From: Using eye movements to detect visual field loss: a pragmatic assessment using simulated scotoma

IVFs and example screenshots from the three simulated-VF loss conditions: (a) no VF loss. (b) moderate VF loss. (c) advanced VF loss. The impairments were constructed on monocular field data from a single real patient. The IVF was estimated by taking the maximum sensitivity from corresponding points in the left- and right-eye VFs. Note that the simulated VF loss moved depending upon the observer’s current point of gaze (white cross), and so remainined approximately static in retinal coordinates.
