Abstract

A novel ring-shaped device inserted into the conjunctival sac of an animal eye exhibits potential for prolonged release of therapeutic drugs to the eye region. Its prolonged retention properties render it suitable for use in the extended treatment of obstinate ocular infections, such as infectious bovine keratoconjunctivitis in cattle.
