The Eye-Brain Axis in High Myopia: From Retinal Deformation to Cortical Network Reorganization.
Review in Eye and brain, 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
High myopia is a major cause of irreversible visual impairment and is increasingly recognized as a condition involving interactions between ocular remodeling and central neural systems. This scoping review synthesizes current evidence on structural, functional, genetic, and regulatory links between the eye and brain in high myopia. We systematically searched PubMed and Web of Science from database inception to August 2026, identifying 54 eligible primary studies. The available evidence indicates that high myopia is associated with retinal and optic nerve abnormalities, altered white matter microstructure, occipital cortical changes, and functional reorganization across visual and higher-order brain networks. However, most neuroimaging evidence is cross-sectional, and Mendelian randomization analyses have not provided evidence for a clear causal effect of myopia on brain volumes. Genetic studies suggest modest overlap between refractive error and cognitive traits, whereas educational exposure appears to contribute causally to myopic refractive development. Experimental and observational evidence also supports reciprocal regulation of ocular growth through circadian, dopaminergic, autonomic, and behavioral pathways, although several proposed mechanisms remain incompletely established in humans. Overall, the eye-brain axis provides a useful integrative framework for understanding high myopia, but longitudinal and interventional studies are required to determine causal relationships and evaluate whether neural or behavioral targets can improve clinical outcomes.
