1. A method for treating closed angle glaucoma, the method comprising:
- inserting into an eye a deployment device configured to hold an intraocular shunt, the device comprising a sleeve with a protrusion at a distal end of the sleeve, the protrusion (a) having a generally linear and generally rounded distalmost edge extending in a direction transverse to the longitudinal axis of the sleeve, and (b) protruding radially outwardly, relative to a longitudinal axis of the sleeve, from a portion of the sleeve proximal to the protrusion;
using the device to re-open an at least partially closed anterior chamber angle of an eye by moving the protrusion toward the anterior chamber angle; and
advancing the shunt from the device into eye tissue while the protrusion is in contact with tissue at the anterior chamber angle.

Abstract
The present invention generally relates to methods for treating closed angle glaucoma. In certain embodiments, methods of the invention involve inserting into an eye a deployment device configured to hold an intraocular shunt, using the device to re-open an at least partially closed anterior chamber angle of an eye, and deploying the shunt from the device.

7. A method for treating closed angle glaucoma, the method comprising:
-
inserting into an eye a deployment device (i) holding an intraocular shunt and (ii) comprising a sleeve, the sleeve comprising a wedge-shaped protrusion having a generally rounded edge extending transversely to a longitudinal axis of the sleeve at a distal end of the sleeve; re-opening an at least partially closed anterior chamber angle of an eye, the re-opening comprising advancing the protrusion toward an at least partially closed anterior chamber angle of the eye until the protrusion contacts tissue and then continuing advancement of the protrusion into the anterior chamber angle without entering tissue of the eye; and after advancing the protrusion fully into the anterior chamber angle, advancing the shunt relative to the sleeve into tissue of the eye. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15, 16)

17. A method for treating closed angle glaucoma, the method comprising:
-
inserting into an eye a deployment device (i) holding an intraocular shunt and (ii) comprising a sleeve, the sleeve having a lumen and a distal portion comprising a distal end of the sleeve, the lumen having a longitudinal axis, the distal portion comprising a wedge-shaped protrusion having a larger external dimension in a direction transverse to the longitudinal axis than has a portion of the sleeve proximal to the distal portion; re-opening an at least partially closed anterior chamber angle of an eye by advancing the distal portion into an at least partially closed anterior chamber angle of the eye; and with the protrusion fitted within the anterior chamber angle, advancing the shunt relative to the sleeve into tissue of the eye. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
