 Visual field testing is widely used to monitor pathologies affecting the periphery of vision such as glaucoma.During a conventional test, patients are asked to look steady (fixate) at a visual target, while light stimuli are projected at varying intensities in different retinal locations.This process is not, however, considered accurate in the evaluation of pathologies affecting the central part of the retina (macula and fovea centralis) patients with these pathologies are often unable to fixate reliably.
