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.
Symptoms typically begin in early adulthood, with back pain, stiffness in the lower back, neck pain, and fatigue being common ones. Steff received an official diagnosis of ankylosing spondylitis ...
Parinaud's syndrome, which can mimic some aspects of spasm of the near reflex, such as excessive accommodation and convergence; however, pupillary near-light dissociation, not miosis, is a feature of Parinaud's syndrome. [8]
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 .
[9] [10] This occurs ~2 1/2 months following injury, without associated neurological symptoms or pain, and typically resolves within 1 year. [ citation needed ] This sign is also sometimes seen as part of a " discontinuation syndrome " associated with certain psychotropic medications, such as selective serotonin reuptake inhibitors and ...
Patients typically present with pain associated with visual loss. [1] CRION is a clinical diagnosis of exclusion , and other demyelinating, autoimmune, and systemic causes should be ruled out. [ 3 ] An accurate antibody test which became available commercially in 2017 has allowed most patients previously diagnosed with CRION to be re-identified ...
