Patient quality of life after different glaucoma surgeries

Quality of Life After Glaucoma Surgery: Evaluating the Patient Perspective Across Surgical Options - G-SCOPE (Glaucoma Surgery - Comparative Patient Evaluation)

Observational Hospices Civils de Lyon · NCT07303257

This project uses the NEI-VFQ-25 vision questionnaire to see if adults who have PreserFlo MicroShunt, trabeculectomy, or non-penetrating deep sclerectomy report different quality of life after surgery.

What this trial studies

This observational study will collect patient-reported visual function using the NEI-VFQ-25 before and after glaucoma surgery to compare quality-of-life outcomes across surgical techniques. Eligible adults undergoing PreserFlo MicroShunt with mitomycin C, trabeculectomy with mitomycin C, or non-penetrating deep sclerectomy with mitomycin C will be enrolled at Hôpital de La Croix Rousse in Lyon. The protocol excludes congenital glaucoma, refractory cases with multiple prior surgeries, recent ophthalmic surgery within 6 months, and severe visual comorbidities. Data will be analyzed to identify differences in patient-reported outcomes across procedures and glaucoma subtypes.

Who should consider this trial

Good fit: Adults (≥18) with an indication for glaucoma surgery who are candidates for PreserFlo MicroShunt, trabeculectomy, or non-penetrating deep sclerectomy with mitomycin C—covering open-angle, angle-closure, pseudoexfoliative, pigmentary, and certain secondary glaucomas.

Not a fit: Patients with congenital glaucoma, refractory glaucoma after multiple prior surgeries, recent ophthalmic surgery within 6 months, severe retinal comorbidities, or who cannot attend follow-up visits are unlikely to be included or to benefit from this protocol.

Why it matters

Potential benefit: If successful, the findings could help surgeons and patients choose glaucoma surgery that better preserves day-to-day visual function and quality of life.

How similar studies have performed: Previous studies have measured quality of life after glaucoma procedures, but direct comparisons using the same questionnaire across PreserFlo, trabeculectomy, and non-penetrating sclerectomy are limited.
