What is allergic conjunctivitis?
When allergens contact the surface of the eye, the thin membrane covering it (the conjunctiva) becomes inflamed, causing itching, redness, watering and puffiness. It is extremely common alongside allergic rhinitis, since the eyes and nose share the same triggers and drainage pathways.
Common symptoms
- Itchy eyes — usually the most prominent symptom, distinguishing it from infective conjunctivitis
- Watering and redness of both eyes
- Puffy eyelids, especially on waking
- Rubbing of the eyes, which can worsen symptoms and irritate the surface further
Common triggers
Seasonal cases are usually driven by pollen; year-round cases are more often linked to house dust mite, pet dander or mold.
Diagnosis
The itch, symmetry (both eyes) and pattern usually point to allergy over infection. Where the trigger isn't obvious, skin prick testing — done for the related nasal symptoms — usually clarifies the eye triggers as well, since they are typically the same.
Treatment approach
- Cold compresses and preservative-free artificial tears for comfort
- Topical antihistamine or mast-cell stabiliser eye drops for confirmed allergic conjunctivitis
- Oral antihistamines if paired with nasal symptoms
- Avoiding eye rubbing and reducing exposure to the confirmed trigger
