The role of glaucoma drainage devices (GDDs) for refractory glaucoma is well established because of certain advantages offered over conventional filtering surgeries. However, the correct plane of placement of the GDD tube inside an eye with an opaque cornea can be challenging, due to poor intra-operative visualization. These cases are also challenging if they undergo subsequent corneal grafting. In cases with presence of totally opaque cornea precluding tube visualization within the anterior chamber, we describe a novel technique for ensuring the correct positioning of a GDD tube.

Precis: Glaucoma surgery impacts corneal graft survival differently by procedure type, with GDDs being most effective at reducing intraocular pressure. However, graft survival rates are comparable across trabeculectomy, CPC, and GDDs. Trabeculectomy improves visual acuity best but often requires additional interventions.

Precis: Second trabeculectomy and glaucoma drainage device implantation offer similar success rates for juvenile open angle glaucoma after initial trabeculectomy failure. However, second trabeculectomies required fewer medications. A quarter of patients in both groups required a third operation after 2.

Glaucoma drainage devices (GDD) are used for patients with secondary glaucoma, such as uveitic or neovascular glaucoma, which is uncontrolled under local therapy. They are also used in patients with conjunctival scarring, for example after a previous vitrectomy or after unsuccessful previous glaucoma surgery, such as trabeculectomy. They are also a treatment option for congenital glaucoma, aphakic glaucoma or for the treatment of iridocorneoendothelial syndromes.

Aim And Background: To describe a novel and uncomplicated technique of elongating the tubing of a glaucoma drainage device (GDD) sourced from a segment of the tube from a Paul® Glaucoma Implant (PGI).
Surgical Technique: Conjunctival and Tenon's peritomy are performed with relaxing incisions to expose the original tube. The original tube is then removed from the anterior chamber, and the original entry site is closed.
