MeSH Bruns' nystagmus reflects a combination of a vestibular tone imbalance, producing a SN in straight-ahead gaze and a direction-changing GEN.

Bruns nystagmus: an important clinical clue for cerebellopontine angle tumours. Brun's nystagmus localizes to the cerebellopontine angle (CPA) and is most commonly indicative of a mass lesion though stroke has also been reported. With large tumours having maximal diameter greater than 3.5cm, the prevalence was observed to be higher (92% of patients had nystagmus, 67% of whom had Bruns nystagmus).2 It comprisesof a coarse, high-amplitude horizontal nystagmus with low oscillatory frequency as the patient looks towards the side of the lesion, but a fine, low-amplitude, high-frequency primary-position nystagmus that increases as the patient looks to the side opposite the lesion.3 Bruns nystagmus primarily is a form of jerk nystagmus, characterised by alternating slow and fast components. official website and that any information you provide is encrypted Dabboucy B, Yazbeck M, Bassim M, Comair Y.

Bruns nystagmus is usually associated with large tumours of the cerebellopontine angle causing significant brainstem distortion, compression of the flocculus and/or vestibulocerebellum.1 In a study conducted on patients with unilateral vestibular schwannoma, the overall prevalence of Bruns nystagmus was estimated to be 11%.

Compression of the ipsilateral pons leads to a dysfunctional neural integrator (also the flocculus), which is unable to maintain eccentric gaze towards the side of the lesion, resulting in a high-amplitude, low-frequency, gaze paretic nystagmus.3 On the other hand, vestibular dysfunction leads to decreased tonic firing, which results in a slow-phase movement towards the side of the lesion with a compensatory fast-beating component in the contralateral direction.3 Knowledge of this rare variant of bidirectional nystagmus is important as it aids in making a prompt clinical diagnosis of cerebellopontine angle tumours. [1] It occurs in 11% of patients with vestibular schwannoma, and occurs mainly in patients with larger tumours (67% of patients with tumours over 3.5cm diameter).
