Metastases to extraocular muscles from breast cancer: case report and up-to-date review of the literature

open access: yesBMC Cancer, 2019
Unilateral or bilateral metastases to extraocular muscles are very rare in breast cancer. We describe a case of inferior rectus extraocular muscle involved by ductal luminal B/Her-2 neu negative breast cancer, observed in a cohort of 580 patients.

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

open access: yesJournal 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.

A rare variation of superior rectus muscle [PDF]

open access: yesFolia Medica, 2023
The extraocular muscles are responsible for all eye movements required to track and fix objects. Superior rectus muscle is located in the superior level of the orbital cavity, below musculus levator palpebrae superioris, tilted slightly to the lateral ...

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

open access: yesCase 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.

Altered Protein Composition and Gene Expression in Strabismic Human Extraocular Muscles and Tendons

open access: yesInvestigative Ophthalmology and Visual Science, 2016
Purpose To determine whether structural protein composition and expression of key regulatory genes are altered in strabismic human extraocular muscles. Methods Samples from strabismic horizontal extraocular muscles were obtained during strabismus surgery

Anomalous extraocular muscles in Crouzon syndrome with V-pattern exotropia

open access: yesIndian Journal of Ophthalmology, 2020
Strabismus associated with Crouzon syndrome is common and often complex. V-pattern strabismus is most commonly reported in this condition and is mainly thought to be due to an excyclorotation of the orbits and rectus muscle pulleys.

Extraocular movements

open access: yesKerala Journal of Ophthalmology, 2020
Extraocular muscles facilitate the eye movements. Examination of extraocular movements helps in the diagnosis of different local and systemic conditions. It also helps in differentiating congenital and acquired lesions.

Functional characterization of orbicularis oculi and extraocular muscles

open access: yesThe Journal of General Physiology, 2016
Facial muscles are skeletal muscles that control facial expression. Sekulic-Jablanovic et al. characterize orbicularis oculi and extraocular muscles and find divergence in the expression of key molecules for muscle function between facial, extraocular ...
