Glaucomatous Patterns in Frequency Doubling Technology (FDT) Perimetry Data Identified by Unsupervised Machine Learning Classifiers
Figure 3
Color-coded displays simulating total deviation plots along with age at −2 and +2 standard deviations of each axis from the centroid of Cluster N, that was composed primarily of normal FDT fields.
Axis 1 and Axis 2 appear normal or near normal. Numerical values shown are simulated total deviation values at each corresponding test point.
