| spring conjunctivitis | A chronic, bilateral conjunctival inflammation with photophobia and intense itching that recurs seasonally during warm weather; characterised in the palpebral form by cobblestone papillae in the upper palpebral conjunctiva and in the bulbar form by gelatinous nodules adjacent to the corneoscleral limbus.
