What do VEPs primarily monitor?

Visual evoked potentials (VEPs) are primarily used to monitor the visual pathway from the retina through the optic nerve to the visual cortex. By analyzing the electrical activity produced in response to visual stimuli, VEPs can assess the integrity and functionality of this pathway, making them a useful diagnostic tool for a variety of visual system disorders.

Other options, while related to vision, do not focus on the monitoring of the visual pathway itself. Visual acuity pertains to the clarity or sharpness of vision, which can be affected by many factors but does not directly measure the neural transmission involved in visual processing. Retinal health concerns the state of the retina itself, including any potential damage or disease located there, without extending to the neurological processing of visual signals. Similarly, while color perception is an important aspect of vision, measuring it does not provide information on the overall functionality of the visual pathway as a whole.
