Issue Description

Other Names
Exophthalmos


Causes
Complete or partial dislocation from the orbit is possible from trauma or swelling of surrounding tissue resulting from trauma.

Symptoms
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.

Diagnosis

Treatment
If left untreated, exophthalmos can cause the eye lids to fail to close during sleep leading to corneal dryness and damage. The process that is causing the displacement of the eye may also compress the optic nerve or ophthalmic artery leading to blindness.
