Dynamic Light Scattering Technology
dynamic light scattering technology Did you know that for every tissue type in the body there is a corresponding tissue in the eye? Someday, doctors may be able to diagnose all sorts of diseases simply by measuring subtle irregularities in the tissues, fluids and blood vessels of our eyes without a prick, prod or poke thanks to NASA research.

NASA's Glenn Research Center first investigated dynamic light scattering technology as a method for early detection of cataracts, a degenerative eye disease that can affect astronauts who are exposed to radiation during long space missions.

Today, the National Institutes of Health are testing the device for clinical effectiveness in early cataract diagnosis for patients on Earth. Eventually, doctors also could use it to it to detect and monitor treatment for Alzheimer's disease, age-related macular degeneration, diabetic retinopathy, pigment dispersion glaucoma and corneal disease.
