There are a number of eye-related conditions that may affect a person with Crohn’s disease.

Episcleritis is a common eye-related disorder for those with Crohn’s disease. Episcleritis is the inflammation of the episclera, which is the tissue between the outermost layer of the eye and the white part, or sclera, underneath.

Symptoms include:

  • tenderness to touch
  • watery eyes
  • redness
  • bright red spots on the sclera
  • mild pain

Unlike some other eye-related conditions that people with Crohn’s disease may experience, episcleritis does not cause sensitivity to light or blurred vision. It is also less painful than other eye-related conditions.

Scleritis

Scleritis is the inflammation of the sclera.

Symptoms include:

  • redness of the eye
  • watery eyes
  • pain in or around the eye
  • burning
  • blurry vision
  • headaches
  • difficulty sleeping
  • sensitivity to light

In extreme cases, inflammation can lead to the thinning of the sclera, which also gives the eye its shape.

Uveitis

Uveitis is the inflammation of the uvea — a layer of tissue that includes the iris — just beneath the sclera. Uveitis affects people with Crohn’s disease less frequently than scleritis.

This condition is more serious than episcleritis as it can lead to glaucoma or even vision loss if a person does not receive treatment.

Symptoms include:

  • sensitivity to light
  • blurred vision
  • pain
  • redness

These symptoms may occur suddenly or develop slowly over time.

Keratopathy

Keratopathy is a disorder that affects the cornea, the clear outer part of the eye. It often results in blister-like swelling.

Other symptoms include:

  • sensitivity to light
  • excess of tears or discharge
  • irritation
  • the feeling that an object has become stuck in the eye

Dry eye

Dry eye, also known as keratoconjunctivitis sicca, occurs when there is a lack of tear production. It can often feel as though sand or another foreign body is in the eye.

Other symptoms include:

  • pain
  • burning
  • redness
  • itching
  • stinging

Dry eye has many different potential causes, however. If someone with Crohn’s experiences dry eye, there could be a different underlying cause behind it.
