Congenital Oculomotor Nerve Paresis With Isolated Cyclic Pupillary Spasms

open access: yes, 2015
Cyclic oculomotor nerve paresis is a rare and mostly congenital disorder. It is characterized by unilateral oculomotor nerve paresis with periodic spasms causing eyelid elevation, miosis and contraction of one or more of the extraocular muscles ...

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

open access: yesFrontiers 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.

Contralateral migration of oculomotor neurons is regulated by Slit/Robo signaling [PDF]

open access: yes, 2016
Oculomotor neurons develop initially like typical motor neurons, projecting axons out of the ventral midbrain to their ipsilateral targets, the extraocular muscles.

The vestibuloocular reflex of the adult flatfish. I. Oculomotor organization

open access: yes, 1985
The flatfish species constitute a natural paradigm for investigating adaptive changes in the vertebrate central nervous system. During metamorphosis all species of flatfish experience a 90 degree change in orientation between their vestibular and ...

Heterozygous mutations of the kinesin KIF21A in congenital fibrosis of the extraocular muscles type 1 (CFEOM1)

open access: yes, 2003
Congenital fibrosis of the extraocular muscles type 1 (CFEOM1; OMIM #135700) is an autosomal dominant strabismus disorder associated with defects of the oculomotor nerve.

Examination of the Annular Tendon (Annulus of Zinn) as a Common Origin of the Extraocular Rectus Muscles: 2. Embryological Basis of Extraocular Muscles Anomalies

open access: yes, 2020
Purpose: Many reports have described anomalous connections of the superior rectus (SR) with other extraocular rectus muscles, in which additional heads of the other three rectus muscles likely provided the connections.

Chronic oculomotor nerve palsy secondary to a sphenoid–cavernous sinus lesion in an adolescent: a case report and literature review

open access: yesBMC Ophthalmology
Background Oculomotor nerve (cranial nerve III) palsy in children and adolescents is uncommon and typically suggests an underlying structural lesion rather than microvascular ischemia.

A Case of Progressive Stroke on Posterior Circulation with Transient Bilateral Oculomotor Palsy

open access: yesCase Reports in Neurological Medicine, 2018
Infarction located in the midbrain and pons presents various ophthalmic symptoms, because of the damage of the nuclei that control the movement of internal and external ocular and palpebral muscles.

Isolated oculomotor nerve palsy related to sinusitis? [PDF]

open access: yes, 2018
The association of sinusitis with ocular motility disorders is a seductive theory due to their close anatomical vicinity. Typically, sinusitis can influence ocular motility by affecting single muscles or a combination of muscles and/or cranial nerves due
