Changes in Extraocular Muscle Volume During Ocular Duction
PURPOSE It has been tacitly assumed that overall extraocular muscle (EOM) volume is conserved during contraction and relaxation, yet this assumption has been untested up to now. We used high-resolution magnetic resonance imaging (MRI) to determine if total EOM volume changes during relaxation and contraction. METHODS Surface coil MRI in quasi-coronal planes was obtained in target-controlled, ...

متن کاملDeterminants of Extraocular Muscle Volume in Patients with Graves' Disease
Background. To examine factors contributing to extraocular muscle (EOM) volume enlargement in patients with Graves' hyperthyroidism. Methods. EOM volumes were measured with orbital magnetic resonance imaging (MRI) in 39 patients with recently diagnosed Graves' disease, and compared to EOM volumes of 13 normal volunteers. Thyroid function tests, uptake on thyroid scintigraphy, anti-TSH-receptor ...
متن کاملGraves' ophthalmopathy: I. Simple CT estimates of extraocular muscle volume.
Graves' ophthalmopathy is an autoimmune inflammatory process affecting primarily the extraocular muscles. The enlargement of these muscles is responsible for most of the important manifestations of the disease, including proptosis, lid retraction, diplopia, and optic neuropathy. Recently the optic neuropathy has been shown to correlate with extraocular muscle volume as determined by computed to...
متن کامل[Ocular changes during pregnancy].
Pregnancy can cause several alterations in human eye function in healthy condition as well in ocular disease; these effects on the eyes are divided into three categories: physiologic alterations, ocular diseases changes already existing before the pregnancy, and pathological alterations. The present text proposes a bibliographical revision on the theme. The authors researched PubMed (MEDLINE) a...
