Examining the link between blood markers and eye blood flow in diabetic patients

Correlation of Biochemical Indexes and Retinal Hemodynamic in Patients With Different Degrees of Diabetic Retinopathy

The Seventh Affiliated Hospital of Sun Yat-sen University · NCT05902650

This study looks at how certain blood markers relate to blood flow in the eyes of people with diabetes to help predict the risk of diabetic retinopathy.

What this trial studies

This observational study focuses on diabetic patients at the Department of Ophthalmology of the Seventh Affiliated Hospital of Sun Yat-sen University. It collects OCTA data and biochemical indexes to develop a prediction model for diabetic retinopathy using the random forest method to identify sensitive indicators. The goal is to better understand how these factors correlate with different degrees of diabetic retinopathy.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals with a clinical diagnosis of diabetes.

Not a fit: Patients with other retinal diseases or those who have undergone intraocular surgery may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved early detection and management of diabetic retinopathy in patients.

How similar studies have performed: While similar studies have explored the relationship between biochemical markers and diabetic retinopathy, this specific approach using random forest modeling is relatively novel.
