UPMC’s electrophysiology and psychophysics service utilizes a variety of sophisticated technologies and methods to detect, diagnose and evaluate various visual disorders. The visual electrophysiology tests are objective and non-invasive and are compiled using ISCEV standards. The tests assess visual functions along the visual pathway from the retina to the primary visual cortex. The services are provided to both children and adults. The following tests are available:
Visual Evoked Potentials are used to assess integrity and maturation of the visual systems. VEP can be used to determine the visual potential and visual acuities of infants and non-verbal adults, evaluate neurological diseases such as multiple sclerosis, optic neuritis, amblyopia, cortical blindness. Our service provides the following tests:
An electrooculogram evaluates the function of the outer retina and retinal pigment epithelium. It is useful in assessing the Best's vitelliform macular dystrophy, Stargardt’s disease or fundus flavimaculatus, and dominant drusen.
Teller Acuity Cards are used to determine pediatric visual acuity. This test can be used for infants or pre-veral children vision screening which is crucial to health visual development.
Most insurances accepted for the above tests. Please call 412-647-2200 or 1-800-446-3797 to schedule an appointment.
