Investigating genetic factors in different types of glaucoma
Official title: Investigating the Genetic Basis of Pseudoexfoliation Syndrome, Angle-closure Glaucoma and Primary Open-angle Glaucoma
Run by Medical University of Vienna · NCT03423758 · Data updated 2026-11-12
This study is trying to find out if certain genes are linked to different types of glaucoma by looking at blood samples from patients with these conditions and healthy people.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include individuals aged 21 and older with confirmed diagnoses of PXF, PACG, or POAG, as well as healthy controls over 60 years old.
✕Probably not a fit
Patients without any form of glaucoma or significant ocular diseases may not benefit from this study.

What this trial studies
This observational study aims to identify genetic risk factors associated with pseudoexfoliation syndrome (PXF), primary angle closure glaucoma (PACG), and primary open-angle glaucoma (POAG) using a whole genome association approach. By analyzing blood samples from patients with these conditions and healthy controls, the study seeks to uncover susceptibility genes that may play a role in the development of glaucoma. The findings could enhance understanding of ocular development and lead to improved diagnostic and prognostic tools for these glaucoma types.
Why it matters
Potential benefit: If successful, this research could lead to better diagnostic tests and treatment strategies for glaucoma patients.
How similar studies have gone: Previous studies have shown promise in identifying genetic factors related to glaucoma, suggesting that this approach may yield valuable insights.
