The study developed RetiME, a deep learning biomarker built on foundation models that maps retinal photographs to mortality risk. It was trained on a European cohort and validated in three external cohorts in Southeast Asia, Eurasia and North America. RetiME was associated with all-cause and cause-specific mortality and predicted incidence of a range of systemic and ocular diseases. It also estimated each person's curve of mortality risk across future ages, which was associated with observed age at death. Clustering these curves gave cancer-predominant, cardiometabolic and neurodegenerative patterns. The model was trained on a single European cohort. The authors present it as only one component of a wider assessment of mortality risk.

*Why it is interesting: A cheap, non-invasive retinal photograph is linked to both the level of mortality risk and how it changes with age. External validation covered Southeast Asia, Eurasia and North America, and genome-wide analyses identified loci associated with the score.*
