Shields M, Sinkar S, Chan W, Crompton J. Clinical signs include limitation of upward gaze, light-near dissociation of the pupillary response, eyelid retraction (Collier's sign) and convergence-retraction. D. They may also cause paresis of upward gaze and loss of pupillary light and accommodation reflexes by compressing the pretectum rostral to the superior colliculi (Parinaud syndrome. Parinaud’s syndrome, also referred as pretectal syndrome, dorsal midbrain syndrome, Sunset Sign, and vertical gaze palsy, is a group of abnormalities of pupil dysfunction and eye movement. Myasthenia gravis and Guillain-Barré syndrome also may simulate INO. (When someone has a primary downward gaze, it is referred to as the setting-sun sign or sunset eyes ).

Neurosurgeons see this sign most commonly in patients with hydrocephalus. More specifically, compression of the vertical gaze center at the rostral interstitial nucleus of medial longitudinal fasciculus (riMLF). Stroke is the most common. 9 The difference in outcome in that case vs Mr. The main manifestations of Parinaud’s syndrome are upward gaze palsy, lid retraction (Collier’s sign), convergence retraction nystagmus (CRN), and pupillary light-near-dissociation [3,5].

This finding is due to the loss of inhibitory convergence pathways and an increase in convergence tone. Compression of the tectal plate may cause an upward gaze palsy (Parinaud syndrome). The classical triad of this syndrome consists of 1) paralysis of conjugate up gaze, 2) light-near dissociation of the pupils and 3) convergence-retraction nystagmus during. This may result in elevation of the corpus callosum, stretching or perforation of the septum pellucidum, thinning of the cerebral mantle, or enlargement of the third ventricle downward into the pituitary fossa (which may cause pituitary dysfunction) as well as dorsal midbrain compression resulting in Parinaud's syndrome (aralysis of upgaze.

Dorsal midbrain syndrome, vertical gaze palsy, upward gaze palzy, sunset sign, [1] setting-sun sign, [2] sun-setting sign, [3] sunsetting. Note: Parinaud syndrome (also called upgaze paresis) is a different disorder in which you have trouble looking upward. Due to their expansive growth within the pineal region, pineocytomas cause signs and symptoms that are related to increased intracranial pressure, because of aqueductal obstruction, brain stem or cerebellar dysfunction, and Parinaud syndrome, which involves neuro-ophthalmological dysfunction. g. The syndrome is characterized by the following: (1) paralysis of conjugate up gaze, (2) light-near dissociation of the pupils, and (3) convergence-retraction nystagmus. , the ‘setting sun’ sign). Of these patients, 13% harbor ventriculoperitoneal shunts that have failed. upward gaze palsy, often manifesting as diplopia pupillary light-near dissociation (pupils respond to near stimuli, but not light) convergence-retraction. Post Assessment Questions. Dorsal midbrain syndrome, also known as Parinaud syndrome—after Henri Parinaud (1844–1905), the French ophthalmologist—may have the following features: (1) vertical gaze palsy, (2) convergence-retraction nystagmus, (3) pupil light–near dissociation and (4) eyelid retraction (Collier’s sign). As noted previously, posterior commissure lesions typically lead to limitations of upward gaze and may be associated with a downward gaze preference (i. Downward gaze preference or tonic downward deviation of the eyes ("setting-sun sign") Primary position upbeat or downbeat nystagmus Impaired convergence and divergence. It consists of an up-gaze paresis with the eyes appearing driven downward. We present a case of Parinaud syndrome with solitary pineal.
