  They can cause a manifest or latent reduction in visual acuity, torticollis and altered binocular vision. [fundacionmapfre.org]

  Congenital nystagmus is one of the main causes of torticollis [4]. Our purpose is to describe the abnormal head position that can be present in many patients with nystagmus from a clinical and a surgical point of view. [hindawi.com]

  It occurs with a unique triad of symptoms including pendular nystagmus, torticollis, and head nodding. The pendular nystagmus may be horizontal, vertical, torsional, or mixed. [dizzydoctor.com]

  It is often accompanied by head nodding and torticollis. All signs disappear during sleep. It is a benign condition, although space-occupying lesions (especially gliomas of the anterior visual pathway) can present in a similar way. [patient.info]

  In miners the eye movements are very rapid, increase on upward gaze, and are often associated with vertigo, head tremor, and photophobia. [medical-dictionary.thefreedictionary.com]

  There is often a family history of sensory deprivation and examination reveals poor vision, photophobia, abnormal pupillary reactions and optic neuropathy. High refractive error and retinopathy are common findings. [patient.info]

  An ocular examination should be performed with the best age dependant equipment available specifically looking for signs of photophobia, retinal dystrophy, retinal/choroidal hypopigmentation, iris transillumination and anterior segment anomaly e.g., cataract [nature.com]

• Oscillopsia

  Some patients describe oscillopsia (the perception of continual movement of the visual environment). Generally, if a patient is unaware of oscillopsia, the nystagmus is likely to be congenital. [patient.info]

  Symptoms included diplopia and oscillopsia. [collections.lib.utah.edu]

  Base-in prisms alleviated symptoms of oscillopsia at near and improving reading visual acuity. [journals.lww.com]

  Supranuclear disorders can also cause nystagmus or nystagmus-like oscillations, which are unwanted eye movements that can degrade vision or cause oscillopsia. [neurology.mhmedical.com]

  Patients with acquired nystagmus are more likely to experience oscillopsia but the presence or absence of this symptom should not be considered diagnostic. [aop.org.uk]

• Vertigo

  Part IV is a new section on the symptomatic treatment of vertigo. The third edition is thoroughly revised and has been expanded, covering the rapid advances that have occurred in the field in the last ten years. [books.google.de]

  The condition, benign positional vertigo, produces vertigo and nystagmus when the head is moved in certain directions. It can arise spontaneously or after a concussion. Motion sickness medicines sometimes help. [medical-dictionary.thefreedictionary.com]

  This is associated with vertigo, tinnitus and hearing loss. It may be found in acute labyrinthitis, Ménière's disease and benign paroxysmal positional vertigo. Vestibular nystagmus is often sporadic in these conditions. [patient.info]

  A small literature exists about this called "matitutional vertigo". Downbeating nystagmus can be elicited by the head-shaking test. [tchain.com]

• Dizziness

  "Dizziness" is a complaint commonly heard by neurologists, otolaryngologists, and other health care providers, yet its origins are many and often difficult to pinpoint and to treat. [books.google.de]

  The patient may have dizziness (vertigo), nausea and vomiting, and nystagmus. Brain lesions. Disease in many parts of the brain can result in nystagmus. Alcohol and drugs. [medical-dictionary.thefreedictionary.com]

• Hyperactivity

  Downbeat nystagmus is usually caused by lesion of cerebellar flocculus, which in turn resulting in disinhibition of SVN-VTT pathway, followed by relative hyperactivity which drive the upward slow-phase. [teddybrain.wordpress.com]

   Hyperactive after floccular lesions → DBN 81. [slideshare.net]

  The horizontal VOR is hyperactive (1276,1278) or normal (1283) Caloric tests frequently show increased responses, though a few may have absent caloric responses (1275). [neuroophthalmology.ca]

A thorough workup, including neuroimaging is essential to rule out anatomic lesions or other causes of this syndrome. Visually significant upgaze palsy can be relieved with bilateral inferior rectus recessions. [en.wikipedia.org]

Diagnosis, Workup and Treatment Given the patient’s motility deficits with convergence-retraction nystagmus, a lesion in the dorsal midbrain was suspected. [reviewofophthalmology.com]

We discuss the differential diagnosis, suggest a methodical approach to the diagnostic workup, and reveal the final diagnosis. [jamanetwork.com]

The prevalence of IN is estimated at 0.14%. 1 In most cases of IN, a thorough workup will reveal comorbid afferent visual system pathology. 8 Whether or not this can be said to ‘cause’ nystagmus is still a point of disagreement within the literature. [aop.org.uk]

It is necessary for this kind of nystagmus to perform a complete neurological and endocrinological workup. [intechopen.com]

Part III presents differential diagnostic points that help the clinician decide on the cause and treatment of the patient's problem. Part IV is a new section on the symptomatic treatment of vertigo. [books.google.de]

Prognosis[edit] The eye findings of Parinaud's syndrome generally improve slowly over months, especially with resolution of the causative factor; continued resolution after the first 3–6 months of onset is uncommon. [en.wikipedia.org]

The visual prognosis is reasonably good, but if the head turn is excessive, extraocular muscle surgery may be needed. [medical-dictionary.thefreedictionary.com]

Highly variable and depend on the etiology, but the lesion will be affecting the medial midbrain or pons of the brainstem 3,5,8. Treatment and prognosis Highly variable and depend on the etiology 2. Promoted articles (advertising) [radiopaedia.org]

The etiology of abnormal vertical eye movements and convergence nystagmus is discussed with emphasis on the neurotological examinations and MRI. [jstage.jst.go.jp]

However, the most common causes are pineal region tumors, brainstem hemorrhage, and ischemic infarction.[1][4][7] Pineocytoma and germinoma account for up to 40% of all the tumors causing PS.[1][8] The etiology of PS is also correlated with patient age [eyewiki.aao.org]

The most common etiology is a pituitary tumor. Other etiologies include craniopharyngioma, meningioma, aneurysm, glioma, inflammation, MS, and ischemia, as can be seen with lupus or giant cell arteritis. [ajnr.org]
