UBM Evaluation After Combined Deep Sclerectomy With Trabeculotomy in Primary Open Angle Glaucoma

Ultrasound Biomicroscopy Evaluation After Combined Deep Sclerectomy With Trabeculotomy in Primary Open Angle Glaucoma

Sponsor

Minia University Hospital

Enrollment

30 participants

Start Date

Nov 11, 2025

Study Type

OBSERVATIONAL

Conditions

Primary Open Angle Glaucoma (POAG)

Summary

Primary open-angle glaucoma is a chronic optic neuropathy that often requires surgical intervention when medical treatment fails. Deep sclerectomy is a non-penetrating glaucoma surgery that aims to reduce intraocular pressure while minimizing complications. When combined with trabeculotomy, additional aqueous outflow may be achieved. Ultrasound biomicroscopy (UBM) allows detailed imaging of the anterior segment and provides valuable information about postoperative anatomical changes that cannot be assessed clinically. This observational study aims to evaluate UBM findings after combined deep sclerectomy with trabeculotomy in patients with primary open-angle glaucoma and to correlate these findings with clinical outcomes.

Eligibility

Plain Language Summary

Simplified for easier understanding

This study uses a specialized ultrasound eye exam called ultrasound biomicroscopy (UBM) to look at the structures inside the eye after a combined glaucoma surgery (deep sclerectomy plus trabeculotomy) was performed together with cataract removal. The goal is to understand how these surgical areas heal and how well the drainage works over time. **You may be eligible if...** - You have been diagnosed with primary open-angle glaucoma (the most common type of glaucoma) - You have already had the combined cataract and glaucoma surgery described in this study - The inside of your eye is clear enough for the ultrasound imaging to work **You may NOT be eligible if...** - Your glaucoma is caused by another condition (such as inflammation, injury, or blood vessel problems) - You have had a previous glaucoma drainage surgery on the same eye - You have other eye conditions that interfere with the ultrasound imaging Talk to your doctor to see if this trial is right for you.

Interventions

DIAGNOSTIC_TESTUltrasound Biomicroscopy

Ultrasound biomicroscopy is performed as a non-invasive diagnostic imaging procedure to evaluate postoperative anterior segment anatomy, including intrascleral lake characteristics and filtering bleb morphology, in patients with primary open-angle glaucoma following combined deep sclerectomy with trabeculotomy.
