Clinical trials are underway to help analyze the gait of glaucoma patients and compare them to those without the eye condition. 

Developed by Washington State University researchers, the trial involves sensors worn on special shoes that can detect the length and evenness of a step, as well as the equity between the feet. 

By detecting changes and abnormalities in the way a person walks, the analysis could provide an early indication of glaucoma’s presence and could also prevent serious injury from falls.
