Konan Medical launches EvokeDx

December 5, 2014

Konan Medical recently launched EvokeDx, the next-generation visual pathway diagnostics platform to assess visual evoked potentials (VEP) and electroretinograms (ERG).

Irvine, CA-Konan Medical recently launched EvokeDx, the next-generation visual pathway diagnostics platform to assess visual evoked potentials (VEP) and electroretinograms (ERG).

VEPs are visually elicited electrophysiological signals recorded near the brain’s visual cortex. EvokeDx provides highly quantitative, objective measures of visual function. ERG signals are used to differentially assess retina-specific dysfunction, reflecting the integrity of the eye’s optics, photoreceptors, bipolar cells and retinal ganglion cells, providing a limited assessment of the visual pathway.

icVEP is the patented, isolated-check stimulus and analysis strategy that was the subject of an NIH-sponsored, multi-center clinical trial at four U.S. sites and two international locations to rapidly and objectively assess glaucomatous damage.

“In the NIH-sponsored trials, our icVEP strategy had a classification accuracy of 89 to 94 percent,” said Vance Zemon, PhD, a professor at Yeshiva University, Albert Einstein College of Medicine Campus and co-inventor of EvokeDx. A glaucoma diagnostic indication based upon these data was recently granted for the icVEP strategy in China. EvokeDx is FDA 510(k) cleared and the CE Mark is anticipated in the first half of 2015 (an application for glaucoma diagnostic indication has not yet been submitted to FDA for review).

EvokeDx features include patented test strategies that are designed to isolate and test various visual pathways and visual functions, with Fourier-transform frequency analysis methods, and an all-in-one design incorporating a organic LED stimulus display and an automated gaze tracking system that helps ensure patients are fixated correctly during the procedure. Synchronized data collection combined with analysis of the entire EEG waveform provides detailed information about visual pathway function.
