Vernal keratoconjunctivitis

Vernal keratoconjunctivitis (pronunciation: vur-nuhl ker-uh-toh-kon-junk-tuh-vahy-tis) is a chronic, severe allergic eye disease that primarily affects children and young adults. It is characterized by inflammation of the cornea and conjunctiva, the outermost layers of the eye.

Etymology

The term "vernal" is derived from the Latin word "vernalis," meaning "of the spring," as the condition often worsens during the spring season. "Keratoconjunctivitis" is a combination of "kerato," from the Greek "keras" (horn), referring to the cornea, and "conjunctivitis," inflammation of the conjunctiva.

Symptoms

Symptoms of vernal keratoconjunctivitis include redness, itching, and watering of the eyes. In severe cases, it can cause corneal ulcers and scarring, which can lead to vision loss.

Causes

Vernal keratoconjunctivitis is thought to be caused by an allergic reaction, although the exact allergen is often unknown. It is more common in individuals with a history of allergies, asthma, or eczema.

Treatment

Treatment typically involves the use of anti-allergy eye drops and, in severe cases, topical steroids. In some cases, immunotherapy may be recommended.
