University of Tennessee Space Institute researchers make clinical trials a virtual reality
Date:8/30/2012

sive to find the diversity and range of subjects. The result is an uncertainty in the performance of new instruments to detect and diagnose a range of unusual eye conditions. In the virtual world, users can manipulate the eye, such as opening it partially or rotating the pupil. They can also give it certain conditions, such as growing a cataract or developing a tear duct issue. This allows users to see how well their instrument measures in response to such conditions.

This characteristic can be especially useful in assisting surgical planning by predicting outcomes of visual performance.

"For instance, we can predict how one person's eye can react to LASIK surgery and simulate the day and night vision after the procedure," said Chen. "Today, it is also not well known on how the long-term outcome of new interventions would be. But in the virtual world, we could induce cataract and dry eye and other aging conditions to predict the possible complicated outcomes and problems."

Eye Bank could also be helpful in medical education, as most students are not trained on diseased eyes.

Although currently used for optical research, the researchers see broad applications for their technology.

The research is currently undergoing testing funded by the National Institutes of Health.
