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

Response of oculomotor neurons to eye muscle stretch

Canadian Journal of Physiology and Pharmacology, 1977
Neurons within the ventral portion of the oculomotor nucleus respond to stretch of extraocular muscles. Response latencies range from 30 to 170 ms. Antidromically identified extraocular motoneurons with this input have slowly conducting axons in the range of 30 to 50 m/s.

Dynamics of nystagmus after chemodenervation of oculomotor muscles

Russian ophthalmology of children, 2022
Purpose.. To increase the effectiveness of treatment of patients with permanent nystagmus with injections of botulinum toxin type A (BTA). Material and methods. Treatment was carried out in 25 patients (50 eyes) with permanent oscillatory movements nystagmus of various amplitude using injections of BTA into oculomotor muscles.

Oculomotor nerve and muscle abnormalities in congenital fibrosis of the extraocular muscles

Annals of Neurology, 1997
AbstractCongenital fibrosis of the extraocular muscles is an autosomal dominant congenital disorder characterized by bilateral ptosis, restrictive external ophthalmoplegia with the eyes partially or completely fixed in an infraducted (downward) and strabismic position, and markedly limited and aberrant residual eye movements.

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 decapod cephalopods: eye muscles, eye muscle nerves, and the oculomotor neurons in the central nervous system

Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 1993
Fourteen extraocular eye muscles are described in the decapods Loligo and Sepioteuthis , and thirteen in Sepia ; they are supplied by four eye muscle nerves. The main action of most of the muscles is a linear movement of the eyeball, only three muscles produce strong ...

Oculomotor system: A dual innervation of the eye muscles from the abducens, trochlear, and oculomotor nuclei

Movement Disorders, 2002
The twitch fibers, orSIFs, are the type of muscle fibers that constitute allskeletal muscles, i.e., they respond to electrical excita-tion with an all-or-nothing response that propagatesalong the whole length of the fiber. They are innervatedby large en plaque motor endplates in an endplate zoneoccupying the central third of the muscle.

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 ...

Sensitivity analysis of human oculomotor muscle model.

Biomedical sciences instrumentation, 1990
Sensitivity analysis is a procedure for examining the importance of model parameters with respect to the input or output of the model. Presented is a sensitivity analysis of a recently updated fourth order linear homeomorphic oculomotor model. Each muscle is modeled as a viscoelastic parallel combination connected to an active state tension generator ...
