The tests offered in this clinic include the:
- Electroretinogram (ERG)
- Electro-Oculogram (EOG)
- Visually Evoked Potential (VEP)
The ERG, EOG and VEP are specialized tests of specific parts of the visual system. Sight depends on the generation of naturally occurring electrical activity in the eyes and the transmission of these signals to the brain. These tests record this electrical activity either from the eye or from the vision centre of the brain. This is done by the use of recording sensors which rest on the scalp or near the eye. These tests can be useful in the diagnosis of certain diseases of the visual system. The test protocols followed are consistent with standards set by the International Society for Clinical Electrophysiology of Vision (ISCEV).
