Eye movement disorders

The past year's literature on eye movements is characterized by two trends: first by the examination of eye movement organization in the three planes of eye rotation in normal subjects (there is yet no publication about abnormalities of this three-dimensional organization in patients) and second by the increasing awareness of clinicians that the characteristics of saccades are highly task-dependent, and that the saccadic performance of patients must be tested under various conditions. Several papers try to establish a correlation between the site of a lesion and abnormalities of specific parameters of task-dependent saccades. For a better understanding, the different experimental tasks for the elicitation of saccades are explained in the text.
