Conjunctival erosion after glaucoma drainage device surgery: A feasible option

Abstract

Glaucoma drainage devices (GDDs) have been used in the management of complicated glaucomas. GDDs are associated with various complications such as tube migration, tube or plate exposure or extrusion, ocular motility disturbance and infection. Erosion of conjunctiva and exposure of the GDD remains a risk factor for the development of endophthalmitis. A wide range of materials have been used for this purpose, including sclera, dura, pericardium, fascia lata and cornea. However, there is no evidence to prove that any of these methods is superior to another for providing tectonic durability in the long term. In this report, we present a case of neovascular glaucoma, who developed conjunctival melting over the tube of an Ahmed Glaucoma Valve implant and was successfully managed with Cap Doxycycline.

Wound dehiscence and device migration after subconjuntival bevacizumab injection with ahmed glaucoma valve implantation

“…Mechanical rubbing of the eyelid margin against the patch graft, excessive conjunctival tension over the device, tube malposition, lack of a smooth tapered surface between the patch graft and the host with poor ocular lubrication, and even minute amounts of absolute alcohol retained in the donor sclera might cause these problems. [ 5 ] Tube exposure following conjunctival erosion with AGV implants appears to be a major risk factor for development of endophthalmitis. [ 3 ]…”

“…1) ) to the host conjunctiva with multiple interrupted non-absorbable sutures to ensure stability, vascularity and graft survival. Postoperatively she was started on oral doxycycline (100 mg twice daily for 6 weeks) to hasten conjunctival healing and prevent collegenolysis and conjunctival necrosis [ 3 ]. She presented 9 months later with 0.5 mm anterior conjunctival erosion and tube exposure (Figure 1d (Fig.…”

Safety and efficacy of Ahmed glaucoma valve implantation in refractory glaucomas in Northern Indian eyes

“…One patient with tube extrusion and conjunctival erosion required tube repositioning and reinforcement with a scleral patch. Another patient had conjunctival erosion and exposure of sclera patch graft which responded to conservative treatment with oral doxycycline, corticosteroids, and tear substitutes 19 . Two post-PK patients had tube-corneal touch in the early postoperative period.…”
