Summary

Researchers evaluated a deep learning-based glaucoma risk assessment (GRA) model, initially trained on national "All of Us" data, for its ability to identify high-probability glaucoma patients using only systemic electronic health records (EHR) at an independent institution. In a cross-sectional study, 20,636 Stanford patients seen from November 2013 to January 2024 were included, with 15% having glaucoma. The pretrained GRA model was fine-tuned on the Stanford cohort, using demographics, systemic diagnoses, medications, laboratory results, and physical examination measurements as inputs. The best model achieved an AUROC of 0.883 and a Positive Predictive Value (PPV) of 0.657. Calibration was strong, with the highest prediction decile showing a 65.7% glaucoma diagnosis rate and a 57.0% treatment rate. Performance improved with more trainable layers (up to 15) and additional data.

Key takeaway

For healthcare providers and AI scientists developing diagnostic tools, this study demonstrates that an EHR-only deep learning model can effectively identify patients at high risk for glaucoma. You should consider integrating such models for scalable and accessible pre-screening, potentially reducing the need for immediate specialized imaging and streamlining patient triage in ophthalmology.
