Visual Evoked Potential (VEP)
Visual Evoked Potential (VEP) measures the electrical response of the visual pathway, assessing signal transmission from the retina through the optic nerve to the visual cortex.
The Diopsys NOVA VEP test evaluates the strength and timing of these signals, providing objective information on the functional integrity of the entire visual pathway. This helps clinicians assess how effectively visual information is transmitted from the eye to the brain.
Pattern Electroretinography (ERG)
Pattern Electroretinography (pERG) assesses retinal function, particularly the activity of retinal ganglion cells responsible for transmitting visual signals.
The Diopsys NOVA ERG test records electrical responses generated within the retina in response to patterned visual stimuli. These measurements provide objective data on retinal function and can support the diagnosis and management of various retinal and optic nerve-related conditions.
