Vernal conjunctivitis is a seasonal inflammation of the outer lining of the eyes, which is thought to be due to an allergic reaction.
Causes, incidence, and risk factors
Vernal conjunctivitis is thought to be caused by allergic reactions. Often, it occurs in people with a strong family history of allergies. It is most common during the spring and summer.
The condition is characterized by itchy, watery eyes. The underside of the eyelids may become rough and covered with bumps and a whitish mucus. Tissue around the cornea where the white of the eye and the cornea meet (limbus) may become rough and swollen. If this swelling and roughness moves over the cornea, it may cause scarring and decreased vision.
