By looking through a patient’s widened pupil during a dilated eye exam, eye care professionals can view the retina—the postage stamp-sized tissue lining the back of the inner eye—and look for irregularities that may signal the development of vision loss. Thanks to research, retinal imaging just keeps getting better. The images above, which show the same cells viewed with two different microscopic techniques, provide good examples of how tweaking existing approaches can significantly improve our ability to visualize the retina’s two types of light-sensitive neurons: light-sensing, color-detecting cone cells (orange) and lowlight-sensing rod cells (blue).
