What is it?

Exophthalmos, or proptosis, is a term used to describe the bulging of the eye. It is most commonly caused by thyroid disease. Other causes may include injury to the eyes, bleeding behind the eyes, an infection of the eye socket’s tissue and some tumors. Sometimes, it may cause compression over the optic nerve, causing vision problems, such as double vision. Diagnosis is based upon findings from medical history and eye examination. Further evaluation may include imaging tests and blood tests. Treatment may include treating the underlying cause, steroid injections and corrective surgery.
