Topical ophthalmic compositions and methods for treating dry eye are described. The compositions and methods of the invention are based on the finding that the oculosurface selective properties of the glucocorticoid rimexolone make this anti-inflammatory agent particularly well-suited for treating dry eye. As a result of the limited ability of rimexolone to penetrate the cornea, a high portion of the drug remains on the surface of the eye, which is the primary locus of the inflammatory conditions associated with dry eye. This enables a very low concentration of drug to be utilized, which in turn reduces the potential for elevations of intraocular pressure and cataract formation.
