Evaluating visual field changes after PreserFlo MicroShunt implantation for glaucoma

Visual Field Progression and RNFL Change After PreserFlo MicroShunt Implantation - a Prospective Cohort Study at the Ophthalmology Department Klinikum Klagenfurt

Observational Klinikum Klagenfurt am Wörthersee · NCT06174324

This study is testing how well the PreserFlo MicroShunt surgery helps improve vision and eye health in people with glaucoma who aren't getting enough relief from other treatments.

What this trial studies

This observational study aims to assess the progression of visual fields and changes in retinal nerve fiber layer (RNFL) thickness following the implantation of the PreserFlo MicroShunt in patients with glaucoma. The study will focus on patients who have not achieved adequate intraocular pressure control despite existing treatments. By monitoring structural and functional changes post-implantation, the research seeks to provide insights into the effectiveness of this surgical approach compared to traditional methods like trabeculectomy.

Who should consider this trial

Good fit: Ideal candidates include patients with primary open angle glaucoma, pseudoexfoliation glaucoma, pigment dispersion glaucoma, or normal tension glaucoma who have insufficient eye pressure control.

Not a fit: Patients who have previously undergone glaucoma surgery or have severe visual impairment may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved management of glaucoma with reduced risk of complications and better preservation of vision.

How similar studies have performed: Other studies have shown promising results with similar surgical approaches, indicating potential for success in this area.
