As with all aspects of the neurological examination, important clues come from a thorough and appropriate history. In relation to eye movement disorders the patients may be complaining of double vision, in which case they should be asked whether it is constant or intermittent; does it occur, or is it maximal, in certain directions of gaze; what is the relationship of one image with the other; and have they tried covering one eye and did that relieve the symptom? A less frequently reported symptom is oscillopsia, an illusion of movement of stationary objects, when enquiries need to be made whether the movement is horizontal or vertical, and does it become maximally apparent in certain positions of gaze, as for example in downbeat nystagmus when the oscillopsia is maximal on down gaze. Nystagmus will not be described here and has been covered in a previous article in Practical Neurology.1
