Method for treating filtration failure after trabeculectomy surgery
The current invention relates to the improvement of trabeculectomy surgery. The improvement more specifically resides in an extended lifetime of the sclera-corneal drainage channel created by trabeculectomy surgery. The improvement is obtained by post-surgical administration of a plasmin or active derivative thereof in the form of topical eye drops alone, by anterior chamber injection alone, or by any combination of these.
1. A method for treating filtration failure after trabeculectomy surgery of an eye of a human subject, the method comprising administering to the eye of the subject an effective amount of plasmin or an active truncated variant thereof.
2. The method of claim 1 , wherein the plasmin or the active truncated variant thereof is in a pharmaceutically acceptable formulation administered to the eye as topical eye drops.
3. The method of claim 1 , wherein the plasmin or the active truncated variant thereof is in a pharmaceutically acceptable formulation administered into the anterior chamber of the eye by injection.
4. The method of claim 1 , wherein the plasmin or the active truncated variant thereof is administered both by using topical eye drops comprising the plasmin or the active truncated variant thereof and by introduction of the plasmin or the active truncated variant thereof into the anterior chamber of the eye.
5. The method of claim 1 , wherein the active truncated variant of plasmin lacks one or more kringle domains.
6. The method of claim 1 , wherein the active truncated variant of plasmin is selected from the group consisting of midiplasmin, miniplasmin, microplasmin, and deltaplasmin.
7. The method of claim 1 , wherein the trabeculectomy surgery is performed to treat glaucoma in the eye of the subject.
8. The method of claim 1 , wherein an effective amount of microplasmin is administered to the eye of the subject.
9. The method of claim 7 , wherein an effective amount of microplasmin is administered to the eye of the subject.
10. The method of claim 1 , wherein the plasmin or the active truncated version thereof is in a pharmaceutically acceptable formulation further comprising an agent selected from the group consisting of an agent for controlling the intra-ocular pressure, an anti-inflammatory agent, an antiviral agent, an antibacterial agent, an anti-angiogenic agent, an anti-mitotic agent, an antihistamine, an anesthetic, an agent that induces mydriasis, and an agent that induces cycloplegia.
11. The method of claim 1 , wherein the active truncated variant of plasmin lacks parts of one or more kringle domains.
12. A method for reducing the occurrence of filtration failure after trabeculectomy surgery of an eye of a human subject, the method comprising administering to the eye of the subject an effective amount of plasmin or an active truncated variant thereof.
13. The method of claim 12 , wherein the plasmin or the active truncated variant thereof is in a pharmaceutically acceptable formulation administered to the eye as topical eye drops.
14. The method of claim 12 , wherein the plasmin or the active truncated variant thereof is in a pharmaceutically acceptable formulation administered into the anterior chamber of the eye by injection.
15. The method of claim 12 , wherein the plasmin or the active truncated variant thereof is administered both by using topical eye drops comprising the plasmin or the active truncated variant thereof and by introduction of the plasmin or the active truncated variant thereof into the anterior chamber of the eye.
16. The method of claim 12 , wherein the active truncated variant of plasmin lacks one or more kringle domains.
17. The method of claim 12 , wherein the active truncated variant of plasmin lacks parts of one or more kringle domains.
18. The method of claim 12 , wherein the active truncated variant of plasmin is selected from the group consisting of midiplasmin, miniplasmin, microplasmin, and deltaplasmin.
19. The method of claim 12 , wherein the plasmin or the active truncated version thereof is in a pharmaceutically acceptable formulation further comprising an agent selected from the group consisting of an agent for controlling the intra-ocular pressure, an anti-inflammatory agent, an antiviral agent, an antibacterial agent, an antiviral agent, an anti-angiogenic agent, an anti-mitotic agent, an antihistamine, an anesthetic, an agent that induces mydriasis, and an agent that induces cycloplegia.
20. The method of claim 12 , wherein the trabeculectomy surgery is performed to treat glaucoma in the eye of the subject.
21. The method of claim 12 , wherein an effective amount of microplasmin is administered to the eye of the subject.
22. The method of claim 20 , wherein an effective amount of microplasmin is administered to the eye of the subject.
