Comparing healing effects of growth factor-rich plasma and autologous serum in aniridia patients

Comparison of the Healing Properties on Corneal Cells of Groth Factor-enriched Plasma and Autologous Serum From Aniridia Patients

Observational Fondation Ophtalmologique Adolphe de Rothschild · NCT05400590

This study is testing whether growth factor-rich plasma or autologous serum helps heal the eyes better in people with aniridia, a condition that causes corneal scarring.

What this trial studies

This study investigates the healing properties of growth factor-rich plasma versus autologous serum in patients with aniridia, a condition that leads to corneal scarring and clouding. Blood samples will be collected from both aniridia patients and healthy controls, with half used to create autologous serum and the other half for growth factor-rich plasma. The study aims to evaluate the in vitro healing and anti-fibrotic effects of these treatments by analyzing conjunctival impressions. The goal is to determine which treatment may better promote epithelial healing and reduce fibrosis.

Who should consider this trial

Good fit: Ideal candidates include patients diagnosed with aniridia who meet specific weight and health criteria.

Not a fit: Patients with insufficient sample volume or those with unconfirmed genetic aniridia may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a more effective treatment option for improving corneal healing in aniridia patients.

How similar studies have performed: While the use of autologous serum is common, the specific comparison of growth factor-rich plasma in this context is novel and has not been extensively tested.
