Comparing two methods of glaucoma drainage device placement

Glaucoma Drainage Device and Endothelial Cell Density Loss Compare (DECLARE) Trial

NIH-funded research University of California, San Francisco · NIH-11074588

This study is looking at how the placement of glaucoma drainage devices affects eye health, specifically focusing on which method helps keep your eye pressure stable while causing less harm to the cells in your cornea, and it's for people with glaucoma who might need this type of surgery.

What this research studies

This research investigates the effects of two different placements of glaucoma drainage devices (GDD) on corneal endothelial cell loss and other surgical outcomes. Patients will be randomly assigned to receive either a tube placed in the anterior chamber or in the ciliary sulcus. The study aims to determine which placement method results in better control of intraocular pressure and minimizes damage to the corneal cells. By analyzing data from 240 participants across multiple centers, the research seeks to provide clearer guidance on the optimal surgical technique for managing glaucoma.

Who could benefit from this research

Good fit: Ideal candidates for this research are individuals diagnosed with medically uncontrolled glaucoma who are considering glaucoma drainage device surgery.

Not a fit: Patients with well-controlled glaucoma or those who are not candidates for surgical intervention may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to improved surgical techniques that preserve corneal health and enhance the quality of life for glaucoma patients.

How similar studies have performed: Previous studies have shown mixed results regarding the outcomes of different GDD placements, indicating that this research could provide valuable new insights.
