A 79-year-old woman who developed bilateral paramedian midbrain-thalamic infarction manifested complete bilateral ophthalmoplegia resistant to caloric stimulation, indicating impairment of the vestibulo-ocular reflex (VOR). Previous reports have mentioned this phenomenon but have not explicitly reported the results of caloric testing. Why a lesion apparently confined to the upper brainstem should produce impairment of the horizontal VOR remains unexplained.
一位 79 岁女性出现双侧旁正中中脑-丘脑梗死，表现为双侧眼外肌完全瘫痪，对冷热刺激无反应，表明前庭眼反射（VOR）受损。先前的报告提到了这种现象，但没有明确报告冷热测试的结果。为什么明显局限于脑干上部的病变会导致水平 VOR 受损仍未得到解释。
