Multi-class eye disease classification using deep learning EfficientNetB0 fusion techniques
This research introduces a novel dual-backbone deep learning (DL) framework for multi-class eye disease classification, combining EfficientNetB0 with ResNet50, InceptionV3, and AlexNet through various fusion strategies. The system achieves high accuracy, particularly with concatenation and weighted fusion techniques, demonstrating strong generalization across internal and external datasets (Messidor-2 and ODIR). Explainability analysis using Score-CAM confirms that model decisions align with clinical understanding of disease-relevant anatomical features, proving robustness for real-world clinical deployment.

Clinical Interpretability with Score-CAM
Understanding Model Decisions for Eye Disease Diagnosis
The study utilized Score-CAM to visualize which parts of the retina the model focused on for diagnosis. For Diabetic Retinopathy (DR), heatmaps highlighted the optic disc, macula, and main blood vessels. Glaucoma models concentrated on the optic nerve head, aligning with actual structural changes. Cataract models focused on lens denseness, matching the overall haze. Normal retinal images showed balanced attention across key anatomical points. This strong alignment with traditional medical checkup standards proves that the model decisions are based on pathophysiologically relevant features, enhancing trust and readiness for clinical deployment.
Conclusion: The explainability confirms the model's understanding of disease pathophysiology, crucial for clinical acceptance and adoption.
