[Clinical patterns of Parinaud's syndrome (author's transl)].

In agreement with other clinical reports we observed in 20 patients that Parinaud's syndrome may be associated with other midbrain symptoms. Most frequently we found convergence insufficiency or pupillary changes. In contrast to textbooks in most cases that was an incomplete, absolute paralysis of pupillary constriction. Some patients had also paresis of the 3rd and 4th cranial nerve or lesions of the medial longitudinal fasciculus (internuclear ophthalmoplegia). All clinical patterns which we noted were understandable in view of the topographical relationship of their presumed lesions. However, none of the symptoms was invariably associated with Parinaud's syndrome.
