Allergic conjunctivitis is the medical term for eye allergy. Many of the signs and symptoms of eye allergy are not specific, because they involve the classical signs of inflammation including heat, pain, redness, swelling, tearing, irritation, stinging, burning, and photophobia (light sensitivity). Symptoms tend to improve with cool, rainy weather and worsen in warm, dry weather. The true hallmark of eye allergy is itching that can be mild or prominent, and it may last from hours to days.
Covering more than half of all cases, seasonal eye allergy is the most common type of eye allergy. Perennial eye allergy persists throughout the year. Dust mites, animal dander and feathers are the most common allergens. Symptoms are similar to those with seasonal eye allergy, and most patients with the perennial condition experience seasonal exacerbations.
A basic understanding of the eye's immune response coupled with an integrated, stepwise diagnostic approach between your allergist and eye care professional will help you receive a proper diagnosis and treatment.
