Background: Dyslexia is the most common learning disorder. Visual and oculomotor deficits in dyslexic children have been reported. The purpose of this study was to measure oculomotor parameters and analyze the effect of oculomotor rehabilitation strategies on dyslexia. Methods: Binocular eye movements were recorded by oculomotor subtype of videonystagmography (VNG) testing on 30 children with ...

one of the important causes of strabismus in all ages is extraocular muscles paralysis due to 3rd, 4th and 6th cerebral nerve palsies. exact and on-time treatment can result in improvement of deviation, am-blyopia and abnormal head posture. we studied epidemiological characteristics of extraocular muscles paralysis. this retrospective study performed on 131 subjects (58% male). records of patie...

purpose: to determine the distribution of oculomotor, abducens, and trochlear nerve palsies in diabetic patients with ocular nerve palsy. methods: this study was performed on all diabetic patients who referred to ophthalmology and neurology clinics at yazd medical science university because of ocular palsy from march 2004 to october 2005. signs and symptoms of the disorder were evaluated. resul...

Oculomotor cistern is normal anatomic structure that is like an arachnoid-lined cerebrospinal fluid-filled sleeve, containing oculomotor nerve. We report a case of arachnoid cyst in oculomotor cistern, manifesting as oculomotor nerve palsy. The oblique sagittal MRI, parallel to the oculomotor nerve, showed well-defined and enlarged subarachnoid spaces along the course of oculomotor nerve. Simpl...

background: ataxia with oculomotor apraxia type 1 (aoa1) shows early onset with autosomal recessive inheritance and is caused by a mutation in the aprataxin (aptx) gene encoding for the aptx protein. methods: in this study, a 7-year-old girl born of a first-cousin consanguineous marriage was described with early-onset progressive ataxia and aoa, with increased cholesterol concentration and decr...

Five visual search experiments found oculomotor and attentional capture consistent with predictions of contingent orienting, contrary to claims that oculomotor capture is purely stimulus driven. Separate saccade and attend-only conditions contained a color target appearing either singly, with an onset or color distractor, or both. In singleton mode, onsets produced oculomotor and attentional ca...

Oculomotor palsy with cyclic spasms is an extremely rare condition whose exact pathophysiology remains a mystery. We followed boy from the onset of symptoms at age ten months until 15 years and documented case video oculography. In addition, he was diagnosed hereditary motor sensory neuropathy (Charcot-Marie-Tooth disease type 1). Although pure coincidence cannot be ruled out, it conceivable th...

balint’s syndrome is a rare neurological disorder associated with bilateral parieto-occipital damage which was described by rezsö bálint in 1909.the syndrome is manifested clinically by the presence of a hemispatial negligence. the lesion is usually inside parietooccipital region bilaterally in most cases but may also be compromised angular convolutions, the dorsolateral area of the occipital l...

We studied the distribution of somatic motor neurons innervating the cat superior rectus 3-6 months after oculomotor nerve injury using intramuscular horseradish peroxidase (HRP). In normal cats, 98% or more of the labelled superior rectus motoneurons were in the contralateral oculomotor subnucleus. Two experimental cats who exhibited little or no evidence of recovery showed few labelled cells ...
