Topographical anatomy of the annulus of Zinn

Scientific Reports, 2022
The anatomy and even existence of a common tendinous origin of the extraocular eye muscles, or annulus of Zinn, has widely been debated in anatomical literature. This study explored the anatomical origins of the recti muscles, their course into the orbit

Isolated Lateral Rectus Myositis – A Case Series

APIK Journal of Internal Medicine, 2022
Idiopathic orbital myositis is a rare, nongranulomatous, noninfective, nonneoplastic inflammation of the orbit. It can involve either a single extraocular muscle or multiple extraocular muscles, unilaterally or bilaterally.

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 ...

Extraocular Motor System Exhibits a Higher Expression of Neurotrophins When Compared with Other Brainstem Motor Systems

Frontiers in Neuroscience, 2017
Extraocular motoneurons resist degeneration in diseases such as amyotrophic lateral sclerosis. The main objective of the present work was to characterize the presence of neurotrophins in extraocular motoneurons and muscles of the adult rat.

Features of bioelectric potentials of the extraocular horizontal rectus muscles in concomitant esotropia and exotropia

Journal of Ophthalmology, 2015
Introduction. There is no objective method currently available for assessing the extraocular muscles functional status, which could be considered definitely effective and convenient for the extensive use in ophthalmological practice.

Alternating Hypotropia with Pseudoptosis: A New Phenotype of Congenital Cranial Dysinnervation Disorder

Case Reports in Ophthalmology, 2018
Congenital cranial dysinnervation disorders, also known as CCDDs, are characterized by aberrant innervation to extraocular and facial muscles resulting in unusual forms of incomitant strabismus.
