Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Tube Shunt Surgery Group | Participants in this group will receive a tube shunt surgery (Baerveldt Glaucoma implant).~Tube shunt surgery: The procedure involves implantation of a Baerveldt consisting of a tube that is connected to an end plate. The tube is inserted into the anterior chamber and shunts aqueous humor to the end plate located in the equatorial region of the eye. The aqueous humor is then absorbed by the tissues around the eye. | 21 | 125 | OG000 |
| Group 2 | Trabeculectomy With Mitomycin C | Participants in this group will receive a Trabeculectomy surgery with Mitomycin C~Trabeculectomy: The procedure involves removal of a small portion of trabecular meshwork and adjacent tissue under a partial thickness scleral flap. Aqueous humor drains into the subconjunctival space producing a filtering bleb. The aqueous humor then diffuse out of the bleb.~Mitomycin C: A fluid retaining sponge soaked in 0.4 mg/ml Mitomycin C will be applied in the region of Trabeculectomy site for about 2 minutes | 12 | 117 | OG001 |
