Handheld Device Takes High-Resolution Images

Caption

An image of a retina taken with the new handheld probe. The tiny white dots are photoreceptors called cones, which were not visible with previous handheld technologies. The concentrated circular area is called the fovea. It is believed that, as the eye matures, photoreceptors migrate to this area, making it much more densely populated than others.
