it causes vertical gaze palsy due to pressure on superior colliculi of pons and also I think it can disturb circardian rhythm but not sure from the latter

Correct Answer

Parinaud's Syndrome is a cluster of abnormalities of eye movement and pupil dysfunction, characterized by:
  1. Paralysis of upgaze: Downward gaze is usually preserved. This vertical palsy is supranuclear, so doll's head maneuver should elevate the eyes, but eventually all upward gaze mechanisms fail.
  2. Pseudo-Argyll Robertson pupils: Accommodative paresis ensues, and pupils become mid-dilated and show light-near dissociation.
  3. Convergence-Retraction nystagmus: Attempts at upward gaze often produce this phenomenon. On fast up-gaze, the eyes pull in and the globes retract. The easiest way to bring out this reaction is to ask the patient to follow down-going stripes on an optokinetic drum.
  4. Eyelid retraction (Collier's sign)
  5. Conjugate down gaze in the primary position: "setting-sun sign". Neurosurgeons will often see this sign most commonly in patients with failed ventriculoperitoneal shunts.
