Eureka!: Small Wonders

The eye inside

An image of the fundus, or the back of the eye.

Two UB ophthalmologists have been testing new ways to photograph something most of us have never seen: the fundus, or the back of the eye. Jiaxi Ding and Matthew Pihlblad snapped this image using a device called the iExaminer. The researchers showed that the handheld tool—which marries an iPhone to a lighted eye-exam instrument—is useful for capturing eye problems in patients who have a hard time sitting upright, as conventional fundus cameras require. The premature newborn whose fundus you see here is a perfect example.
