There is a short list of causes for enlarged extraocular muscles thyroid associated orbitopathy lymphoma orbital pseudotumor sarcoidosis metastases amyloidosis (very rare) 2. Extraocular muscle enlargement (eome) is most commonly associated with thyroid eye disease, but there are other causes. We report our outcomes of investigating and managing non-thyroid-related eome (ntr-eome). Extraocular muscle enlargement can result from a wide variety of disease processes. Although observations of the pattern of muscle involvement, muscle shape and enhancement, superior ophthalmic vein and cavernous sinus enlargement, sinus and bony wall abnormalities, and proptosis can lead to a limited differential diagnosis in some cases, no radiographic finding in itself seems to be. With enlargement of the extraocular muscle at the orbital apex, the optic nerve is at risk of compression. The orbital fat or the stretching of the nerve due to increased orbital volume may also lead to optic nerve damage. The patient experiences a loss of visual acuity, visual field defect, afferent pupillary defect, and loss of color vision. With enlarged extraocular muscles, features to distinguish between competing diagnostic possibilities are based on imaging in the context of history and clinical signs. Infraorbital nerve enlargement in the presence of muscle enlargement strongly favours a diagnosis of immunoglobulin g4-related disease and reactive lymphoid hyperplasia. The movements of the extraocular muscles take place under the influence of a system of extraocular muscle pulleys, soft tissue pulleys in the orbit. The extraocular muscle pulley system is fundamental to the movement of the eye muscles, in particular also to ensure conformity to listings law. Extraocular muscle enlargement can result from a wide variety of disease processes.

Extraocular muscle enlargement (eome) is most commonly associated with thyroid eye disease, but there are other causes. We report our outcomes of investigating and managing non-thyroid-related. Thyroid-associated orbitopathy (or thyroid-associated ophthalmopathy) is the most common cause of proptosis in adults and is most frequently associated with graves disease. On imaging, it is characterized by bilateral and symmetrical enlargement of the extraocular muscle bellies. The typical distribution is inferior rectus medial rectus superior rectus, with sparing of their tendinous. Extraocular muscles are involved in hyper-thyroidism,sarcoidosis,inflammatorypseudo-. The extraocular muscles are the six muscles that control movement of the eye and one muscle that controls eyelid elevation. The actions of the six muscles responsible for eye movement depend on the position of the eye at the time of muscle contraction.
