Randy Atkins: In glaucoma, a blockage of inner eye fluids causes pressure on the retina and optic nerve.  Tingrui Pan, a University of California biomedical engineer, hopes to detect this using a flexible contact lens embedded with tiny particles that conduct electricity.

Tingrui Pan: Once this soft lens is influenced by the pressure fluctuation on the cornea surface, it would deform and send a different electrical signal.

Randy Atkins: Pan says the lenses, still in the lab testing stage, may allow early diagnosis and help patients gauge response to medication.

Tingrui Pan: They will know how this drug will help them to improve their glaucoma condition.

Randy Atkins: Pan says the lenses would be disposable, and need only be worn a few minutes each day for effective monitoring.  With the National Academy of Engineering, Randy Atkins, 103 point 5 F-M, WTOP Radio.
