Abstract: The present disclosure relates to a composition for preventing, alleviating or treating an eye disease, which contains (7S)-(+)-cyclopentylcarbarmic acid, 8,8-dimethyl-2-oxo-6,7-dihydro-2H,8H-pyrano[3,2-g]chromen-7-yl-ester as an active ingredient. The (7S)-(+)-cyclopentylcarbarmic acid, 8,8-dimethyl-2-oxo-6,7-dihydro-2H,8H-pyrano[3,2-g]chromen-7-yl-ester of the present disclosure exhibits the effect of remarkably reducing intraocular vascular leakage and, as such, can be advantageously used in a composition for preventing, alleviating or treating an eye disease.
