     Johann Panthakey and Will Ayliffe
    New systems of assessing electrophysiology, such as electroretinography (ERG) and visual evoked potential (VEP) assessments, have been developed in the US, and are being viewed with increasing interest by optometrists. Early results suggest they are easy to use; for example an ERG is now possible with the application of one simple strip electrode under the patient’s lower lid.  And they are able to detect early disease damage, such as ganglion cell loss in early glaucoma. They are also being trialled as a way of assessing macular health - for example while a patient is taking a potentially maculopathic drug such as hydroxychloroquine. Our interviewer, Johann Panthakey talks to consultant ophthalmologist Will Ayliffe who is involved in UK based trials looking at the technique.
