“…With alteration of position, the receptor organs are probably the vestibular apparatus and receptors in the neck muscles (Joppich andSchulte 1968, Sanders andBird 1970). Downward rotatory movements are mediated by the oculomotor and the trochlear nerves, which innervate the inferior rectus and superior oblique muscles respectively.…”

“…The supranuclear centre for vertical eye-movements is thought to be situated in the tegmentum or in the lamina tecti (Holmes 1921). Stereotaxic neurosurgical techniques in humans have shown that paralysis of upwards or downward gaze, together with retraction of the eyelids, can arise from unilateral lesions in the dien-cephalon or mesencephalon (Nashold The variation in the mechanism of and Gills 1967).…”

SUMMARY In a longitudinal study, 19 infants who displayed the setting‐sun eye phenomenon were observed during the first year of life. Nine of the infants showed no signs of illness, eight had an evident increase in intracranial pressure requiring surgical relief, and two had transient signs of increased intracranial pressure which resolved spontaneously. The setting‐sun phenomenon could be elicited both by alteration of the infant's position and by removal of light, and it also occurred spontaneously. The effectiveness of the eliciting mechanism depended on the age of the infant. The component parts of the phenomenon consist of downward rotation of the eyeballs and retraction of the upper eyelids, sometimes accompanied by raising of the brow. The phenomenon can be observed in healthy infants, and its value in early recognition of increased intracranial pressure is limited. The response might indicate increased intracranial pressure if it can be elicited by alteration of position in infants older than four weeks of age or if there is a marked response to removal of light in infants younger than eight weeks or older than 20 weeks of age, especially if the response is combined with constant or intermittent strabismus or undulating eye‐movements. RÉSUMÉ Le signe du voucher de soleil chez le nourrisson Le signe du coucher de soleil a étéétudié au cours d'une étude longitudinale chez 19 nourrisons ayant présenté ce symptome au cours de la première année de la vie. Neuf enfants ne présentaient aucun symptôme pathologique; il y avait une hypertension intra‐crânienne ayant nécessité une intervention chirurgicale chez huit autres; deux nourrissons avaient présenté des signes transitoires d'hypertension intracrânienne qui avaient évolué spontanément vers la guérison. Le signe du coucher de soleil pouvait être provoqué par la modification de la position du nourrisson et par la diminution de la lumière. Il survenait également spontanément. Le mécanisme déclenchant dépend de l'âge de l'enfant. La principale composante est une rotation vers le bas et une rétraction de la paupière superieure quelque fois associée à une élévation du sourcil. Le symptôme peut être observé chez des enfants en bonne santé. La valeur du signe du coucher de soleil dans le diagnostic précoce de l'hypertension intracrânienne est limitée. Chez des nourrissons de plus de quatre semaines, il peut indiquer une hypertension intracrânienne s'il est produit par une modification de la position; chez les enfants de moins de huit semaines ou de plus de vingt semaines, il a la même valeur s'il est observé après diminution de la lumière, spécialement s'il est associéà un strabisme constant ou intermittent ou encore à des mouvements ondulatoires de l'oeil.

“…According to Bender SC Shanzer, there is clinical and pathological evidence that the decussation occurs somewhere between the superior midbrain and tegmentum of the pons, and experimental evidence that it takes place at the level of the oculomotor and trochlear nuclei ( 1 , 2). As a consequence of the decussation, pontine lesions disturb conjugate movements of the eyes towards the homolateral side (16). The paralysis has a tendency to persist, in contrast to the transient horizontal gaze palsy in cortical lesions.…”

“…) aqueductal stenosis who had paralysis of upward gaze and pupillary abnormalities. Subsequently, there have been isolated case reports of upward gaze paralysis occurring in hydrocephalus, mostly of later onset (Globus and Bergman, 1946;case 1;Beckett et al, 1950, case 8;Cassinari et al, 1963;Nag and Falconer, 1966, case 8;Lerner et al, 1969;Jerva and Nelson, 1971;Shallat et al, 1973;and Swash, 1974); however, this reported association has not found its way into the leading textbooks of neuro-ophthalmology of Kestenbaum (1946), Cogan (1956), and Walsh and Hoyt (1969) and the review articles of Holmes (1921), Smith et al, (1959), Segarra and Ojeman (1961), and Hatcher and Klintworth (1966).…”

Sylvian aqueduct syndrome as a sign of acute obstructive hydrocephalus in children.

SYNOPSIS Eight cases of obstructive hydrocephalus manifesting palsy of upward gaze and other features of the Sylvian aqueduct syndrome are reported. During the crisis of intracranial hypertension, all of them developed upward gaze palsy and variable abnormalities of the convergence mechanism such as paralysis, spasm, and convergence nystagmus. The frequent apparent blindness was probably related to gaze paralysis, since visual evoked responses were present. All these ocular abnormalities disappeared after shunting. Periaqueductal dysfunction on the basis of raised intracranial pressure is postulated as the possible mechanism for the above ocular manifestations. The ' setting sun' sign is frequently seen in infants and children with hydrocephalus and has been considered in the past to result from displacement of eyeballs by pressure from the orbital roof plate. Our observations would suggest periaqueductal dysfunction rather than the mechanical displacement as the possible mechanism for this sign.
