Application Number:US17/933,471
Patent Claims: 1. A method for reducing corneal and/or conjunctival inflammation, the method comprising the step of topically administering to a human patient in need thereof an ophthalmic composition consisting of cyclosporine, 1-perfluorobutylpentane, 2-perfluorobutylpentane, and ethanol; wherein the cyclosporine is present in an amount of 0.1% (w/v), the 1-perfluorobutylpentane is present in an amount of at least 97% (w/w), the 2-perfluorobutylpentane is present in an amount of up to 2% (w/w), and the ethanol is present in an amount of up to 1.0% (w/w); wherein the composition is administered twice per day per eye as a single drop having a volume of about 10 μl.

2. The method according to claim 1, further comprising measuring inflammation; wherein the corneal inflammation is measured by fluorescein staining and the conjunctival inflammation is measured by lissamine green staining.

3. The method according to claim 1, wherein the method is a method for reducing corneal inflammation in the patient in need thereof.

4. The method according to claim 1, wherein the method is a method for reducing conjunctival inflammation in a patient in need thereof.

5. The method according to claim 1, wherein the patient is not responsive to treatment with artificial tears.

6. The method according to claim 1, wherein the patient has at least one eye with: a. a score of >40 on the dryness visual analogue scale (VAS); b. a total corneal fluorescein staining score of >6; c. a total lissamine green conjunctival staining score of >2; or d. a Schirmer's Test I score >2 mm and <8 mm.

7. The method according to claim 3, wherein the patient has at least one eye with: a. a total corneal fluorescein staining score of at least 6; or b. a central corneal fluorescein staining score of at least 1.

8. The method according to claim 4, wherein the patient has at least one eye with a total lissamine green conjunctival staining score of at least 2.

9. The method according to claim 1, wherein the patient has dry eye disease.

10. The method according to claim 1, wherein the patient has moderate to severe dry eye disease.

11. The method according to claim 1, wherein the patient has moderate to severe dry eye disease characterized by at least one or a combination of the following: a. a total corneal fluorescein staining score of >6; b. being symptomatic with a score of >40 on the dryness visual analogue scale (VAS); c. a score >20 on the Ocular Surface Disease Index (OSDI); or d. a Schirmer's Test I score of >2 mm and <8 mm.

12. The method according to claim 1, wherein the amount of cyclosporine administered in a single dose per eye is about 10 μg and wherein the total daily dosage of cyclosporine administered per eye is about 20 μg.

13. The method according to claim 1, wherein the 2-perfluorobutylpentane is present in an amount selected from the group consisting of up to 1% (w/w) and up to 0.5% (w/w).

14. The method according to claim 7, wherein the patient has dry eye disease.

15. The method according to claim 8, wherein the patient has dry eye disease.

16. The method according to claim 13, wherein the patient has dry eye disease.
