Background:

Corneal diseases affect millions globally, with endothelial dysfunction a primary cause of blindness.
Current diagnostic methods for corneal endothelial abnormalities lack sensitivity for early detection.

Purpose of the Study:

To introduce a novel, sensitive, image-based diagnostic framework for evaluating corneal endothelial cell function.
To develop a new functional metric, the Xin-Value (XV), for single-cell level assessment.
To improve the accuracy of grading endothelial damage.

Main Methods:

Developed a machine learning-based image recognition system to digitize cellular features.
Applied geometric and mathematical principles to establish the Xin-Value (XV) as a functional metric.
Validated XV against mitochondrial function and stress markers in corneal endothelial injury models.

Main Results:

The Xin-Value (XV) strongly correlated with biological markers of mitochondrial function and stress.
A refined grading system using XV demonstrated improved diagnostic accuracy among clinicians.
The framework enables highly sensitive, single-cell level detection of early endothelial dysfunction.

Conclusions:

Introduced a paradigm shift in corneal endothelial assessment with the novel Xin-Value (XV).
The developed framework provides a sensitive, image-based tool for early detection and monitoring of corneal endothelial dysfunction.
Potential clinical applications include screening and disease progression monitoring.
