title: [Convergence nystagmus: an oculographic analysis].
abstract: Convergence nystagmus and nystagmus retractorius represent important ocular motor disorders in cases of periaqueductal involvement and serve as valuable topographical clue in the Sylvian aqueduct syndrome. The oculographic tracings of a 34-year-old male suffering from a pinealoma are presented. It is outlined, under which circumstances convergence nystagmus is elicited, and the typical features of this disconjunctive nystagmus are discussed.
