Wider retinal venules linked to lower IQ scores, both as adults and retrospectively in childhood.
It's another link between venous drainage of the eye or brain and cognitive functioning.

The findings suggest that the processes linking vascular health and cognitive functioning begin much earlier than previously assumed, years before the onset of dementia and other age-related declines in brain functioning.
The current study doesn’t address the specific mechanisms that drive the relationship between retinal vessels and cognitive functioning, but the researchers surmise that it may have to do with oxygen supply to the brain.
