pattern electroretinography (PERG)

Adding electroretinography: Technology to clinical utilityPattern electroretinography (PERG) and visually evoked potential (VEP) tests can objectively evaluate the function of axion and retinal ganglion cells. These test results can add another component in successfully treating patients with cataract and/or glaucoma.
How pattern, flicker ERG can impact cataract treatment decisionsRetinal issues can impact cataract surgery outcomes, especially for those with multifocal or other premium lenses. While multifocal lenses may allow the patient to see more clearly across a range of distances, they may also decrease the amount of light that reaches the retina, exacerbating any issues that may already be present.
VEP, ERG testing brings objective data to clinical practiceRecent technologic advances have helped move visual electrophysiological testing into the clinical setting.
