Eligibility Criteria:
Inclusion criteria~* Briefly, the diagnosis of glaucoma is based on the presence of 2 or more of the following findings: 1) glaucomatous optic disc damage, defined as the presence of optic disc excavation, diffuse or focal neuroretinal rim thinning or notching, localized or generalized retinal nerve fiber layer (RNFL) thinning; 2) visual field defects consistent with glaucoma; and 3) IOP ≥ 22 mmHg.~* Patients with glaucoma who have been advised to undergo TCNR of a failed trabeculectomy bleb by a glaucoma specialist at Northwestern Medicine~* History of failed trabeculectomy (based on clinical features of the trabeculectomy bleb and elevated intraocular pressure)~* Patients can have history of other glaucoma surgery or cataract surgery~* The diagnosis of glaucoma is based on the presence of 2 or more of the following findings: 1) glaucomatous optic disc damage, defined as the presence of optic disc excavation, diffuse or focal neuroretinal rim thinning or notching, localized or generalized RNFL thinning; 2) visual field defects consistent with glaucoma; and 3) IOP ≥ 22 mmHg.~Exclusion criteria~* Age younger than 18 years;~* Secondary causes of glaucoma (e.g., iridocyclitis, trauma);~* Any evidence of corneal or conjunctival pathology adjacent to filtration bleb that could influence AS-OCT image~* Patients who did not undergo surgery or have adequate follow up~* Adults unable to consent, individuals who are not yet adults (infants, children, teenagers), pregnant women, prisoners and vulnerable populations

Study Arms:
- AS-OCT and iOCT (Type: OTHER): This prospective study will include approximately 25 patients with open-angle glaucoma who will undergo TCNR of trabeculectomy bleb by a glaucoma specialist at Northwestern Medicine. These patients will have a history of glaucoma and failed trabeculectomy bleb (as evidenced by clinical features and elevated IOP). During routine clinic visit, the patient will undergo lit lamp grading of bleb by Indiana Bleb Appearance Grading Score (IBAGS). Subjects who agree to participate and provide written informed consent will undergo AS-OCT imaging (Spectralis OCT, Heidelberg) of the bleb. During their operation, the Zeiss Artevo digital microscope integrated with iOCT (Zeiss Artevo 800, Carl Zeiss Meditec AG), a commercially available device will be utilized to visualize and evaluate the morphology of the trabeculectomy bleb at the start and conclusion of the case.

Based on this trial design, predict the completion outcome and termination type (if applicable).
