Parinaud's syndrome is a cluster of abnormalities of eye movement and pupil dysfunction, characterized by: Paralysis of upwards gaze: Downward gaze is usually preserved. This vertical palsy is supranuclear , so doll's head maneuver should elevate the eyes, but eventually all upward gaze mechanisms fail.
Frequently, paralysis of upward gaze along with several ocular findings such as convergence retraction nystagmus and eyelid retraction also known as Collier's sign and Light Near Dissociation (pupil accommodates but doesn't react to light) are known collectively as Parinaud's syndrome [1] or Dorsal Mid-brain syndrome, are the only physical ...

A third cause of light-near dissociation is Parinaud syndrome, also called dorsal midbrain syndrome. This uncommon syndrome involves vertical gaze palsy associated with pupils that “accommodate but do not react." [5] The causes of Parinaud syndrome include brain tumors (pinealomas), multiple sclerosis and brainstem infarction.
Dorsal midbrain structures, as in Parinaud's syndrome. Certain parts of the cerebral cortex (including the frontal eye fields), as in stroke. Toxic envenomation by mambas, taipans, and kraits. Thiamine deficiency can cause ophthalmoparesis in susceptible persons; this is part of the syndrome called Wernicke encephalopathy. The causal pathway by ...
When Melania landed at the Helsinki Airport in Finland, all eyes were feet which bore a pair of flats (yes, flats) from the French brand. The former model wore the brand's 'Solasofia' flat , which ...
Though the woman reports that she is only 151cm, or 4' 11", tall, an image in her blog post shows one of her lengthy metatarsals clocking in at an impressive 5cm, or 2in.
Parinaud's oculoglandular syndrome (POS) is a medical condition characterized by a specific set of symptoms affecting the eye and nearby lymph nodes. Named after the French ophthalmologist Henri Parinaud , it should not be confused with the neurological syndrome caused by a lesion in the midbrain which is also known as Parinaud's syndrome .
