The sclera is the white outer wall of the eye. Scleritis is present when this area becomes swollen or inflamed.
Inflammation - sclera
Scleritis is often linked to autoimmune diseases. These diseases occur when the body's immune system attacks and destroys healthy body tissue by mistake. Rheumatoid arthritis and systemic lupus erythematosus are examples of autoimmune diseases. Sometimes the cause is unknown.
Scleritis occurs most often in people between the ages of 30 and 60. It is rare in children.
Symptoms of scleritis include:
- Blurred vision
- Eye pain and tenderness -- severe
- Red patches on the normally white part of the eye
- Sensitivity to light -- very painful
- Tearing of the eye
A rare form of this disease causes no eye pain or redness.
Exams and Tests
Your health care provider will perform the following tests:
- Eye exam
- Physical exam and blood tests to look for conditions that may be causing the problem
It is important for your provider to determine if your symptoms are due to scleritis. The same symptoms can also be a less severe form of inflammation, such as episcleritis.
Treatments for scleritis may include:
- Corticosteroid eye drops to help reduce the inflammation
- Corticosteroid pills
- Newer, nonsteroid anti-inflammatory drugs (NSAIDs) in some cases
- Certain anticancer drugs (immune-suppressants) for severe cases
If scleritis is caused by an underlying disease, treatment of that disease may be needed.
In most cases, the condition goes away with treatment. But it may come back.
The disorder causing scleritis may be serious. However, it may not be discovered the first time you have the problem. The outcome will depend on the specific disorder.
Complications may include:
- Return of scleritis
- Side effects of long-term corticosteroid therapy
- Perforation of the eyeball, leading to vision loss if the condition is left untreated
When to Contact a Medical Professional
Call your provider or ophthalmologist if you have symptoms of scleritis.
Most cases cannot be prevented.
People with autoimmune diseases, may need to have regular check-ups with an ophthalmologist familiar with the condition.
