  • Publication number: 20230072025
    Abstract: Disclosed herein are systems and methods for stimulating meibomian gland epithelial cell function by administering to the ocular surface or immediate vicinity of an eye of a subject an effective amount of a pharmaceutical composition containing a PLD-inducing compound, such as the cationic amphiphilic drugs (e.g. azithromycin), androgen or an androgen analogue with androgen effectiveness, corticosteroid, progesterone, IGF-1 or an IGF-1 analogue (e.g. insulin), GH, and mixtures thereof. The pharmaceutical compositions are effective to treat a variety of aliments to the eye including meibomian gland dysfunction, evaporative dry eye disease, lipid abnormalities in meibum or the tear film, and autoimmune diseases such as Sjögren's syndrome.

  • Patent number: 11554048
    Abstract: Systems and methods of treating meibomian and sebaceous gland dysfunction. The methods include reducing oxygen concentration in the environment of one or more dysfunctional meibomian and sebaceous glands, thereby restoring a hypoxic status of one or more dysfunctional meibomian and sebaceous glands. The reducing of the oxygen concentration is accomplished by restricting blood flow to the one or more dysfunctional meibomian and sebaceous glands and the environment of one or more dysfunctional meibomian sebaceous glands. The restricting of the blood flow is accomplished by contracting or closing one or more blood vessels around the one or more dysfunctional meibomian or sebaceous glands. The methods also include giving local or systemic drugs that lead to the generation of hypoxia-inducible factors in one or more dysfunctional meibomian and sebaceous glands.

  • Patent number: 8945604
    Abstract: The present invention provides an ophthalmic device, and method of use thereof, for an individual wearing an ophthalmic lens to increase ocular surface boundary lubrication. The invention device comprises an ophthalmic lens and a sacrificial mechanism disposed on the ophthalmic lens, wherein the sacrificial mechanism comprises a plurality of surface bound receptors, such as PRG4, hyaluronic acid, and DNA aptamers, that reversibly bound to a lubricating composition comprising a gel forming agent, a surfactant, or a combination thereof, effectively inhibiting or preventing protein and lipid adsorption on the surface of the lens, and mitigate shear stress and reduce the friction between the lens and the ocular surface of the individual in need.
