Visual field loss
Perimetry has always had a central role in the investigation of 'afferent' diseases in neuro-ophthalmology. In this workshop we will concentrate on the following aspects of this dark art:
- When should you test the peripheral vision? Although the need for perimetry is usually obvious, we will discuss some situations in which perimetry may not be a 'first line investigation' but can be very helpful
- What technique should we choose to measure the visual fields? We will consider a wide range of options from lo-tech/bedside assessments to hi-tech solutions using fixed equipment, and discuss what considerations to take into account when deciding on the best approach for each individual patient
- How do we interpret the results? We will summarise the patterns of visual field loss associated with lesions at different locations within the visual system, and consider the false positives, false negatives and other bear traps of perimetry in clinical practice!

He then did a clinical fellowship in neuro-ophthalmology at the National Hospital for Neurology & Neurosurgery, Queen Square London where he now works as a consultant. He has a particular interest in disorders of the pupil and the use of OCT imaging in neuro-ophthalmology.
