palsy visited our emergency department. Computed tomographic angiography revealed right-side persistent primitive trigeminal artery. Her symptoms dramatically improved after her blood pressure went under control. To our knowledge, this is the first case report that describes the relation between blood pr...

Oculomotor function critically depends on how signals representing saccade direction and eye position are combined across neurons in the lateral intraparietal (LIP) area of the posterior parietal cortex. Here we show that populations of parietal neurons exhibit correlated variability, and that using these interneuronal correlations yields oculomotor predictions that are more accurate and also l...

Optometry & Vision Development ABSTRACT Individuals with traumatic brain injury present with a constellation of oculomotor dysfunctions and correlated symptoms. Simple and effective clinical oculomotor-based training procedures will be presented with respect to the versional, vergence, and accommodative systems, and their interactions. These therapeutic procedures can also be applied as needed ...

Joubert syndrome (JS) is a rare autosomal dominant gene disorder that heterogeneously inherited and manifests itself as hypotonia, ataxia, breathing abnormalities, developmental delay, intellectual disabilities, oculomotor apraxia, brain malformation [1-3].
