Two patients with thalamic infarctions presented with vertical gaze palsies. Magnetic resonance imaging (MRI) demonstrated extension of the lesions into the upper midbrain. A common vascular supply to both areas, and the inability of computed tomography (CT) scans to adequately assess posterior fossa structures, necessitate MRI of the mesencephalon in the assessment of all patients with vertical gaze dysfunction. These cases shed further doubt regarding a specific role of the thalamus in control of vertical eye movements.
两名患有丘脑梗死的患者出现垂直凝视麻痹。磁共振成像（MRI）显示病变延伸至中脑上部。这两个区域有共同的血管供应，且计算机断层扫描（CT）无法充分评估后颅窝结构，因此在评估所有垂直凝视功能障碍患者时，需要对中脑进行MRI检查。这些病例进一步质疑了丘脑在控制垂直眼球运动中的特定作用。
