Overview
The Visual Electrophysiology team support our Consultant colleagues in the diagnosis and monitoring of various diseases which affect the retinae, optic nerves and visual cortex. We do this by using electrodes to record the tiny electrical signals produced by the eyes and brain while our patients view alternating patterns or flashes of light. Our tests are painless and non-invasive, and provide information about how well the retinae and visual pathways are functioning. This functional information can be used alongside other diagnostic tests such as retinal imaging, visual field testing and MRI to build a complete picture of both the structure and function of a patient’s visual system.
Our clinics run at the Royal Hallamshire Hospital for testing of adults, and at the Sheffield Children’s hospital for testing of under 16s.

Clinic
Adults (aged 16 and over) are seen at the Royal Hallamshire Hospital Electrodiagnostic Suite. This is in the Ophthalmology Out-Patients Department on A floor.
Children (under 16’s) are seen at the Sheffield Children’s Hospital Electrodiagnostic Suite. This is in Zone 2 of the Ophthalmology Out-Patients Department on the ground floor.

A facility for performing ISCEV standard Electroretinography (ERG) in theatre under general anaesthesia is available at the Sheffield Children’s Hospital. This requires referral to an SCH consultant ophthalmologist.
Referrers
We accept referrals from Ophthalmic and Neuro consultants. Our referral forms ensure that we receive all the required details to make an informed test plan tailored to each patient:
