垂直眼振，Oscillopsiaを伴なった視床症候群の2症例

THALAMIC SYNDROME ASSOCIATED WITH VERTICAL NYSTAGMUS AND OSCILLOPSIA REPORT OF TWO CASES

Ｉ．はじめに

　視床は，脳血管性障害の好発部位であるが，Dejerine，Roussy1）によつて記載されたような視床症候群を呈することは稀である。われわれは，古典的視床症候群に垂直眼振，oscillopsiaを伴なつた2症例を経験したので報告する。

Two cases of thalamic syndrome associated with vertical nystagmus and oscillopsia, caused by cere-brovascular disease, were reported. These two cases showed the "classical" thalamic syndrome described by J. Dejerine and G. Roussy. Although these two cases were not associated with internuclear ophthal-moplegia, hemiplegia alternans and dissociated sen-sory impairment ; diplopia was noted. Therefore, association of the brain stem lesion is considered in these two cases.
