exophthalmos

n. protrusion of the eye from its socket (Medicine)

Exophthalmos is a bulging of the eye anteriorly out of the orbit. Exophthalmos can be either bilateral (as is often seen in 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.
