If Professor Brent Cameron has his way, people with diabetes will soon be able to measure their blood glucose by simply shining a light into their eye.
Pricked fingers, lancets, and glucose monitors that need blood will become a thing of the past. Professor Cameron has invented a glucose-testing device based upon the fact that the aqueous humor of the eye, which is the liquid between the cornea and the lens, contains glucose in the same concentration as blood.
His device uses polarized light that shines through the aqueous humor. The glucose in the aqueous humor causes the polarized light to rotate in proportion to the concentration of glucose in the liquid. The amount of rotation is then measured to give a reading of the level of blood glucose.
The invention has been licensed to a California-based company, Freedom Meditech, which plans to build the device into something about the size of a pair of binoculars, take it through FDA trials, and then develop it commercially. Freedom Meditech expects to have the device on the market in three to five years.
