Excerpt

The oculomotor examination begins after examining visual acuity and visual fields. This chapter deals with the examination of five aspects of ocular function: fixation, saccadic movements, pursuit movements, compensatory movements and opticokinetic nystagmus. The monograph by Leigh and Zee (1983) and the book by Miller (1985) are excellent sources of further information.Dysfunction of cranial nerves III, IV, and VI is recognized by identifying the paralysis of individual eye muscles innervated by these nerves. Three methods are commonly used to identify paralysis of the individual eye muscles.
