Diagnostic accuracy of AI or DL-enhanced technologies in the diagnosis of diabetic retinopathy: a systematic review
Diabetic retinopathy (DR) is a major cause of preventable blindness globally, particularly in individuals with long-standing diabetes. Traditional screening methods are labor-intensive, time-consuming, and subject to variability. This systematic review evaluates the diagnostic accuracy of AI and deep learning (DL) models for DR detection, with a focus on hybrid architectures, aiming to improve early detection and clinical integration.
Key Findings & Impact Metrics
This systematic review, encompassing 20 high-quality studies from 2019-2024, confirms the significant clinical value of AI and DL in early DR detection and grading. Hybrid AI models, integrating CNNs, ViTs, and ensemble classifiers, consistently outperform conventional approaches, achieving superior generalizability and interpretability. Key findings include high diagnostic accuracy, cost-effectiveness, and the potential for transforming DR screening, especially in high-prevalence regions like Qatar and the Middle East, despite challenges in data diversity and regulatory compliance.

Real-world Applicability of AI in DR Screening
Mobile and cloud-based AI platforms, such as Efficient-NetB0 and ResViT Fusion Net, have shown practical success in decentralized screening programs. These systems enable outreach in remote populations and enhance triage and referral speed, demonstrating the practical impact of AI in low-resource settings. Integration of explainability tools like Grad-CAM and LIME further builds trust and clinician adoption.
