Disclosed is an agent for the treatment of dry eye, which is characterized by combining a P2Y2 receptor agonist at a therapeutically effective concentration with hyaluronic acid or a salt thereof at a therapeutically effective concentration. This agent for the treatment of dry eye, which is in the form of an ophthalmic agent, remarkably promotes tear secretion and remarkably improves corneal epithelial disorder, and is thus expected to be a novel agent for the treatment of dry eye.
