• Pleural Effusion

  There can be pleural effusions and lobar infiltrates (1257). Neuroimaging including MRI is often normal (1251,1253,1258) but sometimes shows multifocal enhancing lesions (1248,1257). [neuroophthalmology.ca]

• Torticollis

  If vertical torticollis is present, the vertical rectus muscles can also be recessed. Asymptomatic eye movements do not require treatment. [aao.org]

  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]

• Low Self-Esteem

  The authors found that the physical appearance of nystagmus causes individuals to suffer from low self-esteem. The constant oscillation of the eyes and AHP made participants feel that they stand out and/or do not fit in with their peers. [dovepress.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]

  Common causes are lesions of the cerebellum or the vestibular apparatus, or increased intracranial pressure. aural nystagmus labyrinthine nystagmus. cerebellar nystagmus one characterized by tremor, without fast and slow components. [medical-dictionary.thefreedictionary.com]

  There are two variants of palatal myoclonus or tremor (1217). Essential palatal tremor presents with ear clicking from motion of the tensor veli palatini. There is no nystagmus or tremor of other muscles. [neuroophthalmology.ca]

• Upbeat Nystagmus

  Neurology, 60,2003, 344 Central nystagmus (downbeat, upbeat nystagmus, horizontal, torsional) Upbeat nystagmus (UBN). [tchain.com]

  Toxic exposure is infrequent: gaze-evoked upbeat nystagmus is more common than primary position upbeat nystagmus with drug toxicity (1351). [neuroophthalmology.ca]

  Upbeat nystagmus: Upbeat nystagmus is defined as an eye movement pattern in which the slow phase is downwards and the rapid phase is upwards. [dizzydoctor.com]

  Thus any lesion that disturbed this pathway could result in upbeat nystagmus. In addition, similar nystagmus is produced from lesion of caudal medulla. [teddybrain.wordpress.com]

  (G) A burst of saccades without an intersaccadic interval (ocular flutter), typically at a frequency of 10–15 cycles per second. [jnnp.bmj.com]

  Eye movement tics and voluntary nystagmus in older children has been confused with ocular flutter. [nature.com]

  Flutter and Opsoclonus Ocular flutter and opsoclonus can produce oscillopsia. [webeye.ophth.uiowa.edu]

  Differential diagnosis Nystagmus should be distinguished from inappropriate saccades that prevent steady fixation (eg, ocular flutter). [patient.info]

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]

• Pleural Effusion

  There can be pleural effusions and lobar infiltrates (1257). Neuroimaging including MRI is often normal (1251,1253,1258) but sometimes shows multifocal enhancing lesions (1248,1257). [neuroophthalmology.ca]

Abstract Retraction-convergence nystagmus is a classic finding in extensive and bilateral lesions of the dorsal midbrain, usually neoplastic and, as such, considered to signal a poor prognosis. [ncbi.nlm.nih.gov]

Treatment and prognosis Highly variable and depend on the etiology 2. Promoted articles (advertising) [radiopaedia.org]

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]
