SwinCup-DiscNet: A fusion transformer framework for glaucoma diagnosis using optic disc and cup features
Glaucoma is a leading cause of permanent visual disability. Early detection is crucial. This paper introduces SwinCup-DiscNet, a novel fusion transformer framework that integrates optic disc/cup and feature-based segmentation with global feature learning for effective glaucoma screening. It combines an Attention U-Net for precise OD/OC boundary extraction with a Swin Transformer encoder for global feature analysis. The framework uses a probabilistic fusion of the vertical Cup-to-Disc Ratio (vCDR) and deep learning features for final classification. Evaluated on LAG, ACRIMA, and DRISTHI-GS datasets, SwinCup-DiscNet consistently outperforms traditional CNN-based and segmentation-only models, showing robustness, reliability, and clinical interpretability.

Understand the real-world implications of SwinCup-DiscNet, including its ability to minimize false positives and provide clinically interpretable results, enhancing early glaucoma detection.
Enhanced Glaucoma Detection in Real-World Settings
SwinCup-DiscNet's fusion approach significantly reduces false positives by leveraging both global retinal context and structural biomarkers. This robust performance, especially in borderline cases, makes it a highly effective clinical tool for early glaucoma detection, weighing sensitivity over specificity in screening scenarios.
- Reduced false positives in cases with large optic cups or ambiguous disc morphology.
- Improved segmentation accuracy despite imaging artifacts like non-uniform light or vessel overlap.
- Balances global retinal context with structural biomarkers for robust decision-making.
- Clinically interpretable outcomes, aligning with real-world screening practices.
