A programme of clinical studies was carried out to determine the basic efficacy and safety of 2% nedocromil sodium eye drops (Tilavist) in treating allergic conjunctivitis, in 2,905 patients from 3-76 years of age. Results of all the double-masked placebo comparative studies completed to date-five in vernal keratoconjunctivitis (VKC), five in perennial (PAC) and 16 in seasonal allergic conjunctivitis (SAC)-have been assessed in a statistical overview analysis. Nedocromil sodium, administered four times daily to 153 patients with VKC, was significantly more effective than placebo (155 patients) and in the clinicians' opinion gave good control in 76% of cases, compared with 46% for placebo (p < 0.001). Patients with chronic symptoms of PAC also responded better to nedocromil sodium given four times daily (n = 146) rather than twice daily (n = 86), and significantly more patients (p < 0.001) were effectively controlled by four times daily treatment with nedocromil sodium (72%) than with placebo (47%; n = 156). Twice-daily dosage with nedocromil sodium (n = 677) was adequate for SAC, however, and the treatment was statistically better than placebo (p < 0.01-p < 0.001) whether dosed twice or four times daily. Speed of action was assessed in seven SAC studies in which 79% of all patients (n = 295) using nedocromil sodium had experienced relief of symptoms when questioned, half of them within 15 minutes and 74% during the first hour after dosing. Test treatments were well-accepted by both adults and children, and there were no major adverse events. Minor irritations reported more frequently with nedocromil sodium than placebo were stinging or burning of the eyes on application of the drops and a distinctive taste, noted by 5% of the active treatment group (n = 1,552).

Ocular allergic disorders can be a component of systemic or local allergies. The importance of ocular allergy results from its incidence rather than from its severity, however, some of them are vision-threatening. The majority of ocular allergies affect the conjunctiva, eyelids and sometimes cornea that is exposed to the environment and is the place of interaction between allergens and immunocompetent cells. Different types of allergic disorders in the eye may have similar signs and symptoms, but each has its own pathognomonic characteristics, which help to diagnose, differentiate and choose the most suitable therapy. Ocular allergic diseases are classified into six categories: SAC, PAC, VKC, AKC, GPC and ConBC. In 2001 EAACI suggested new classification, also of allergic conjunctivitis, into IgE-mediated and non-IgE-mediated conjunctivitis. IgE-mediated conjunctivitis may be divided into intermittent and persistent conjunctivitis. Persistent allergic conjunctivitis is classified into vernal and atopic keratoconjunctivitis. Conjunctivitis contact allergy is a non-IgE form of allergic conjunctivitis. Currently available medications provide safe and effective management of most cases of ocular allergy. Drugs used in the treatment of ocular allergic disorders include mast cell stabilizers, antihistamines, steroids, NSAID's, artificial tears and others.
