What Causes Bulging Eyes?
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:
- Research the topic
- Find a doctor with the time
- Use a diagnostic computer system.
The process is the same, whichever method is used.
Step 1: List all Possible Causes
We begin by identifying the disease conditions which have "bulging eyes" as a symptom. Here are seven possibilities:
- Mercury Toxicity
- Orbital Cellulitis
- Choroidal Hemangioma
- Brain Tumor
- Histiocytosis X
Step 2: Build a Symptom Checklist
We then identify all possible symptoms and risk factors of each possible cause, and check the ones that apply:
rapid decline in speaking ability
major unexplained weight gain
metallic taste in mouth
slightly impaired ability to walk
severe fatigue after slight exertion
being very easily irritated
... and more than 70 others
Step 3: Rule Out or Confirm each Possible Cause
A differential diagnosis of your symptoms and risk factors finds the likely cause of bulging eyes:

Have you noticed, or have others commented, that your eyes seem to be bulging out or protruding?
→ No / don't know
→ Yes, due to past hyperthyroidism now resolved

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).
