Eye problems and IBD: Episcleritis in Crohn's disease and ulcerative colitis

What is episcleritis?

Episcleritis is inflammation of the outer superficial coating of the white of the eye called the episclera. In episcleritis the tiny blood vessels of the episclera become inflamed and dilate causing the area to become red. It is the most common eye manifestation in IBD1.

It can be confused with the more serious scleritis which can cause vision changes. Careful examination of the layers of the eye is needed to distinguish between episcleritis and scleritis.

What are the symptoms of episcleritis?

The symptoms of episcleritis include:

  • Red, inflamed-looking whites of the eye - either just one area or the whole white
  • Mild pain, tenderness, burning or itching
  • Watery eyes
It doesn’t affect vision and usually affects one eye, although in some cases can affect both. It is often confused with conjunctivitis (pink eye).

What treatments are there for episcleritis?

Episcleritis often reflects the inflammation in a person’s IBD. If they are experiencing a flare of their disease then they may also experience episcleritis and as their disease is brought under control so might the episcleritis.

In many cases the drug therapy used to bring IBD under control is enough to treat episcleritis. In particular Infliximab has been shown to be effecting in treating episcleritis associated with IBD2. 

Treatment of mild cases may include using artificial tears and cool compresses. In more severe cases, or cases where it doesn't resolve in the treatment of IBD, topical NSAIDs (Non-steroidal anti-inflammatory drugs) may be used or topical steroids such as prednisolone may also be considered.
