Described methods and compositions for treating Meibomian Gland Disease (MGD) for normalizing gland secretions and improving symptoms of ocular surface diseases associated with MGD. The methods concern treatment of a patient with aldosterone antagonists, such as spironolactone or analogues of spironolactone. Spironolactone is desirably added in a novel treatment composition, preferably in the form of an aqueous solution, emulsion or suspension in small but effective concentrations and in a novel vehicle that adds to the increased solubility of what previously was known to be an insoluble active agent. Moreover, it is believed that the specific lower but effective concentrations of spironolactone, and / or the pluronic vehicle of the treatment composition, permits optimal expression of essential lipids and upregulation of genes that control lipid production necessary to a more normalized lipid component of the tear film for the treatment and / or the prevention of signs and / or symptoms of MGD.
