Allergic conjunctivitis is a reaction of the conjunctiva to an allergen — pollen, dust mites, animal dander. Its key symptom: itching. It involves both eyes and is often accompanied by rhinitis (runny nose, sneezing).
The signs
Itching in the foreground, red and watery eyes on both sides, swollen eyelids, sometimes a burning feeling. Seasonal forms (spring pollen) contrast with perennial forms (dust mites, animals), present all year round.
Treatment
Allergen avoidance as far as possible, saline rinses, cold compresses and antihistamine or mast-cell-stabilising eye drops. An oral antihistamine helps when rhinitis is associated. Avoid rubbing your eyes: it keeps the inflammation going.
Severe forms
Some forms (childhood vernal keratoconjunctivitis, atopic forms) are more severe and require close ophthalmological follow-up, sometimes together with an allergist (work-up, desensitisation).
Frequently asked questions
Is it contagious?
No: unlike the viral and bacterial forms, allergic conjunctivitis is not contagious.
Can it damage eyesight?
Common forms are benign. Severe forms (vernal, atopic) can involve the cornea and warrant regular follow-up — as does chronic eye rubbing, which should be avoided.
