Retina Image Comparison (IMAGE) Duke University Caption A comparison of retinal images taken by the new low-cost OCT system (left) and a commercial device built by Heidelberg Engineering (right). In its first clinical trial, the low-cost system produced images of 120 retinas that were 95 percent as sharp as those taken by current commercial systems, which was sufficient for accurate clinical diagnosis.
