According to the World Health Organization, glaucoma is the second leading cause of blindness worldwide, after cataracts. Studies suggest that the disease damages eyesight due to sudden spikes in intra-eye pressure, which affect the optic nerve.
To measure the pressure inside their eyes, glaucoma patients typically make a trip to the doctor’s office once or twice a year. This is hardly enough, opines Hyuck Choo, from the California Institute of Technology (Caltech) in Pasadena.
Choo, who is an assistant professor in the Division of Engineering and Applied Science at the institute, wanted to provide glaucoma patients with “a way to measure their eye pressure easily and regularly,” states a Caltech news release.
