Parinaud syndrome, also known as dorsal midbrain syndrome, is a supranuclear vertical gaze disturbance caused by compression of the superior tectal plate.
Parinaud syndrome is characterized by a classic triad of findings:
upward gaze palsy, often manifesting as diplopia
pupillary light-near dissociation (pupils respond to near stimuli, but not light)
convergence-retraction nystagmus
Its importance lies in that recognition of Parinaud syndrome localizes pathology to impingement of (or origin in) the tectal plate, most frequently due to a posterior commissure or pineal region mass (typically solid tumors rather than pineal cysts).
History and etymology
Named after Henry Parinaud, a French ophthalmologist (1844-1905).
