Analyzing eye fluid biomarkers in patients with retinal diseases

Analysis of Biomarkers From Patients With Chorioretinal Diseases

Observational Kyungpook National University Hospital · NCT02026843

This study is trying to see if certain eye fluids can help us understand how serious retinal diseases like diabetic retinopathy and age-related macular degeneration are in patients.

What this trial studies

This observational study investigates ocular biomarkers in patients suffering from chorioretinal diseases such as diabetic retinopathy and age-related macular degeneration. It includes a total of 100 participants, with 50 patients diagnosed with chorioretinal diseases and 50 control patients undergoing cataract surgery or vitrectomy. Ocular fluids and blood samples are collected prior to treatment to analyze the levels of specific biomarkers. The goal is to better understand the relationship between these biomarkers and the severity of retinal diseases.

Who should consider this trial

Good fit: Ideal candidates are adults over 20 years with chorioretinal diseases or those requiring cataract surgery.

Not a fit: Patients under 20 years or those with recent ocular trauma or infections may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved diagnostic and therapeutic strategies for patients with chorioretinal diseases.

How similar studies have performed: Other studies have shown promise in analyzing ocular biomarkers for retinal diseases, suggesting this approach has potential.
