Strabismus After Ahmed Glaucoma Valve Implantation

American Journal of Ophthalmology, 2021
Most reports of strabismus after glaucoma drainage device implantation study larger devices and rarely note the incidence of strabismus after Ahmed glaucoma valve (AGV) implantation. It is unknown if the pattern of strabismus is similar with smaller devices.

A Modification of the Ahmed Valve for Tight Places

Ophthalmic Surgery, Lasers and Imaging Retina, 2003
Abstract. The availability of adequate conjunctival tissue is essential for successful implantation of glaucoma valves. This report describes a technique to place a trimmed Ahmed valve in an eye with limited subconjunctival space due to systemic disease and multiple previous surgical procedures, including a scierai buckle.

Valve Membrane Adhesion as a Cause of Ahmed Glaucoma Valve Failure

Journal of Glaucoma, 1997
The purpose of this study was to describe a possible mechanism of failure of the Ahmed glaucoma valve (AGV; New World Medical, Rancho Cucamonga, CA).Two AGVS that failed to control intraocular pressure (IOP) were examined. In vivo examination consisted of unroofing the capsule surrounding the implant and injecting fluorescein-stained balanced salt ...

Proline-assisted Tube Insertion Through Sulcus in Ahmed Valve.

Journal of glaucoma, 2020
To prevent corneal endothelial cell loss, ciliary sulcus tube insertion is preferred for the pseudophakic eye. However, we sometimes encounter technical difficulties when inserting the tube through the sulcus. Even in cases in which we are able to insert

Second Ahmed Valve Insertion in the Same Eye

Journal of Glaucoma, 2009
To examine the results of same-eye second Ahmed glaucoma drainage device (GDD) insertion in eyes with refractory glaucoma despite previous Ahmed GDD insertion and maximal tolerated medical therapy.Noncomparative retrospective case series.Twenty-one patients who had undergone 2 GDD surgeries in the same eye were identified.
