Evoked Potentials Clinic (Electrodiagnostics)
The Evoked Potentials (EP) / Electrodiagnostics Clinic section of Medical Physics and Clinical Engineering provides a wide range of specialised patient investigations to assist with the diagnosis of disorders affecting hearing, balance and vision. Patients are referred to the clinic from a wide range of directorates and centres, including Ophthalmology, ENT, Nottingham Cochlear Implant Programme (NCIP) and the Nottingham Newborn Hearing Screening Programme (NHSP) and also from other hospitals outside Nottingham. It is in these specific areas that service development and research are mainly directed. An example of the development of an investigation, which now forms part of our diagnostic test battery, is the multi-focal technique for performing electroretinography and visual evoked potential investigations.
Visual investigations
- Electroretinography (ERG) - Flash/Pattern/S-Cone/On-Off
- Electro-oculography (EOG)
- Visual Evoked Potentials (VEP) - Reversal/Onset/Flash
- Multifocal Electroretinography (mfERG)
- Multifocal Visual Evoked Potentials (mfVEP)
Auditory investigations
- Auditory brainstem response (ABR) - threshold/neurological/screening
- Evoked otoacoustic emissions (OAE)
- Electrocochleography (ECochG)
- Auditory cortical response (ACR)
- Cochlear implant related tests (CI)
- Vestibular evoked myogenic potential (VEMP)
