Artificial intelligence based prediction of first recurrence in neovascular age related macular degeneration with validation by 19 experts
This analysis synthesizes research on leveraging AI to predict the first recurrence of neovascular age-related macular degeneration (nAMD), a major cause of vision loss. The study pitted a previously validated AI model against 19 ophthalmologists (retinal and non-retinal specialists) in predicting recurrence within three months using optical coherence tomography (OCT) images and clinical data. Findings reveal that while expert performance improves with more information, AI consistently demonstrates a strong predictive capability (AUROC 0.744), often surpassing unassisted human experts. Critically, AI assistance not only slightly improves expert prediction accuracy but also significantly enhances inter-reader agreement, leading to more standardized diagnostic interpretations. The insights underscore AI's potential to transform nAMD patient management by optimizing treatment strategies, improving counseling, and fostering more consistent clinical decision-making across diverse levels of experience.
Executive Impact: Revolutionizing Ocular Diagnostics
Artificial intelligence offers a transformative approach to early recurrence prediction in neovascular age-related macular degeneration (nAMD), promising significant improvements in diagnostic consistency and patient management. By providing objective insights, AI can empower clinicians to make more informed and timely treatment decisions, ultimately enhancing patient outcomes and operational efficiency within ophthalmology practices.

AI vs. Expert Prediction Accuracy
The AI model demonstrated superior predictive accuracy (AUROC 0.744) compared to unassisted human experts, whose performance improved significantly when supported by AI, reaching 0.679 in AI-assisted sessions. This highlights AI's potential to enhance diagnostic precision.
| Prediction Scenario | AI Model (AUROC) | Human Experts (AUROC) |
|---|---|---|
| Overall Performance | 0.744 | 0.679 (AI-assisted Session 5) |
| Baseline OCT Only | 0.600 | 0.562 (Session 1) |
| After Loading Phase OCT Only | 0.725 | 0.665 (Session 2) |
| AI Assistance Impact | N/A | Significantly improved performance (p < .05) in sessions 1, 3, 4 with AI support |
Enhancing Expert Consistency
AI significantly improved inter-reader agreement among ophthalmologists, standardizing interpretation. Key OCT biomarkers like subretinal hemorrhage and hyperreflective foci were critical for achieving good expert consensus on early recurrence.
Significant
Inter-reader Agreement Boost (p < 0.05)
AI assistance led to a statistically significant improvement in inter-reader agreement (p < .05 across most sessions), with the final AI-assisted session achieving a moderate Fleiss' kappa score. This underscores AI's role in standardizing interpretation of complex OCT images, regardless of an expert's clinical experience or subspecialty. Furthermore, the study highlighted specific OCT features, such as baseline subretinal hemorrhage and intraretinal hyper-reflective foci, as key biomarkers for achieving high inter-expert agreement in predicting early recurrence.
AI Model Prediction Process
The AI model employs a dual-step process: first, identifying fluid regions via a U-Net based segmentation, followed by classification using a ResNet50 network. An ensemble approach combines baseline and post-loading phase OCT image predictions for the final recurrence score and heatmaps.

Clinical Implications & Roadmap
AI holds promise for optimizing nAMD management by predicting recurrence, enabling proactive patient care, and standardizing OCT interpretation. Future efforts will involve multi-center validation and integrating more clinical variables for enhanced robustness.
AI for Optimized nAMD Management
This study demonstrates AI's potential as a valuable adjunct to clinical decision-making for neovascular age-related macular degeneration (nAMD). By predicting first recurrence within three months, the AI model can help clinicians optimize follow-up schedules and anti-VEGF therapy administration. Identifying higher-risk individuals earlier allows for proactive management, potentially preventing delayed detection of recurrent exudation and improving patient outcomes. The AI's ability to standardize OCT image interpretation also supports more consistent diagnostic criteria among ophthalmologists, bridging experience gaps. While the AI model achieved a moderate AUROC of 0.744, this level of accuracy still provides meaningful clinical value for triage and risk stratification. Future work will focus on external validation with multi-center datasets, developing models for actual recurrence time prediction, and incorporating relevant clinical variables for a more comprehensive evaluation, ultimately leading to more robust and generalized AI applications in ophthalmology. Key limitations include being a single-center study, a relatively small dataset, and the AI model relying solely on OCT images, suggesting future models should integrate clinical variables for a more comprehensive assessment.
