Presentation
The need for neuroimaging and electroretinography (ERG) has been widely debated, especially because clinical presentation and eye and head movement recordings are not satisfactory for predicting whether underlying conditions may be present (3). [journals.lww.com]

- Nystagmus
Disease Entity Disease Spasmus nutans syndrome is an acquired form of nystagmus that occurs in children typically within the first two years of life. It presents as a clinical triad of 1) nystagmus 2) head bobbing 3) torticollis. [eyewiki.aao.org]
RESULTS We identified 22 patients with SN-like nystagmus (Table 1). Twelve (55%) were male and 10 were female (45%). Eight (36%) patients had monocular nystagmus and 14 patients (64%) had binocular disconjugate nystagmus. [journals.lww.com]

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

If the symptoms are caused by another condition, the provider will recommend appropriate treatment. Usually, this disorder goes away on its own without treatment. [medlineplus.gov]
Prognosis
Spasmus nutans carries an excellent prognosis with 20/50 vision or better in most. A higher incidence of strabismus and amblyopia is associated in followed cases compared to controls. [shmabstracts.org]
Prognosis The prognosis for spasmus nutans is very good. Long term follow up studies have shown that good visual acuity can be expected in patients with spasmus nutans. [eyewiki.aao.org]
