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

About this study
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.
Interventions
- Diagnostic Test: Ultrasound 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.
Primary outcomes
- Intrascleral lake area on ultrasound biomicroscopy (UBM) (3 and 6 months postoperatively)
- Intrascleral lake height on ultrasound biomicroscopy (UBM) (3 and 6 months postoperatively)
- Filtering bleb height on ultrasound biomicroscopy (UBM) (3 and 6 months postoperatively)
- Filtering bleb internal reflectivity on ultrasound biomicroscopy (UBM) (3 and 6 months postoperatively)
