[Raeder's paratrigeminal syndrome].

Two clinical observations of Raeder's paratrigeminal syndrome were described: an isolated form elicited by dissecting aneurysm of internal carotid artery and a combined form caused by intracavernous aneurysm of internal carotid. An analysis of published and the author's cases enabled determination of topical varieties of Raeder's syndrome. Miosis in Raeder's syndrome is of two types according to retained or disappeared pupilloconstriction reactions. In intracranial topical varieties--intracavernous, retrocavernous and supracavernous--the Raeder's syndrome is mostly of combined character, in extracranial lesions of internal carotid it is isolated or combined.
