Compositions and methods for the treatment of meibomian gland dysfunction
Described herein are compositions and methods for the treatment of meibomian gland dysfunction. Said compositions and methods comprise keratolytic agents, such as salicylic acid, selenium disulfide, or the like. Topical administration of said compositions to the eyelid margin or surrounding areas provides therapeutic benefit to patients suffering from meibomian gland dysfunction.
1. A method for opening a meibomian gland obstruction or improving the quality of meibum in an individual in need thereof, the method comprising topically administering to the eyelid of a subject a composition comprising a keratolytic agent and an ophthalmically or pharmaceutically acceptable vehicle or carrier, the composition being administered to the eyelid of the individual in a manner suitable to deliver the keratolytic agent to an eyelid margin of the individual.
2. The method of claim 1 , wherein the keratolytic agent is administered with an oleaginous base.
3. The method of claim 1 , wherein the keratolytic agent is administered to an eyelid margin of the subject.
4. The method of claim 1 , wherein the keratolytic agent is self-administered.
5. The method of claim 1 , wherein the keratolytic agent is administered by a healthcare professional or physician.
6. The method of claim 1 , wherein the keratolytic agent is administered in combination with an ophthalmically acceptable carrier.
7. The method of claim 1 , wherein the keratolytic agent is administered to the eyelid of the subject periodically.
8. The method of claim 7 , wherein the keratolytic agent is administered to the eyelid of the subject at least once a week.
9. The method of claim 1 , wherein improving the quality of the meibum comprises reducing a viscosity of the meibum.
10. The method of claim 1 , wherein improving the quality of the meibum comprises reducing the opacity of the meibum.
11. The method of claim 1 , wherein improving the quality of meibum comprises increasing an expressibility of meibum from a meibomian gland.
12. The method of claim 1 , wherein quality of meibum is determined by applying pressure to a meibomian gland, expressing meibum from the meibomian gland, and evaluating the quality of the meibum expressed from the meibomian gland.
13. The method of claim 1 , wherein improving the quality of the meibum comprises reducing an amount of particulate matter in the meibum.
14. The method of claim 13 , wherein the particulate matter comprises altered secretions and keratinized material.
15. The method of claim 1 , wherein the meibomian gland obstruction comprises one or more of chronic ocular discomfort, anatomic abnormalities around the meibomian gland orifice, obstruction of the meibomian glands, or decreased meibum production.
16. The method of claim 15 , wherein the anatomic abnormalities around the meibomian gland orifice comprise one or more of vascular engorgement, anterior or posterior displacement of the mucocutaneous junction, or irregularity of the eyelid margin.
17. The method of claim 1 , wherein the keratolytic agent is administered in a concentration greater than or equal to 0.1% by weight.
18. The method of claim 1 , wherein the keratolytic agent is an inorganic selenium compound.
19. The method of claim 18 , wherein the inorganic selenium compound is a selenium sulfide.
20. The method of claim 19 , wherein the selenium sulfide is selenium disulfide.
