Inflammatory diseases that affect your vision

23 June 2025

Eye inflammation doesn’t just cause discomfort—it can also be a sign of a more serious condition that, if left untreated, may compromise your vision. Inflammatory eye diseases can appear suddenly or develop gradually, affecting different parts of the eye, from the surface to deeper layers.

Here are the most common types:

1. Uveitis

This is the inflammation of the uvea, which includes the iris, ciliary body, and choroid. It can affect one or both eyes and often causes:

• Eye pain

• Redness

• Light sensitivity

• Blurred vision

Important note: Uveitis may be linked to autoimmune diseases such as rheumatoid arthritis, lupus, or ankylosing spondylitis.

2. Scleritis

Inflammation of the sclera (the white part of the eye). It usually causes deep, intense pain and can be associated with systemic diseases like rheumatoid arthritis.

If left untreated, it can lead to complications such as thinning of the sclera or vision loss.

3. Allergic or Autoimmune Conjunctivitis

While conjunctivitis is usually mild, in some cases—such as in people with autoimmune conditions or chronic allergies—it can cause persistent inflammation and damage to the ocular surface. Symptoms include:

• Itching

• Tearing

• Gritty sensation

• Redness

4. Keratitis

Inflammation of the cornea, the transparent outer layer of the eye. It can be caused by infections or autoimmune disorders. Common symptoms include:

• Pain

• Blurred vision

• Redness

• Excessive tearing

In severe cases, it can leave corneal scars and permanently affect vision.

When should you see an eye doctor?

If you experience symptoms like pain, blurred vision, light sensitivity, or persistent redness, don’t ignore them. Early diagnosis is key to preventing irreversible damage.
