Explantation of the novel Ahmed glaucoma valve M4 implant.
Summary
If necessary, AGV M4 explantation can be successfully performed in the early postoperative period.
Abstract
PURPOSE
To report a series of cases involving Ahmed Glaucoma Valve M4 (AGV) explantation and to discuss the surgical technique to remove the drainage device.
METHODS
Four cases were identified that presented with AGV M4 postoperative complications necessitating tube shunt removal. Three patients presented with conjunctival erosion and 1 patient with persistent diplopia. AGV M4 implants were removed successfully between 1.5 and 9 months after implantation.
RESULTS
Successful explantation of the AGV M4 novel implant was achieved in all cases without intraoperative or postoperative complications.
CONCLUSIONS
If necessary, AGV M4 explantation can be successfully performed in the early postoperative period.
