Smartphone-based device could detect retinopathy at home

University of California at Berkeley researchers have developed a smartphone-based device that examines the retina and acts as a user-friendly version of the optometrist’s ophthalmoscope. Daniel Fletcher and his students developed the handheld ophthalmoscope by pairing the imaging capabilities of a smartphone with software that is designed to examine the retina. “The advanced technology built
