Stimulators, Photic, Visual

Definition : Photic stimulators designed to apply light (i.e., photo) stimuli to the patient's eyes. These stimulators typically consist of a light source that delivers the stimuli (e.g., shifting patterns); the stimuli may be transmitted through an optical system (optical stimulators) or viewed directly from an illuminated screen (direct-view stimulators). Visual photic stimulators are available as independent units or as components of several types of devices, such as refractors, scanning ophthalmoscopes, visual-evoked potential recorders, and electroretinographs.
