In this study, we present DiaNet, a novel multi-stage Convolutional Neural Network (CNN)-based model, designed to classify individuals as diabetic or non-diabetic solely based on their retinal fundus images. By leveraging transfer learning and fine-tuning CNN architectures across multiple datasets, our model effectively extracts discriminative features from retinal images, achieving an accuracy exceeding 94%. The methodology involves a multi-stage training approach, integrating retinal images from the QBB and EyePACS datasets to enhance the model’s robustness and generalizability. Furthermore, explainability techniques such as activation mapping reveal the specific retinal regions that contribute to classification decisions, corroborated by expert ophthalmologists. A comparative evaluation of DiaNet against conventional biomarker-based models highlights the ability of retinal imaging to serve as a reliable and scalable diagnostic modality. Additionally, findings suggest that subtle vascular anomalies in the retina may act as early prognostic indicators, not only for diabetes but for comorbidities like hypertension and ischemic heart disease. Given the cost-effectiveness and non-invasive nature of retinal imaging, our approach aligns with global health initiatives, including those advocated by the International Diabetes Federation (IDF) and the World Health Organization (WHO), aiming for low-cost, accessible diabetes screening solutions. The integration of DiaNet into clinical workflows has the potential to revolutionize diabetes screening, reducing physician workload in high-income nations and enhancing mass screening efficiency in low- and middle-income countries. This research underscores the importance of image-based AI-driven diagnostics and lays the groundwork for future advancements in automated medical imaging applications
