University of Washington researchers have created a 3D-printed device that allows smartphones to accurately scan patients for signs of concussion or other traumatic brain injuries. The 3D-printed device, called PupilScreen, blocks out ambient light, allowing the accompanying app to scan a person's eye using a smartphone video camera and flash before analysing the footage. In this case, the pupillary light is blocked by an opaque plastic film on top of the phone's camera.

A pilot study showed early success, with the system able to correctly differentiate between patients with injuries and those without.
