Disinserted Extraocular Muscles
American Journal of Ophthalmology, 1975In two patients, a muscle that slipped from the globe posteriorly created the clinical pattern of reduced rotation amplitude, reduced saccadic velocity, reduced active force, and increasing exophthalmos with gaze into the field of action of the muscle.

Review of extraocular muscle biopsies and utility of biopsy in extraocular muscle enlargement
British Journal of Ophthalmology, 2018AimsTo review the distribution of pathology in extraocular muscle (EOM) biopsies performed at a tertiary orbital centre, identify clinical and imaging features which are associated with benign or malignant diseases and indicate when biopsy is necessary for EOM enlargement.MethodsRetrospective case series including 93 patients with EOM enlargement who ...

Extraocular Muscle Enlargement in Acromegaly
Journal of Computer Assisted Tomography, 1982AbstractA review of 10 cases of acromegaly studied by computed tomography to evaluate pituitary adenomas has demonstrated diffuse, significant enlargement of the extraocular muscles in eight patients.

Nebulin isoforms of extraocular muscle
Cell and Tissue Research, 2006The extraocular muscles (EOMs), which are responsible for reflexive and voluntary eye movements, have many unique biochemical, physiological, and ultrastructural features that set them apart from other skeletal muscles. For example, rodent EOMs lack M-lines and express EOM-specific myosin heavy chain (MYH13) and alpha-cardiac myosin heavy chain. Recent

Whereas skeletal muscles generally perform specific limited roles, extraocular muscles (EOMs) have to be responsive over a wider dynamic range. As a result, EOMs have fundamentally distinct structural, functional, biochemical, and immunological properties as compared to other skeletal muscles. At birth, the extraocular muscles are at approximately 50 %

The Extraocular Muscles and Their Actions
1972Apart from its importance in the treatment of squint, an adequate knowledge of the movements of the eyes, and their neuromuscular control, is of considerable value in understanding the physiological mechanisms concerned with the maintenance of posture; moreover, it would seem that our perceptions of objects, and particularly of their spatial ...

Anatomy of the Extraocular Muscles
2019The extraocular muscles have a complex anatomical structure that includes an insertion from the tendinous ring of zinn or the orbital walls and insertion on the globe. They are linked intimately with fascia which forms the pulley system that supports their action.

SLIPPED AND LOST EXTRAOCULAR MUSCLES
Ophthalmology Clinics of North America, 2001A slipped or lost muscle should be considered in the differential diagnosis of a patient presenting with a marked limitation of duction and inability to rotate the eye beyond the midline. Loss of a rectus muscle can occur after strabismus surgery, trauma, paranasal sinus surgery, orbital surgery, or retinal detachment surgery.

Cystic Lesions of the Extraocular Muscles
Ophthalmic Plastic & Reconstructive Surgery, 1996Cystic lesions of the extraocular muscles (EOMs) are uncommon. Six patients with a cystic lesion in an extraocular muscle, as observed by computerized tomography (CT) scanning, were retrospectively identified from the practice of one of the authors (G.C.S.), and their clinical course was reviewed.

Osseous choristoma of an extraocular muscle
Journal of American Association for Pediatric Ophthalmology and Strabismus, 2008Osseous choristoma is a benign lesion defined as normal osseous proliferative tissue in an ectopic site. We report what we believe to be the first osseous choristoma to replace extraocular muscle.
