Thinner Retina a Sign of Cognitive Decline

We know that people with dementia typically have a thin retinal nerve fiber layer (RNFL) when we test them using optical coherence tomography (OCT) during their eye exam. Researcher reporting the results of a large study in JAMA Neurology found a significant association between RNFL thickness and cognitive function even when dementia had not yet been diagnosed. In fact, they found that those people in the bottom 20% of RNFL thickness were twice as likely to suffer cognitive decline over the next three years! This is the first study to identify that a thin RNFL indicates a risk of future cognitive decline and suggests that regular eye tests could help identify those likely to get dementia at a much earlier stage, which means suitable treatments could be prescribed at a more effective time to slow or stop the onset of dementia at early stages of the disease.
