Physical exam is notable for an upward gaze palsy and a pupillary light-near dissociation. Br J Ophthalmol. Parinaud syndrome due to metastatic lesion of the pineal gland has been reported rarely in the literature. g. Parinaud’s syndrome or dorsal mid brain syndrome was first described by Henri Parinaud in 1983 [1] with vertical paralysis and/or convergence paralysis and includes a putative case of multiple sclerosis. Miller Fisher syndrome was described as a triad of total external ophthalmoplegia, ataxia and loss of tendon reflexes. Argyll Robertson pupil is a highly specific sign of neurosyphilis that is defined by the emergence of bilateral pupils, which are small and show a poorly constructive response to light beside a light-near dissociation. It took nearly a century of determined effort to reveal that Henri Parinaud’s oculoglandular syndrome (POGS) (1889) and Leber’s stellate retinitis (1916) were the result of B. Parinaud's Syndrome, also known as dorsal midbrain syndrome, vertical gaze palsy, and Sunset Sign, is an inability to move the eyes up. The most common causes of this syndrome are acute hydrocephalus, brainstem. Downward gaze preference or tonic downward deviation of the eyes ("setting-sun sign") Primary position upbeat or downbeat nystagmus Impaired convergence and divergence. This benign phenomenon is believed to be caused by immaturity of reflexes controlling eye movements. First-order neuron: fibers from Edinger-Westphal nucleus → oculomotor nerve fibers (located in the periphery of the oculomotor nerve) → ciliary ganglion. It is also known as Sylvian aqueduct syndrome, pretectal syndrome, and dorsal midbrain syndrome.
