| Summary: | Graves ophtalmopathy (GO), thyroid eye disease (TED) and thyroid - associated orbitopathy (TAO) are terms referring to an autoimmune inflammatory process that affects the adipogenesis of orbital fat and periorbital tissue, associated with dysthyroidism. On imaging, such as computed tomography (CT) thyroid -associated orbitopathy (or thyroid -associated ophtalmopathy) is characterised by symmetrical and bilateral proptosis, secondary to extra-ocular muscle (EOM) enlargement and expansion of orbital fat. Imaging studies ca be useful in identifying patients risk to develop dysthyroid optic neuropathy and initiating early treatment of the condition, avoiding permanent visual loss.
The purpose of this study was to reveal the prevalence of thyroid ophtalmopathy imaging considerations in Graves disease patients. A total of 19 patients were evaluated on computed tomography scanning the diameters and density of extra-ocular muscles, muscular index, proptosis, width of the optic nerve, width of superior ophthalmic vein and lacrimal gland position. |
