Vernal conjunctivitis is long-term (chronic) swelling (inflammation) of the outer lining of the eyes due to an allergic reaction.
Causes, incidence, and risk factors
Vernal conjunctivitis often occurs in people with a strong family history of allergies, such as allergic rhinitis, asthma, and eczema. It is most common in young males, and most often occurs during the spring and summer.
The area around the cornea where the white of the eye and the cornea meet (limbus) may become rough and swollen
The inside of the eyelids (usually the upper ones) may become rough and covered with bumps and a white mucus
Signs and tests
The health care provider will perform an eye exam.
Avoid rubbing the eyes, because this can irritate them more.
Cold compresses (a clean cloth soaked in cold water and then placed over the closed eyes) may be soothing.
Lubricating drops may also help soothe the eye.
If home-care measures do not help, you may need to be treated by your health care provider. This may include:
Antihistamine or anti-inflammatory drops that are placed into the eye
Eye drops that prevent a type of white blood cell called mast cells from releasing histamine (may help prevent future attacks)
Mild steroids that are applied directly to the surface of the eye (for severe reactions)
The condition continues over time (is chronic). It gets worse during certain seasons of the year, usually spring and summer. Treatment may provide relief.

Calling your health care provider
Call your health care provider if your symptoms continue or get worse.
Using air conditioning or moving to a cooler climate may help prevent the problem from getting worse in the future.
