Nowhere to hide: New device sees bacteria behind the eardrum
Date:5/29/2012

rence tomography (OCT), a non-invasive imaging system devised by Boppart's group. It uses beams of light to collect high-resolution, three-dimensional tissue images, scanning through the eardrum to the biofilm behind it much like ultrasound imaging, but using light.

"We send the light into the ear canal, and it scatters and reflects from the tympanic membrane and the biofilm behind it," said graduate student Cac Nguyen, the lead author of the paper. "We measure the reflection, and with the reference light we can get the structure in depth."

The single scan is performed in a fraction of a second speed is a necessity for treating squirming tots and images a few millimeters deep behind the eardrum. Thus, doctors can see not only the presence of a biofilm, but also how thick it is and its position against the eardrum.

The paper marks the first demonstration of using the ear OCT device to detect biofilms in human patients. To test their device, the researchers worked with clinicians at Carle Foundation Hospital in Urbana, Ill., to scan patients with diagnosed chronic ear infections, as well as patients with normal ears. The device identified biofilms in all patients with chronic infections, while none of the normal ears showed evidence of biofilms.

"I think this is now a technology that allows physicians to monitor chronic ear infection, and examine better ways to treat the disease," said Boppart, who is also affiliated with the departments of bioengineering and internal medicine, the Institute for Genomic Biology, and the Beckman Institute for Advanced Science and Technology at the U. of I. "We can use different antibiotics and see how the biofilm responds."

Next, the researchers plan to investigate different ear pathology, particularly comparing acute and chronic infections, and will examine the relationship between biofilms and hearing loss. They hope that improved diagnostics will lead to better treatment and referral
