Aural nystagmus is a condition where the eyes involuntarily move in response to sound. The spelling of this term can be explained using IPA phonetic transcription: /ˈɔːrəl nɪsˈtæɡməs/. The first syllable is pronounced like the word "oral," the second syllable is pronounced with the short "i" sound as in "pin," and the stress is on the second syllable. The final syllable is pronounced with the "a" sound as in "cat," and the stress is on the first syllable.
Aural nystagmus, also known as auditory nystagmus, refers to a neurologic condition characterized by abnormal eye movements that are elicited or influenced by auditory stimuli. Nystagmus involves involuntary rhythmic oscillations of the eyes, causing them to move rapidly and repetitively in one direction, followed by a slower return movement in the opposite direction.
Aural nystagmus occurs when an individual experiences eye movements triggered solely by sound stimuli. These eye movements may manifest as a quick horizontal or vertical darting, rhythmic oscillations, or jerking motions of the eyes in response to auditory input. While it is a rare occurrence, aural nystagmus can impact both children and adults.
The underlying mechanism of aural nystagmus involves a disruption in the normal coordination between the auditory and visual systems. It suggests a dysfunction in the neural pathways responsible for integrating auditory and ocular information, which results in inappropriate eye movements being triggered by sound stimuli.
The diagnosis of aural nystagmus typically involves a thorough examination of the patient's eye movements, focusing on their responses to auditory stimuli. Medical professionals may use specialized tests, such as videonystagmography or electronystagmography, to accurately evaluate the presence and severity of aural nystagmus.
Treatment options for aural nystagmus vary depending on the underlying cause and symptoms. Approaches may include addressing any underlying conditions, therapies to improve sensory integration, or surgical interventions in certain cases.
In summary, aural nystagmus refers to an abnormal eye movement response to auditory stimuli, indicating a malfunction in the coordination between the auditory and visual systems. Understanding the causes, symptoms, and appropriate treatment options for aural nystagmus is crucial for proper management
A spasmodic movement of the eyes, horizontal, vertical, or rotary, first rather slowly in one direction, then by quick jerking movements in the opposite direction, dependent upon labyrinthine disturbances.

The word "aural" is derived from the Latin word "auris" meaning "ear". It is often used to refer to anything related to the ear or hearing.
The word "nystagmus" is also derived from the Greek word "nystagmos", which means "drowsiness" or "to nod off". In medical terminology, it specifically refers to an involuntary, rapid, and repetitive movement of the eyes.
When combined, "aural nystagmus" refers to a form of nystagmus that is triggered by auditory stimuli or sound.
