pERG


Also found in: Acronyms, Wikipedia.

pERG

indicates that this potential is pattern-elicited. The ERG and pERG are useful indicators of the health of all the layers of the retina and can differentiate between the functioning of the rods and cones. See alternating checkerboard stimulus; Leber's congenital amaurosis; early receptor potential; oscillatory potentials; retinitis pigmentosa.

The PERG test parameters were in accordance with the ISCEV standard [16].
