Chorioretinal Folds Following Glaucoma Valve Implantation

Ophthalmic Surgery, Lasers and Imaging Retina, 1998
Abstract. Glaucoma valve implants have been observed to cause scleral indentation and flattening. The authors report the case of a 79-year-old woman who had previously undergone glaucoma valve implantation, and who subsequently developed chorioretinal folds that corresponded to the implant in location and configuration. Accumulation of fluid behind the

Novel Micromachined Valved Glaucoma Drainage Devices

2006 International Conference of the IEEE Engineering in Medicine and Biology Society, 2006
In this work two novel valve devices are proposed for treatment of glaucoma. By opening or closing, the proposed valves can be used to reduce high pressures in the eye (hypertony), or prevent low pressures in the eye (hypotony) respectively. These devices work based on the buckling of fluid channel connected to the anterior chamber of the eye.

Ahmed glaucoma valve implantation in uveitic glaucoma versus open-angle glaucoma patients

Canadian Journal of Ophthalmology, 2008
The poor long-term success rate of repeat trabeculectomies in refractory uveitic glaucoma (UG) patients has led to the use of glaucoma drainage devices (GDDs). However, the success and complication rates of GDDs in UG patients utilizing a control group with standard demographic data, design, and surgical technique have never been evaluated.Fifteen ...

Ahmed glaucoma valve in vitrectomized eyes: An implantation technique to minimize early postoperative fluid-loss hypotony

European Journal of Ophthalmology, 2021
Purpose: To describe the application of a modified Ahmed glaucoma valve (AGV) surgical implantation technique in vitrectomized eyes, in order to minimize the risk of early postoperative hypotony, which leads to hemorrhagic complications.

Results of Ahmed glaucoma valve implantation in primary congenital glaucoma

Journal of American Association for Pediatric Ophthalmology and Strabismus, 2014
To evaluate the outcome of Ahmed glaucoma valve (AGV) implantation in primary congenital glaucoma (PCG).The medical records of patients with PCG refractory to trabeculotomy and medical therapy who had undergone AGV implantation with a minimum follow-up of 6 months were retrospectively reviewed.
