Retinal Function Testing for Vision Abnormalities

The provider performs an electrophysiologic test of retinal function, which consists of multifocal electroretinography (mfERG) to detect localized retinal abnormalities or cone–rod dysfunction. The retina of the eye is responsible for visual image formation, and the rods and cones are involved in dark adaptation and color vision. Choose a location to see hospital-reported price summaries.
