Parinaud's syndrome is a constellation of neurological signs indicating injury to the dorsal midbrain. More specifically, compression of the vertical gaze center at the rostral interstitial nucleus of medial longitudinal fasciculus (riMLF).

It is a group of abnormalities of eye movement and pupil dysfunction and is named for Henri Parinaud^[6]^[7] (1844–1905), considered to be the father of French ophthalmology.
