Electrodiagnostic services can help patients with unexplained vision loss, hereditary eye disorders, and toxicity from certain medications that alter vision.

The machines used can diagnose eye problems that are not able to be diagnosed with other clinical methods.  The Eye Institute houses the only multifocal electroretinogram in the state of Arizona. The Midwestern University Eye Institute houses the latest technology and equipment to serve all patients, from simple cases to complex. The equipment available for referring doctors includes a full- eld electroretinogram (ERG), a multifocal electroretinogram (mfERG), a VEP, an EOG, and a PERG for patient testing. Our mfERG is the only one in the Phoenix Valley and is a powerful tool for assessing the health of foveal cones. We also have a kinetic field machine (Octopus), a high definition OCT, and several color vision tests (D-15, 100 hue).
