New technology could see a tiny sensor implanted in the eye that removes the need for people with diabetes to test blood glucose daily.
The sensor, which is smaller than a grain of rice, may include a special chemical that creates a fluorescent light upon contact with glucose . When blood glucose levels are high, the light could shine more powerfully. The exact nature of the device remains to be seen.
This type of light cannot be seen by the naked eye, yet a small handheld device could convert the light level into glucose measurements. The new implant could render uncomfortable finger-pricking unnecessary. The eye sensor is being pioneered by a German company called EyeSense. Diabetes UK warned that the technology is at an early stage.
