In a study conducted on 12 rabbits these investigators showed that the levels of glucose in tears correlated with glucose levels in the blood. People with diabetes are known to have too much glucose in the blood , can be caused by the pancreas stops producing insulin or the cells in the body that are resistant to insulin. This condition makes the body unable to absorb sugar from the bloodstream."People with diabetes need to measure many times his blood sugar levels, because its value can change throughout the day," said
Dr. George Grunberger of the American Association of Clinical Endocrinologists, as quoted by LiveScience , Friday (11/11/2011). In this study Jeffrey LaBelle, biomedical engineers from Arizona State University in collaboration with researchers at the Mayo Clinic to develop technology in tear glucose monitoring. goal is to make sensors that can be touched in the eye white for 5 seconds and then pressed into a device that is designed to read glucose levels.
This test may have the advantage of convenience rather than blood tests. level of glucose in tears known to 30 times lower than in the blood, for that the experts are developing sensors that can work with very sensitive so it can generate accurate data on the small amount of fluid. " The main challenge is evaporation, lower concentrations, and glucose include stress responder, which means it is difficult to get accurate pembacan if the eyes are under stress, "says LaBelle.
That requires a highly sensitive sensor, and a certain ratio between glucose in blood and tears that anybody can calibrate the sensor to tears of blood glucose levels.
