Bulging eyes can have various causes, ranging in severity from 'needs attention' to 'generally fatal'. Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.
Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms. In order to diagnose bulging eyes, we could:
|Orbital Cellulitis||2%||Ruled out|
|Histiocytosis X||0%||Ruled out|
|Brain Tumor||0%||Ruled out|

Meningiomas – benign tumors that originate in the covering (meninges) around the brain – can cause different symptoms, depending on where they grow. They may cause weakness or numbness, seizures, an impaired sense of smell, bulging eyes, and changes in vision. In elderly people, they may cause memory loss and difficulty in thinking, similar to that found with Alzheimer's disease.
Rarely, damage to the pituitary gland causes bulging eyes (exophthalmos).
Forward displacement of the eye is one symptom of Orbital cellulitis.
A rhabdomyosarcoma near the eye(s) may cause bulging.
