Allergic conjunctivitis is one of the most common allergic conditions
worldwide. Its incidence is increasing due to changing climate, pollution,
increased pollen loads, and the subject’s heightened immunological
sensitivity in response to these environmental changes.
The most common clinical presentations of ocular allergy are
conjunctival hyperaemia (redness) and chemosis (swelling), itching and
tearing and vision loss in severe cases.
