    Honors celebrate research, future generation in retina



    Ms. Arya, OCT research fellow, New England Eye Center at Tufts University, Boston, assessed the variability in vessel density measurements across three OCTA devices (Optovue RTVue, Zeiss Cirrus, and Zeiss Plex Elite 9000) to identify a method that offers the least amount of variation in vessel density.  She found a statistically significant variability existed among the devices for a single normal imaged patient.

    The vessel area density values varied less than vessel skeleton density (VSD) values.

    “After registration of multiple repeats, mean VSD was significantly different than that of unregistered scans on each device,” she said. “However, numerically, the differences noted were small with mean VSD remaining within 1% of a single volumetric scan, for which clinical significance remains to be determined.”
