The Eyes Have It - Diagnosing Diabetes Through The Eyes
Iridology has been practiced for 450 years, and is still considered to be a pseudoscience by the establishment. The idea that the eyes can show what is happening in your body is not one that rests well with the conventional medical community, who prefer to use expensive, invasive, and often extensive testing in order to come up with a diagnosis.
But now, researchers from the Queensland University of Technology, in Australia, and the University of Manchester, in the UK, are suggesting that maybe these kooky iridologists are onto something. In a recent article, the team announced that a person's cornea can show whether or not a person has diabetes.
Put simply, excess blood sugar reduces blood flow, and reduced blood flow damages peripheral nerves. Since the cornea is the most innervated tissue in the body, it follows that if there's any nerve damage, you should be able to see some there. Sure enough, the team has found that people with diabetes have - on average - fewer and shorter nerve fibers than other people.
What remains is the development of a reliable clinical test based on this research. The most common test for diabetes at the moment is the fasting plasma glucose test (FPG), which requires the subject to fast for eight hours prior to giving a blood sample, which is then sent to the lab for testing.
The corneal research team is developing a test that simply requires you to sit in front of a corneal confocal microscope. Using their own software, they have introduced the test in several hospitals, where it appears to be working well.
Mind you, iridologists could probably have told them all about this beforehand, and saved them all that work:
