BACKGROUND Seeing triple is a rare complaint, so anatomically unlikely that it is often considered a diagnostic symptom of hysteria. OBJECTIVE To evaluate the complaint of triple vision among a large group of neurological inpatients. DESIGN Personal case series during a 34-year period. SETTING Neurology and neurosurgery wards of the University of Southern California-Los Angeles County Med...

A 51-year-old man developed positional vertigo, ataxia, dysgeusia, diplopia, and oscillopsia. Eye movement examination and video-oculographic recording disclosed primary position upbeat nystagmus (PPUN) and a right internuclear ophthalmoplegia. Brain MRI showed a small focal lesion in the right dorsal tegmentum of the caudal pons with signal characteristics consistent with a primary demyelinati...

BACKGROUND Narcolepsy with cataplexy is caused by a selective loss of hypocretin-producing neurons, but narcolepsy can also result from hypothalamic and rostral brainstem lesions. PATIENT We describe a 38-year-old woman with severe daytime sleepiness, internuclear ophthalmoplegia, and bilateral delayed visual evoked potentials. Her multiple sleep latency test results demonstrated short sleep ...

The Heimann-Bielschowsky phenomenon (HBP) refers to coarse vertical oscillation of the eye with impaired vision. The ocular movements are strictly monocular, occurring only in the eye with amblyopia. The vertical oscillation is of equal velocity in both vertical directions, or may sometimes be greater in the downward than upward direction. HBP develops several years after loss of vision. It can...

BACKGROUND Cerebral thromboembolism is a rare, but well-recognized complication of angiographic procedures. Peduncular hallucinosis (PH) is a form of complex visual hallucinations usually associated with lesions in the midbrain and thalamus. CASE PRESENTATION We report the case of a 79-years-old male patient with internuclear ophthalmoplegia and vivid lilliputian visual hallucinations (pedunc...

Ocular motor disorders are a well recognized feature of multiple sclerosis (MS). Clinical abnormalities of eye movements, early in the disease course, are associated with generalized disability, probably because the burden of disease in affected patients falls on the brainstem and cerebellar pathways, which are important for gait and balance. Measurement of eye movements, especially when used t...

Two women presented with bilateral internuclear ophthalmoplegia evolving in a few days to complete bilateral horizontal gaze paralysis. Convergence and vertical eye movements were normal. Cerebral MRI showed a few small white matter lesions in the lateral ventricle regions, and, at the brainstem level, a single, small, bilateral lesion affecting the posterior part of the medial pontine tegmentu...

A 64-year-old woman, diabetic and hypertensive, presented with sudden onset painless diplopia and alteration of consciousness. She was drowsy with neurological examination revealing exotropia of both eyes in primary position with bilateral internuclear ophthalmoplegia on attempted horizontal gaze (Figure 1a). Pupils were normal bilaterally. Convergence, vertical saccades, pursuits and vestibula...

Patients may refuse, be unable to use, or show nonresponse to conventional steroid treatment of multiple sclerosis (MS) exacerbation. Adrenocorticotropic hormone (ACTH), one of several melanocortin peptides with mechanisms of action beyond steroidogenesis, should be reconsidered in the treatment of MS exacerbations. The current case report presents the treatment outcome of a patient with new-on...
