Beschreibung
Inclusion Criteria:
- • Diagnosis of advanced or refractory primary open-angle glaucoma (POAG) or secondary open-angle glaucoma (excluding neovascular glaucoma).
- Intraocular pressure (IOP) > 21 mmHg despite maximal tolerated medical therapy or previous failed glaucoma surgery.
- Best corrected visual acuity (BCVA) of 20/400 or better.
- Capable of providing informed consent
Exclusion Criteria:
- Previous incisional glaucoma surgery in the study eye (except for prior failed trabeculectomy in the refractory group).
- Neovascular glaucoma or other forms of secondary glaucoma that may significantly impact wound healing (e.g., uveitic glaucoma).
- Significant ocular comorbidities that may confound outcome assessment (e.g., severe corneal disease, retinal detachment).
- Pregnancy or lactation.
- Participation in another clinical trial within 30 days prior to enrollment.

|---|---|

Experimental: Arm 1: Innovative Tube Trabeculectomy (ITT)
Patients will undergo the innovative tube trabeculectomy procedure.
This includes a 3-week preoperative regimen (discontinuation of preserved medications and prostaglandin analogs, initiation of fluorometholone), a 1-week preoperative subconjunctival injection (Mitomycin C 0.04%, Avastin 1.25 mg, Dexamethasone 8 mg), and the surgical technique involving a deep extended scleral tunnel, intraoperative Mitomycin C application, X-shaped non-absorbable suture, and nasolacrimal tube implantation.

Aktiver Komparator: Arm 2: Conventional Trabeculectomy
Patients will undergo standard conventional trabeculectomy with intraoperative Mitomycin C application (concentration and duration as per standard practice at the study site).
