Rice bioengineering students' invention may help diagnose painful eye condition
Date:4/25/2011

Rice University bioengineering students responded to an ophthalmologist's cry for help with a device to diagnose dry eye, the itching and burning sensation that results when a person doesn't produce enough tears or the tears evaporate too quickly.

A team of five seniors made a portable unit that controls the air around a patient's eyes so doctors can study and treat those who suffer from this painful condition.

Stephen Pflugfelder, the James and Margaret Elkins Chair and professor of ophthalmology at Baylor College of Medicine's Cullen Eye Institute, approached Rice to invent a device to help clinicians standardize a testing regime for dry eye.

"He wanted a way to control temperature, humidity and air flow all around the eyes and record it over time so he could track changes in their dryness," said Daniel Hays, a member of Team ClimaTears, the student group that included Austin Edwards, Amanda Shih, Anastasia Alex and Michelle Kerkstra.

The students' solution incorporates a modified and padded set of laboratory goggles with embedded data sensors that monitor temperature, relative humidity, air flow and blink rate over an hour and a half. A cable carries data saved every 10 seconds to a small box that includes controls and conditioning equipment. A separate hose carries air to the goggles.

The goggles keep the humidity of air around the eyes between 40 and 15 percent -- "about as low as we can go without hurting patients," Alex said.

"We're exacerbating the symptoms so doctors can see them," Hays explained.

Normal patients will produce tears, he said, but those who suffer dry eye will exhibit symptoms, which will give clues about how to treat them. Follow-up sessions with the goggles will let doctors see how well the treatment is working.

"With this, we're putting the power in the hands of clinicians, which is very appealing to them," Shih said.

"We did a lot of research on the ocul
