Neurological Disorders





Neurological Disorders is the third in our series of lecture-style CD-ROMs.  This final lecture is designed to update and refresh knowledge of aspects of neurology relevant to optometric practice, including Visual Field abnormalities, Pupil anomalies, Oculomotor anomalies and headache.

The first level objectives of the programme are to:
  • give a clear instruction in the signs and symptoms associated with each clinical area (e.g. papilloedema, diplopia etc.)
  • provide an outline of relevant clinical investigations
  • provide guidance on differential diagnosis
  • provide information to enable the correct management of such patients in community pratice
The lecture is given by Fion Bremner, a Consultant at the National Hospital for Neurology and Neurosurgery in London.
