Investigating inflammatory markers in glaucoma after corneal transplantation

Uncovering Inflammatory Mediators of Glaucoma Pathogenesis After Corneal Transplantation in Aqueous Humor and Tears

Not applicable Interventional Centre hospitalier de l'Université de Montréal (CHUM) · NCT04339907

This study is trying to find out if certain markers in the tears and eye fluid of people who have had corneal transplants can help spot early signs of glaucoma.

What this trial studies

This study aims to explore the role of inflammatory mediators in the aqueous humor and tears of patients who have undergone corneal transplantation, particularly focusing on those with glaucoma. By sampling these fluids, researchers hope to identify potential biomarkers that could indicate early signs of glaucoma development or progression. The study includes various patient groups, including those with and without glaucoma, and those who have had different types of corneal surgeries. The ultimate goal is to better understand the mechanisms behind glaucoma in these patients and improve treatment strategies.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with specific ocular conditions related to glaucoma and corneal transplantation.

Not a fit: Patients under 18 or those with ocular diseases not specified in the study criteria may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to earlier detection and better management of glaucoma in patients who have undergone corneal transplantation.

How similar studies have performed: While the specific approach of using inflammatory biomarkers in this context may be novel, similar studies have shown promise in understanding glaucoma and its progression.
