New software reduces OCT measurement variability

June 1, 2003

San Francisco-The newest version (A2) of the Carl Zeiss Meditec software algorithm for quantification of retinal nerve fiber layer (RNFL) thickness using the third-generation optical coherence tomography (OCT 3) showed no improvement in glaucoma discriminating power compared with its predecessor software (A1), but it did reduce the variability of RNFL thickness measurements, according to a Tufts University glaucoma specialist.
