In some of these cases the ocular signs proved to be an early and reliable indicator of increased intraventricular pressure due to shunt malfunction. Its importance lies in that recognition of Parinaud syndrome localises pathology to impingement of (or origin in) the tectal plate, most frequently due to a posterior commissure or pineal region mass (typically solid tumours rather than pineal cysts).
