|
| '''Exophthalmos''' is a bulging of the [[eye]] anteriorly out of the [[orbit (anatomy)|orbit]]. Exophthalmos can be either bilateral (as is often seen in [[Graves-Basedow disease|Grave's Disease]]) or unilateral (as is often seen in an orbital tumor). Measurement of the degree of exophthalmos is performed using an exophthalmometer. Complete or partial dislocation from the orbit is also possible from trauma or swelling of surrounding tissue resulting from trauma.
| | ==[[Exophthalmos historical perspective|Historical Perspective]]== |
|
| |
|
| In the case of Graves Disease, the displacement of the eye is due to abnormal connective tissue deposition in the orbit and extraocular muscles which can be visualized by [[Computed axial tomography|CT]] or [[MRI]].<ref>{{cite book | author = Owen Epstein, David Perkin, John Cookson, David P de Bono | title = Clinical examination | edition=3rd edition | publisher = Mosby | location = St. Louis | year = 2003 | month=April | id = ISBN 0-7234-3229-5 }}</ref>
| | ==[[Exophthalmos pathophysiology|Pathophysiology]]== |
|
| |
|
| If left untreated, exophthalmos can causes the eye lids to fail to close during sleep leading to [[cornea|corneal]] damage. The process that is causing the displacement of the eye may also compress the [[optic nerve]] or [[ophthalmic artery]] leading to [[blindness]].

|
| *A "bulging" of the eye due to foreward displacement. Some sources define exophthalmos as a protrusion of the globe greater than 18 mm and proptosis as a protusion equal to or less than 18 mm. (Epstein et al, 2003). Others define "exophthalmos" as protusion secondary to endocrine dysfunction and "proptosis" as any non-endocrine-mediated protusion.
