Area of Science:

Ophthalmology
Cardiology
Medical Imaging
Artificial Intelligence

Background:

The retinal microvasculature serves as a critical indicator for cardiovascular diseases.
Current high-throughput tools for detailed retinal vessel analysis are insufficient.
Automated analysis of retinal vasculature is needed for early disease detection and monitoring.

Purpose of the Study:

To develop and validate an artificial intelligence system, the Retina-based Microvascular Health Assessment System (RMHAS).
To achieve fully automated vessel segmentation and quantification of the retinal microvasculature.
To establish a robust tool for predicting and monitoring cardiovascular diseases through retinal imaging.

Main Methods:

Development of the Retina-based Microvascular Health Assessment System (RMHAS) utilizing deep learning.
Validation of the system across diverse datasets including AV-WIDE, AVRDB, HRF, IOSTAR, LES-AV, and RITE.
Performance evaluation through segmentation accuracy (AUC), agreement, and repeatability analyses.

Main Results:

RMHAS demonstrated high segmentation accuracy for both arteries and veins across multiple datasets (AUCs ranging from 0.88 to 0.97).
The system showed robust performance, supported by agreement and repeatability analyses.
Quantitative vessel analysis was completed in under 2 seconds per case.

Conclusions:

The developed RMHAS provides accurate and efficient automated segmentation and quantification of retinal microvasculature.
This AI system holds significant potential for the early prediction and monitoring of cardiovascular diseases.
RMHAS offers a high-throughput solution for in-depth retinal vessel analysis, addressing a current gap in clinical tools.
