Abstract

An object of the present invention is to discover a new medicinal use of 5-[4-[[3-methyl-4-oxo-3,4-dihydro-2-quinazolinyl]methoxy]p henylmethyl]thiazolidine-2,4-dione and N-[(4-methoxyphenoxy)carbonyl]-N-[[4-[2-(5-methyl-2-phenyl-4-oxazolyl)ethoxy]phenyl]methyl]glycine. Both of the compounds exert an excellent improving effect on corneal disorder models and is useful as a therapeutic agent for a keratoconjunctival disorder such as dry eyes, corneal ulcer, keratitis, conjunctivitis, superficial punctate keratopathy, corneal epithelial defects, conjunctive epithelial defects, keratoconjunctivitis sicca, superior limbic keratoconjunctivitis and filamentary keratitis.
