Cochrane: Are
treatments with eye drops of antihistamines and mast cell stabilisers,
alone or in combination, effective and safe in people with seasonal and
allergic conjunctivitis? The main
outcome
measure was eye symptoms reported by participants, including eye
itching, irritation (burning sensation), watering eyes (tearing), and
photophobia (dislike of light). We found 30 trials. Conjunctivitis refers to inflammation of the conjunctiva, which is the thin
tissue
that covers the sclera (white part of the eye). Seasonal and perennial
allergic conjunctivitis is the most common type of allergic
conjunctivitis. Although this condition does not cause sight loss, it
can cause intense itching and eye watering. Eye drops with
antihistamines or mast cell stabilisers, or both are commonly used.
