Combination treatment using ELT
A method of treating a subject having glaucoma comprises performing excimer laser trabeculostomy (ELT) on a subject having glaucoma and having previously undergone a failed treatment or a treatment that has been rendered ineffective by progression of the disease. In some examples, the failed treatment is a non-surgical treatment comprising administering medicated eye drops. In some examples, the failed treatment is a laser treatment or surgical treatment, such as a trabeculoplasty, iridotomy, iridectomy, trabeculectomy, trabeculotomy, goniotomy, surgical insertion of a shunt or implant, deep sclerectomy, viscocanalostomy, or a combination thereof.
1. A method of treating a subject having glaucoma comprising:
performing excimer laser trabeculostomy (ELT) on the subject having the glaucoma, wherein the subject has previously undergone one or more failed treatments for the glaucoma and the ELT is performed after the one or more failed treatments have been attempted with the subject, wherein the one or more failed treatments comprises at least one of a surgical eye treatment or a laser eye treatment.
2. The method of claim 1 , wherein the one or more failed treatments further comprises a non-surgical treatment comprising administering medicated eye drops.
3. The method of claim 2 , wherein the medicated eye drops comprise alpha agonists, beta blockers, carbonic anhydrase inhibitors, cholinergic agonists, prostaglandin/prostamide analogues, or a combination thereof.
4. The method of claim 1 , wherein the one or more failed treatments is the laser eye treatment.
5. The method of claim 4 , wherein the laser eye treatment comprises non-invasive laser trabeculoplasty, iridotomy, iridectomy, or a combination thereof.
6. The method of claim 5 , wherein the trabeculoplasty comprises selective laser trabeculoplasty (SLT).
7. The method of claim 1 , wherein the one or more failed treatments is the surgical eye treatment.
8. The method of claim 7 , wherein the surgical eye treatment comprises insertion of a shunt or implant, trabeculectomy, trabeculotomy, goniotomy, deep sclerectomy, viscocanalostomy, or a combination thereof.
9. The method of claim 1 , wherein performing ELT comprises:
inserting a fiber probe into an eye of the subject;
adjusting placement of the fiber probe in the eye; and
applying a plurality of shots from an excimer laser.
10. The method of claim 9 , wherein the excimer laser is a xenon chloride laser.
11. The method of claim 9 , wherein placement of the fiber probe is in a position transverse to Schlemm's canal in the eye.
12. The method of claim 11 , wherein a light source aids in adjusting placement of the fiber probe.
13. The method of claim 12 , wherein the light source is a Gonio lens, endoscope, or other illumination source.
14. The method of claim 9 , further comprising administering anesthesia to the subject before inserting the fiber probe.
15. The method of claim 9 , further comprising post-operative analysis comprising visualizing drainage of aqueous humor and bloody reflux flowing from Schlemm's canal in the eye.
