We report the case of a patient with isolated central oculomotor impairment and anti-GQ1b antibody. The patient was referred to us with acute vertical diplopia. The neurological examination revealed right internuclear ophthalmoplegia (INO), skew deviation and mild gait ataxia. Extensive laboratory analyses, CSF study, multimodal evoked potentials and brain MRI were normal. Eye movement recordin...

It is not sure if persons with dyslexia have ocular motor deficits in addition to their deficits in rapid visual information processing. A 15-year-old boy afflicted by severe dyslexia was submitted to saccadic eye movement recording. Neurological and ophthalmic examinations were normal apart from the presence of an esophoria for near and slightly longer latencies of pattern visual evoked potent...

A 62-year-old woman with relapsing-remitting multiple sclerosis suddenly complained of diplopia associated with bilateral adduction impairment, nystagmus of the abducting eye bilaterally, and sparing of abduction, convergence, and vertical eye movements, consistent with bilateral internuclear ophthalmoplegia. Within 1 week, she had developed a complete horizontal gaze paralysis even with the oc...

Wall-eyed bilateral internuclear ophthalmoplegia (WEBINO) is a rare disorder consisting of a bilateral adduction deficit and primary gaze position exotropia. Associated with bilateral medial longitudinal fasciculus lesions, it has been mostly reported in patients with multiple sclerosis and brainstem stroke. A 72-year-old man with characteristic clinical features of progressive supranuclear pal...

Multiple sclerosis is a disease of the central nervous system whose clinical manifestations include animportant group of ocular pathologies, e.g., unilateral retrobulbar neuritis, uveitis, decreased visual function, nystagmus, internuclear ophthalmoplegia, diplopia, optic papillitis and Marcus Gunn pupil. Additionally, it is not generally appreciated that bitemporal hemianopia, usually associat...

One-and-a-half syndrome is characterized by combination of the clinical features of unilateral horizontal gaze palsy and internuclear ophthalmoplegia. The common symptoms are double vision and oscillopsia. The lesion is located in the paramedian pontine reticular formation, involving the centre of horizontal gaze and medial longitudinal fasciculus. More extensive brainstem damage may result in ...

This case talks about 'One-and-a-half plus syndrome', a clinical syndrome affecting binocular vision and facial nerve. One-and-a-half plus syndrome is a less known clinical syndrome which constitutes of a conjugate horizontal gaze palsy in one direction and an internuclear ophthalmoplegia in the other direction. Despite the known association between ischemia, autoimmune disorders, multiple scle...

Clinical comparisons were made between Japanese patients with multiple sclerosis (66 cases) and neuro-Behçet's syndrome (23 cases). Those with neuro-Behçet showed marked male predominance, while those with multiple sclerosis showed slight female preponderance. Both showed encephalomyelopathy disseminated in time and space. Patients with multiple sclerosis, however, showed a more polyphasic cour...
