NCT02653963

Brief Summary

This triple-blind, stratified, randomized clinical trial includes 100 eyes of 100 patients aged 18 to 85 years with refractory glaucoma. Eligible subjects undergo stratified block randomization; eyes are first stratified to one of four subgroups: group 1:patients with previous failed trabeculectomy, group 2: uveitic glaucoma, group 3: neovascular glaucoma and group 4: other indications like aphakic glaucoma or glaucoma associated with vitreoretinal procedures. In each subgroup, eyes are randomly assigned to the study arms using random blocks: conventional Ahmed Glaucoma Valve (AGV) implantation (group A, 50 eyes), Ahmed Glaucoma Valve (AGV) with intraoperative periplate triamcinolone injection (group B, 50 eyes). Patients will be followed for one year. They will undergo full ophthalmology examination at first day, first week, month 1, 3, 6, 9 and 12 after the surgery. The primary outcome measure is cumulative probability of success, defined as intraocular pressure (IOP) of 6-21 mm Hg, with or without medication, and no serious complications, additional glaucoma surgery, or loss of light perception. The outcomes will be compared between two arms in each subgroup. The number of eyes requiring medications, time to initiation of medications, and number of medications will be compared.

Outcome Measures

Primary Outcomes (1)

  • INTRAOCULAR PRESSURE

    Intraocular pressure (IOP) of 6-21 mm Hg, with or without medication, and no serious complication

    1, 3, 6 ,9 and 12 month

Secondary Outcomes (2)

  • Anti-glaucoma drug number

    1, 3, 6 ,9 and 12 month

  • Visual acuity

    1, 3, 6 ,9 and 12 month

Study Arms (2)

Conventional AGV

NO INTERVENTION

A limbus-based conjunctival peritomy was created 4mm posterior to the limbus and Tenon's capsule was dissected. The AGV Plate was secured to the sclera 8 mm posterior to the limbus. The tube was trimmed to an appropriate length and inserted into the anterior chamber through a corneoscleral track. The tube was fixed to the episclera with a 10-0 nylon mattress suture. A donor sclera was fashioned to cover the exposed part of the tube and was secured to the sclera using 10-0 nylon sutures. The conjunctiva and Tenon were closed using 10-0 nylon suture.

Triamcinolone adjuctival AGV

EXPERIMENTAL

Subtenon Periplate 10 mg triamcinolone acetonide around the AGV plate after fixation of AGV Plate to the sclera

Drug: Adjunctival Triamcinolone

Interventions

Intraoperative Periplate 10 mg Triamcinolone Injection during AGV Implantation

Also known as: Intraoperative steroid
Triamcinolone adjuctival AGV

Eligibility Criteria

Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Eligible subjects were patients aged 18-85 years with refractory glaucoma scheduled for AGV implantation.
