Description
This is a 50-yo-man who suffered a dorsal midbrain stroke. Exam demonstrated normal vertical range of eye movements, normal vertical VOR and smooth pursuit, but inability to perform upward saccades. Another feature of Parinaud's syndrome seen on his exam was light-near dissociation (not shown in this video where he was pharmacologically dilated). Occasionally, a dorsal midbrain syndrome can affect upward saccades with relative sparing of other vertical eye movements, and the patient may have a normal range of vertical movements.
