Conjunctival erosion after glaucoma drainage device surgery: a feasible option

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.
