Treating the ocular symptoms of seasonal allergic rhinitis with triamcinolone acetonide aqueous nasal spray.

摘要

Allergic rhinitis (AR) is one of the most prevalent chronic diseases worldwide, with an estimated 20% of the global population thought to be affected. Ocular symptoms (eg, itching, tearing, and redness) are commonly bothersome components of AR and when present together with nasal symptoms are more properly termed allergic rhinoconjunctivitis. Although intranasal corticosteroids (INSs) are the most effective treatment option for controlling the inflammatory responses associated with AR, oral antihistamines have been the most commonly used rescue medication when not being used for prevention for allergic rhinoconjunctivitis. Recent evidence has suggested that INSs may have the potential to reduce ocular symptoms. The mechanism for this effect is unclear; several theories suggest modulation of a naso-ocular neurogenic reflex or nasolacrimal reflux.
