At Duke University, researchers are using infrared thermal imaging cameras for early glaucoma detection.  The camera captures an infrared image showing a close up detail of your tear duct canal where the water passes over the eye into the canal, this flow keeps a normal amount of pressure in the eye.  For patients suffering from glaucoma, these natural drainage channels collapse, building up fluid and creating pressure that can damage the optic nerve and lead to partial or complete blindness.

"The standard test for narrow-angle glaucoma can distort the natural shape of eye structures, making a diagnosis difficult" Asrani, a Duke ophthalmologist, said.

By using infrared cameras, ophthalmologist are now able to clearly see these canals and diagnose glaucoma early then previously available.
