Orbital pseudotumor is the swelling of tissue behind the eye in an area called the orbit. The orbit is the hollow space in the skull where the eye sits. The orbit protects the eyeball and the muscles and tissue that surround it. Orbital pseudotumor does not spread to other tissues or places in the body.
Causes of Orbital pseudotumor
The cause is unknown. It mostly affects young women, although it can occur at any age.
Orbital pseudotumor Symptoms
Symptoms may include:
- Pain in eye, and it may be severe
- Restricted eye movement
- Decreased vision
- Double vision
- Eye swelling (proptosis)
- Red eye (rare)
The health care provider will examine your eye to look for signs of pseudotumor. You will also need to have tests to determine if you have:
- A cancerous tumor
- Other eye problems
Tests may include:
Treatment of Orbital pseudotumor
Mild cases may go away without treatment. More severe cases most often respond well to corticosteroid treatment. If the condition is very bad, the swelling may put pressure on the eyeball and damage it. Surgery may be needed to move the bones of the orbit to relieve the pressure.
Most cases are mild and outcomes are good. Severe cases may not respond well to treatment and there may be some loss of vision. Orbital pseudotumor most often involves only one eye.
Severe cases of orbital pseudotumor may push the eye forward so much that the lids cannot cover and protect the cornea. This causes the eye to dry out. The cornea may become cloudy or develop a sore. Also, the eye muscles may not be able to properly aim the eye which can cause double vision.
When to Contact a Health Professional
People with this condition need regular follow up care with an eye doctor who is familiar with the treatment of orbital disease.
Call your health care provider right away if you have any of the following problems:
- Irritation of the cornea
- Decreased vision
