DENVER – Topcon introduced its DRI OCT Triton instrument here at Optometry’s Meeting.

The Triton combines swept source OCT (SS-OCT) and eye tracking with multimodal fundus imaging in an all-in-one imaging tool. Practitioners can visualize the retina and vitreous as well as the choroid and sclera, according to company literature.

Topcon’s Bob Gibson explained to Primary Care Optometry News that SS-OCT has a number of benefits over spectral domain OCT, including en face viewing, an increase in speed and a 1,050-nm wavelength light source that results in clear and detailed images.

Gibson said the instrument, which includes a normative database, performs 100,000 A scans per second and takes half a second per eye to obtain an image. Ganglion cell with inner plexiform layer analysis, ganglion cell with inner plexiform with retinal nerve fiber analysis and retinal nerve fiber layer imaging of the retina is accomplished in one scan, he said.

The Triton can also image through most cataracts and is “great for myopes,” Gibson added.

“It’s very comfortable for the patient,” he said. “The patient doesn’t see anything.”

This technology has been available outside of the U.S. for over 3 years, Gibson said, and OCT angiography is also available outside of the U.S.

“In optometry, doctors are used to SD-OCT and want to get the next generation,” he told PCON. “More clinical practices tend to be interested.” – by Nancy Hemphill, ELS, FAAO.
