Retinal connections to migraine.
Review in Frontiers in neurology. 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
Objective: This narrative review aims to examine potential associations between migraine and retinal disorders, with particular attention to retinal migraine, age-related macular degeneration (AMD), retinal vascular occlusions, and photophobia. Background: The role of retinal pathways in migraine pathophysiology remains poorly understood. As a component of the central nervous system, the retina provides a unique and accessible window into neuronal structure and function. Emerging observations suggest that structural and functional retinal changes may occur in individuals with migraine; however, their relevance and consistency across studies remain uncertain. Results: Visual phenomena are characteristic of migraine aura, yet the extent to which migraine affects retinal structure and function is still unclear. Retinal migraine, while suggestive of a direct retinal involvement, is rare and insufficiently characterized to support mechanistic conclusions. Epidemiological data indicate that individuals with migraine may have an increased risk of neovascular AMD, raising the possibility of shared pathogenic pathways. In addition, photophobia, retinal artery occlusion, and alterations in retinal nerve fiber layer thickness have been reported more frequently in migraine patients than in controls, although causality has not been established. Mechanisms implicated in AMD, including microvascular dysfunction, impaired DNA damage response, disrupted autophagy, and mitochondrial dysregulation, have also been proposed in migraine, but evidence remains limited. Conclusion: Migraine has been linked to several retinal conditions, with AMD showing the most consistent association. While overlapping biological processes are suggested, further studies are needed to clarify their significance and determine whether retinal alterations contribute to migraine pathophysiology or represent secondary phenomena.
