Electron microscopic evaluation of a gold glaucoma micro shunt after explantation.

Unlabelled: We present a case of an explanted gold glaucoma micro shunt (GMS Plus) and the subsequent light and electron microscopic analyses. The shunt was implanted in a patient with medically refractive glaucoma. The intraocular pressure (IOP) was stable at 12 mm Hg 6 months postoperatively but spiked to 26 mm Hg 6 months later; membranous growth was visible on the implant gonioscopically.

Malignant glaucoma after cataract surgery.

Purpose: To report a series of eyes that developed malignant glaucoma after cataract surgery.

Setting: Private academic practice, Toronto, Ontario, Canada.

Design: Retrospective case series.

Nd: YAG laser goniopuncture: indications and procedure.

Laser goniopuncture is a complementary adjunct to nonfiltering glaucoma surgery such as deep sclerectomy, viscocanalostomy, and canaloplasty, contributing to intraocular pressure control and the avoidance of additional incisional surgery. Goniopuncture is associated with a low complication rate and demonstrates minimal inflammation, hemorrhage, and hypotony when performed correctly. This article provides a detailed description of how to perform this procedure and methods of preventing and addressing complications.

The phaco hemi-flip: a method of lens removal in nuclei of soft to moderate density.

Although endocapsular nuclear fragmentation chopping techniques have allowed surgeons to decrease the amount of dissipated phaco energy in the anterior chamber and improve lens removal efficiency when compared with previous techniques, chopping maneuvers carry a small risk of capsular and zonular injury. Furthermore, in softer lenses, chopping techniques may be limited in providing sufficient nuclear cracking. Additionally, with torsional phaco technologies, adequate lens purchase may be suboptimal and lead to inefficient chopping.

Late bleb leak management with trabeculectomy shutdown, Baerveldt glaucoma device implantation, and titratable tube lumen size.

Purpose: To report a case of late subconjunctival bleb leak, and its management to preserve vision and achieve optimal pressure control in a patient with advanced glaucoma, a 3+ Seidel positive bleb leak, and hypotony maculopathy in the better-seeing eye.

Design: Case Report.

Methods: Shutdown of the earlier trabeculectomy site with a scleral graft was achieved before insertion of a 250-mm Baerveldt glaucoma device.

The clear corneal tongue: a mechanism for wound incompetence after phacoemulsification.

Purpose: To describe a mechanism for wound incompetence after phacoemulsification with corneal incisions resulting in early postoperative wound leakage.

Design: Observational case series.

Methods: Three patients who had uneventful phacoemulsification through a clear corneal incision were identified because of a postoperative wound leak.
