Muscle coenzyme Q10 deficiencies in ataxia with oculomotor apraxia 1

Neurology, 2007
APTX gene mutations responsible for ataxia-oculomotor apraxia 1 (AOA1) were identified in a family previously reported with ataxia and coenzyme Q10 (CoQ10) deficiency. We measured muscle CoQ10 levels in six patients with AOA1 and found decreased levels in five. Patients homozygous for the W279X mutation had lower values (p = 0.003). A therapeutic trial

ASSOCIATED MOVEMENTS IN THE OCULOMOTOR AND FACIAL MUSCLES

Archives of Neurology And Psychiatry, 1946
ABNORMAL motor phenomena belonging—generally speaking—to the vast group of hyperkineses do occur in the oculomotor muscles after incomplete recovery from a third nerve palsy. They constitute, as Bielschowsky 1 rightly said, "a problem of great biologic interest." But this difficult and fascinating problem has been much neglected in the neurologic ...

Oculomotor function in the rhesus monkey after deafferentation of the extraocular muscles

Experimental Brain Research, 2001
The function of extraocular muscle proprioception in the control of eye movements remains uncertain. In this study, we examined the effect of bilateral proprioceptive deafferentation of the extraocular muscles on eye movements in two rhesus monkeys.

Medial rectus muscle anchoring in complete oculomotor nerve palsy

Journal of American Association for Pediatric Ophthalmology and Strabismus, 2015
The management of exotropia resulting from complete oculomotor nerve palsy is challenging. Conventional therapeutic interventions, including supramaximal resection and recession, superior oblique tendon resection and transposition, and several ocular anchoring procedures have yielded less-than-adequate results.

The oculomotor system of Daphnia magna

Cell and Tissue Research, 1987
The highly mobile cyclopic compound eye of Daphnia magna is rotated by six muscles arranged as three bilateral pairs. The three muscles on each side of the head share a common origin on the carapace and insert dorsally, laterally and ventrally on the eye.

Identification of human oculomotor system for quantitative diagnostics of eye muscle diseases

Computers in Biology and Medicine, 1983
Various discrete parameter estimation methods are explained and applied to the eye muscle model of Collins. Their effectiveness and accuracy are studied. Comparing saccadic eye movements to the motions of a fixation target data for parameter estimation are provided. As a first application, saccades of a subject with a Duane-Syndrome are evaluated.

A new X‐linked syndrome with muscle atrophy, congenital contractures, and oculomotor apraxia [PDF]

American Journal of Medical Genetics, 1985
AbstractSix men from three generations of one family had manifestations of a possible new syndrome. All had congenital contractures of the feet at birth, a slowly progressive predominantly distal muscle atrophy, dyspraxia of the eye, face, and tongue muscles, and mild mental retardation.

Retractor bulbi muscle responses to oculomotor nerve and nucleus stimulation in the cat

Brain Research, 1981
This study demonstrates the presence of retractor bulbi motoneurons within the oculomotor nucleus which activate muscle units within all 4 slips of the cat retractor bulbi muscle. These muscle units are mechanically different and physiologically separate from retractor bulbi muscle units innervated by the abducens nerve.

The statocyst-oculomotor system ofoctopus vulgaris: extraocular eye muscles, eye muscle nerves, statocyst nerves and the oculomotor centre in the central nervous system

Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1984
Seven extraocular eye muscles are described inOctopus vulgaris.There are three powerful recti muscles that produce linear movements and four oblique muscles producing rotation. Some of these oblique muscles are very thin sheets passing halfway round the eyeball.

The Tonic Oculomotor Function of the Cervical Joint and Muscle Receptors

2015
Cases of peripheral labyrinthine lesions were examined by stimulation of the cervical joint and muscle receptors. Head-chin (HC) position to one side induced compensatory oculomotor tone (ipsilateral nystagmus), which depended on the function of the horizontal canal of that side.
