Topology-preserving, diameter-specific framework for conjunctival vessel segmentation and tortuosity analysis in diabetes.

Analyzing eye vessel patterns from simple external photos can detect microscopic blood vessel damage in diabetes without expensive equipment, potentially enabling screening in resource-limited settings.

A novel topology-preserving deep learning framework enables accurate conjunctival vessel segmentation and tortuosity quantification in diabetes, demonstrating significantly elevated vessel tortuosity versus healthy controls using only external eye imaging. Conjunctival imaging may offer a scalable, non-invasive, slit-lamp-free tool for systemic microvascular phenotyping in diabetes.
