Diagnosing anemia via eye exam

Purdue University scientists have developed an inexpensive means for evaluating anemia from a smartphone photo of the eye.  To do this they created two algorithms, the first to turn a smartphone picture into a high-resolution digital image, and the second to analyze the tissue for hemoglobin.  “The team’s software was tested alongside blood tests and performed at a comparable level when measuring a range of blood hemoglobin values. It follows in the footsteps of similarly innovative approaches currently under development, including an app that measures hemoglobin in the finger using the phone’s flash, and another that does so through the fingernails.”  MORE
