PVEP,也就是视觉诱发电位,是眼科“三大电生理检查”中,与弱视相关性最强的检查。PVEP是一组二维波形,判断波形好坏,主要看两个方面振幅和潜伏期。 有些轻微弱视眼的PVEP波形是正常的,但多数中重度弱… 阅读全文 VEP BCI: t-VEP, f-VEP, c-VEP
Visual Evoked Potential refers to the averaged response recorded from occipital electrodes in response to visual stimuli, with a main component known as P100 occurring at 100 milliseconds. It is used to assess visual acuity and can help in diagnosing conditions like multiple sclerosis based on abnorm...
visual evoked potential (redirected fromVisual Evoked Potentials) vis·u·al e·voked po·ten·tial voltage fluctuations that may be recorded from the occipital area of the scalp as the result of retinal stimulation by a light flashing at quarter-second intervals; commonly added together and averag...
Visual evoked potentials(VEPs) are used to assess the visual conduction pathways from eye to visual cortex. Many types of visual stimulation may elicit a VEP, but some elicit more reliable responses. A pattern-reversal simulation (e.g., a black and white checkerboard pattern, with black and...
Background and Objectives: Pattern-reversal visual evoked potential (PRVEP) is an objective, sensitive and non-invasive neurophysiological test that can prove to be a useful clinical tool in investigating the physiology and pathophysiology of human visual system. A successful clinical application of the...

To determine if sweep visual evoked potential (VEP) acuity is predictive of recognition acuity in children with albinism. A retrospective review was performed in children with albinism who underwent sweep VEP testing from 1992 to 2003. All patients had a complete ophthalmologic examination with either...
Flash visual evoked potential (FVEP), induced by OFF-to-ON flash, i.e. flash onset, in a light emitting diode (LED) was used to control four cursor movements (left, right, up, down), and left- and right-button clicks on a screen menu. ON or OFF duration in each flashing sequence...
