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). As surgical biopsy can have significant morbidity in this area, usually the diagnosis is made on imaging findings alone. Parinaud oculoglandular syndrome is a conjunctival disease characterized by a unilateral granulomatous follicular conjunctivitis associated with ipsilateral regional lymphadenopathy. - Collier's tucked lid sign or posterior fossa stare (Bilateral or unilateral eyelid retraction) Seen in: - Germ cell tumors (Most common cause of. It consists of an up-gaze paresis with the eyes appearing driven. Clinical signs include limitation of upward gaze, light-near dissociation of the pupillary response, eyelid retraction (Collier's sign) and convergence-retraction. The video demonstrates the classical triad of Parinaud syndrome including vertical gaze palsy, light-near dissociation, and convergence-retraction nystagmus.
