A high-definition OCT image of the retina allows clinicians to non-invasively visualize the 3D structure of key regions, such as the macula (region near the fovea) and optic nerve head, to screen for signs of disease pathology. Shown here is a wide-field view (A) as well as detailed vertical cross-sections (B), (C) and (D) and a circular cross-section (E). (Credit: Biomedical Optics Express)

A new optical device puts the power to detect eye disease in the palm of a hand. The tool—about the size of a hand-held video camera—scans a patient’s entire retina in seconds and could aid primary care physicians in the early detection of...
