Prototype Retina Camera Lowers the Lost with the Raspberry Pi #piday #raspberrypi @Raspberry_Pi

Researchers at the University of Illinois at Chicago College of Medicine and Massachusetts Eye and Ear/Harvard Medical School have developed a cheap, portable camera that can photograph the retina without the need for pupil-dilating eye drops. Made out of simple parts mostly available online, the camera’s total cost is about $185.
“As residents seeing patients in the hospital, there are often times when we are not allowed to dilate patients — neurosurgery patients for example,” said Dr. Bailey Shen, a second-year ophthalmology resident at the UIC College of Medicine. “Also, there are times when we find something abnormal in the back of the eye, but it is not practical to wheel the patient all the way over to the outpatient eye clinic just for a photograph.”
The prototype camera can be carried in your pocket, Shen said, and can take pictures of the back of the eye without eye drops. The pictures can be shared with other doctors, or attached to the patient’s medical record.
The camera is based on the Raspberry Pi 2 computer, a low-cost, single-board computer designed to teach children how to build and program computers. The board hooks up to a small, cheap infrared camera, and a dual infrared- and white-light-emitting diode. A handful of other components — a lens, a small display screen and several cables — make up the rest of the camera.
