Vernal Keratoconjunctivitis is a non-contagious, seasonal allergic
disorder usually occuring during the Spring or warm weather. Major symptoms
include inflammation of the conjunctiva of the eyes, sensitivity to light and
intense itching.
Symptoms
Vernal Keratonconjunctivitis symptoms include inflammation of the outer
membrane of the eye. This causes the eyes to become red and may cause
blurred vision. The eyes become sensitive to light and itch intensely.
Usually both eyes are affected and cobblestone-like changes appear in the
upper palpebral conjunctiva. In other cases, a gelatinous nodule may develop
in the tissue adjacent to the cornea (limbus).
Causes
The cause of Vernal Keratonconjunctivitis is a hypersensitivity or allergic
reaction of the eyes to airborne allergens.
Affected Population
Vernal Keratonconjunctivitis affects males and females in equal numbers. It
is a common disorder occuring most often during the spring or summer.
Related Disorders

Keratoconjunctivitis. Comparisons may be useful for a differential
diagnosis.
Conjunctivitis or "Pink Eye" is caused by an infection of the outer
lining of the eye and eyelids from bacteria or viruses. The eyes become red
and irritated with a sandy or burning feeling. The disease may follow a cold
or sore throat, and is most common in children. Sticky pus is visible in the
eye and can cause the eyelids to stick together. Pink Eye is highly
contagious.

Treatment of Vernal Keratoconjunctivitis is symptomatic and supportive.
