Your corneas are the clear layers that sit on top of the pupil and the iris. Corneas act as protectors for the iris and the lens, they also have a part to play in focusing light.

Corneas are hard and relatively tough, but they are sensitive to touch and can be damaged by a range of conditions and diseases. Here, we go over the symptoms of corneal diseases and some of the causes. We’ll also take a look at some of the most common corneal diseases.

The most common corneal diseases

There are several different types of corneal disease. The most commonly seen are:


An inflammation that affects the cornea. The inflammation occurs as a result of an infection, a fungus, or some bacteria entering the cornea.

Ocular herpes

This is herpes of the eye and it is most often caused by the herpes simplex virus, the same virus that causes cold sores. This condition is identified by sores appearing on the cornea. There is no cure for the herpes virus, but the condition can be controlled with anti-viral medication.

Shingles (herpes zoster)

Shingles is a condition whereby the Chicken Pox virus reappears in people who have already had Chicken Pox, this mostly happens in later life. Like ocular herpes, shingles can cause sores on the cornea and the condition is controlled with anti-viral treatments.

Corneal dystrophies
