The study reports high diagnostic accuracy for AI systems in detecting DR, with pooled sensitivity of 0.877 (95% CI: 0.870–0.884) and specificity of 0.906 (95% CI: 0.904–0.908). This indicates strong performance in identifying both true positives and true negatives, outperforming traditional clinician sensitivity (0.751). Heterogeneity was noted, primarily due to variations in AI models and datasets.
AI systems significantly enhance disease detection, with a positive AI result increasing the post-test probability of DR to 84.92%. This positions AI as an effective tool for triaging patients, enabling ophthalmologists to focus on high-risk cases. The Fagan nomogram analysis confirms the strong diagnostic value in clinical practice.
AI-based DR screening demonstrates significant cost-effectiveness, particularly in resource-constrained environments. Studies indicate that AI can increase quality-adjusted life years (QALYs) at a lower incremental cost compared to traditional methods, facilitating broader access to screening and reducing the economic burden of vision loss.
Despite strong performance, the study acknowledges high heterogeneity across studies and potential publication bias, which may limit generalizability. Future research needs to standardize AI evaluation metrics and dataset diversity. The review also highlights the need for further analysis of patient demographics (age, sex, disease duration) as potential sources of heterogeneity.

AI Diagnostic Odds Ratio (DOR) - High discriminative power for DR
AI in Rural China: A Cost-Effective Solution
A Markov model analysis in rural China showed AI screening significantly increased quality-adjusted life years (QALYs) by 0.16 at an incremental cost of $180.19. This was well below the cost-effectiveness threshold of one to three times the per capita GDP, demonstrating AI's feasibility in resource-constrained settings and its potential to alleviate the economic burden of vision loss.
