Summary

This study aims to find a blood marker that can tell how healthy the blood vessels in the eye are for people with diabetic retinopathy. Researchers will collect blood samples from 192 participants with type 2 diabetes and analyze special cells in the blood. The goal is to discover a way to monitor the condition without relying only on eye exams.
