The incidence of Alzheimer’s disease continues to grow exponentially, with some estimating it will affect more than 78 million people worldwide by 2030. However, imaging studies of brain aging have mostly been limited to neuroimaging, specifically MRI. Due to the cost associated with MRI, researchers have recognized retinal imaging to be a powerful, non-invasive and inexpensive way to study the brain via the eye. A new study in American Journal of Ophthalmology investigated how the outer retina in those with age-related macular degeneration would correlate with brain changes associated with Alzheimer’s. The findings reveal that a thinner outer retina was associated with the brain regions involved in memory. Read More
