 Perimetry is a well-established method that is used to measure the visual field functions of humans. Commercially available products, such as the OCTOPUS 900 Haag-Streit AG, Koeniz, Switzerland, are commonly used for assessing the visual field. Such devices are of critical value for patients suffering of glaucoma and neuro-ophthalmic conditions. The operating principle is to sequentially present light stimuli of different intensity at different locations within the visual field in an automatic way. Algorithms that select what locations and intensities to present over time are called strategies. These have the goal to provide both a fast and accurate estimation of the visual field function.
