Analysis of Motion and Internal Loading in Redundantly Actuated Human Eyeball

IEEE Access, 2020
The 3-DOF rotational motion of the human eyeball is created by using six extraocular muscles. For the force-redundant system of the human eyeball, a load distribution algorithm is proposed to investigate the dynamics and intrinsic load distribution of ...

Successful repair of injury to the eyelid, lacrimal passage, and extraocular muscle

GMS Ophthalmology Cases, 2016
Introduction: Injury is a known cause of monocular blindness. Ocular trauma may affect lacrimal canaliculi and the extraocular muscle. We report this case as it includes injury to lid, lacrimal canaliculi and inferior rectus.

Dual encoding of muscle tension and eye position by abducens motoneurons [PDF]

, 2011
Extraocular muscle tension associated with spontaneous eye movements has a pulse-slide-step profile similar to that of motoneuron firing rate. Existing models only relate motoneuron firing to eye position, velocity and acceleration.

Prognostic factors of restrictive myopathy in thyroid eye disease

Scientific Reports, 2021
To investigate the prognostic factors of extraocular muscle restriction in patients with thyroid eye disease (TED), 65 patients with TED and restrictive myopathy were evaluated. Demographics, clinical activity score (CAS), smoking status, thyroid disease

CGRP Inhibits Apoptosis and Protects against Extraocular Muscle Atrophy in Patients with Concomitant Exotropia through the AKT/CREB Pathway

Journal of Bio-X Research
Concomitant exotropia is a common chronic eye disease characterized by abnormal movement of the extraocular muscles caused by a functional imbalance of the nerves related to the movement of the extraocular muscles. This study revealed that the expression
