Cognitive link to early age-related macular degeneration

Early age-related macular degeneration is associated with cognitive impairment, say US researchers.

Their study in 2,088 people aged 69 to 97 years evaluated their cognitive function and dementia, and also assessed signs of early AMD using retinal photographs. After controlling for other factors – including age – those with the lowest cognitive scores had a 38% increased risk of early AMD.
