Many conditions can cause exophthalmos.
In some types of thyroid disease, especially Graves' disease, the tissues in the eye socket swell, and deposits of unusual material push the eyeball forward. Exophthalmos can occur suddenly from bleeding behind the eye or from inflammation in the eye socket. Tumors, either cancerous or noncancerous, can form in the eye socket behind the eyeball and push it forward. Cavernous sinus thrombosis causes swelling from the backup of blood in the veins exiting the eye. The treatment depends on the cause.
