    Retinal texture could provide early biomarker of Alzheimer's disease

    Biomedical engineers at Duke University have devised a new imaging device capable of measuring both the thickness and texture of the various layers of the retina at the back of the eye. The advance could be used to detect a biomarker of Alzheimer's disease, potentially offering a widespread early warning system for the disease. The results appear online on May 13 in the journal Scientific Reports . "Previous research has seen a thinning of the retina in Alzheimer's patients, but by adding a light-scattering technique to the measurement, we've found that the retinal nerve fiber layer is also ...

    1. Previous research has seen a thinning of the retina in Alzheimer's patients, but by adding a light-scattering technique to the measurement, we've found that the retinal nerve fiber layer is also rougher and more disordered...Our hope is that we can use this insight to create an easy and cheap screening device that wouldn't only be available at your doctor's office, but at places like your local pharmacy as well
