Comparison between Tendency-Oriented Perimetry (TOP) and octopus threshold perimetry.

Abstract

To compare the results obtained by a new ultra-short automated perimetry test known as Tendency-Oriented Perimetry (TOP), which is an algorithm based on estimation of thresholds from information gathered from adjacent points with those obtained by a standard bracketing approach. TOP is designed to save up to 1/5 of the time taken by standard strategy by presenting each stimulus once on each location (instead of 4 to 6 times per location with the standard technique) and reaching a final threshold estimate by gathering information from responses to adjacent locations.
