Deep Learning-Derived Retinal Age Detects Cognitive Impairment.
Article in Ophthalmology science, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Purpose: To investigate the association between deep learning-derived retinal age and cognitive function and to evaluate whether retinal age outperforms chronological age as a screening tool for cognitive impairment. Design: Cross-sectional analysis of the data from multicenter Artificial Intelligence-Ready and Exploratory Atlas for Diabetes Insights (AI-READI). Participants: We included 1049 participants (≥40 years) (mean [standard deviation] chronological age, 60.3 [11.2] years) enrolled in the AI-READI cohort, a multicenter, cross-sectional study. Methods: Retinal age was estimated from color fundus photographs using a pretrained deep learning model. Cognitive function was assessed using the Montreal Cognitive Assessment (MoCA), with cognitive impairment defined as a MoCA score <26. Generalized linear models were used to compare MoCA scores across retinal age quartiles. Poisson regression and logistic regression were used to evaluate the association between retinal age and cognitive impairment, adjusting for chronological age and cardiometabolic risk factors. Main Outcome Measures: Retinal age, MoCA scores, and cognitive impairment. Results: Retinal age correlated more strongly with MoCA total score than chronological age (R, -0.47 vs. -0.21). Retinal age was associated with cognitive impairment in a dose-response manner with adjusted risk ratio (RR) of 2.81, 6.03, and 10.13 for the second, third, and fourth quartiles in comparison to the first quartile of retinal age (all Conclusions: Deep learning-derived retinal age is a biological biomarker that significantly outperforms chronological age in its association with cognitive function and has better performance in detecting cognitive impairment. This scalable, image-based biomarker has the potential for opportunistic screening within existing clinical workflows, facilitating earlier detection of cognitive decline.
