Investigating glucose control and biomarkers in diabetic retinopathy

Dynamic Parameters of Glucose Control in Relation to Biomarkers in Serum and Intraocular Fluid in Diabetic Patients With Ocular Complications

Charles University, Czech Republic · NCT05944640

This study is testing if monitoring glucose levels and eye fluid can help find new ways to prevent and treat diabetic retinopathy for people with diabetes.

What this trial studies

This project explores the characteristics of diabetic retinopathy by utilizing liquid eye biopsy alongside continuous glucose monitoring to assess glucose variability. The study aims to identify biomarkers related to miRNAs and inflammatory chemokines that may influence the development and progression of diabetic retinopathy. By understanding these relationships, the research seeks to inform new screening, diagnostic, and treatment strategies for patients, ultimately improving prevention and early intervention efforts. The findings could lead to enhanced quality of life for patients and reduced healthcare costs associated with advanced retinopathy.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with type 1 or type 2 diabetes who have been on insulin for at least five years and have any form of diabetic retinopathy.

Not a fit: Patients with active intraocular inflammation, uncontrolled glaucoma, or recent intravitreal therapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved screening and treatment strategies for diabetic retinopathy, enhancing patient outcomes.

How similar studies have performed: While the approach of combining liquid biopsy with glucose monitoring is innovative, similar studies have shown promise in understanding diabetic complications, suggesting potential for success.
