The optokinetic reflex (OKR), also referred to as the optokinetic response, or optokinetic nystagmus (OKN), is a compensatory reflex that supports visual image stabilization. [1]

Optokinetic nystagmus (OKN) is a compensatory mechanism that functions to keep images of stationary objects on the retina during prolonged rotation of the head. The first phase (smooth pursuit) follows …

Jul 16, 2024 · Optokinetic nystagmus (OKN) is a reflexive eye movement in response to movement of the viewer's visual environment that consists of a slow phase eye movement in the direction of the …

The inability to produce symmetric optokinetic nystagmus (OKN) implies a dysfunction of the central vestibular system. It should be noted that to have a valid OKN test you must stimulate the patient’s …

Jun 23, 2025 · That reflex isn’t just a random twitch – it’s a sophisticated neurological response known as Optokinetic Nystagmus (OKN). Despite its apparent subtlety, OKN has a significant impact on …

Jan 27, 2018 · Optokinetic nystagmus (OKN) is a normal, physiologic type of nystagmus sometimes affected by disease. (1-4) OKN is conjugate nystagmus induced by a succession of moving visual …

Jul 26, 2025 · Optokinetic nystagmus (OKN) is a natural, involuntary eye movement occurring in response to a moving visual field. This reflex helps stabilize vision, preventing motion blur when …

Optokinetic nystagmus (OKN) and optokinetic after-nystagmus (OKAN) tests are common visual stimulation tests. OKN is induced when part of, or the entire visual field is continuously moving. It is …

Optokinetic nystagmus (OKN) is an oculomotor reflex closely linked to the vestibular system which contributes to the stabilisation of retinal images.

In this video, I introduce and explain optokinetic nystagmus, a normal phenomenon involving rapid movement of the eyes that occurs when relatively quickly moving objects pass by an observer. Video...
