Objectives: 1) To compare the incidence of elevated visually enhanced vestibular‐ocular reflex (VVOR) rotational gain during rotational chair testing in a normal control group versus a group of patients diagnosed with migraine vestibulopathy; 2) to discuss the possible application of VVOR gain during rotational chair testing for diagnosing migraine vestibulopathy.

Se hela listan på emedicine.medscape.com All patients also underwent four other pretreatment tests: videonystagmography to evaluate the vestibulo-ocular reflex, static posturography to test the vestibulo-spinal reflex, computed tomography (CT) and/or magnetic resonance imaging (MRI) of the head to look for pathology, and Doppler echo testing on the cerebroafferent vessels. To maintain a clear and stable view of the environment, we use reflexes to rotate our eyes in a direction that is opposite to any head motion that occurs.

Head impuls test (HIT) är ett kvalitativt VOR-test där patienten ska Angular vestibulo ocular reflex (aVOR) bygger på liknande princip som HIT

VOR består. This maneuver tests the vestibulo-ocular reflex (VOR).

The vestibulo-ocular reflex (VOR) ensures best vision during head motion by moving the eyes contrary to the head to stabilize the line of sight in space. The VOR has three main components: the peripheral sensory apparatus (a set of motion sensors: the semicircular canals, SCCs, and the otolith organs), a central processing mechanism, and the motor output (the eye muscles).

An indirect system identification technique for stable estimation of continuous-time parameters of the vestibulo-ocular reflex (VOR) (211) (1).

This reflex functions to stabilize images on the retinas (in yoked vision) during head motion by producing eye motions in the instructions opposite to head movement, hence maintaining the image on the center of the visual field (s). vestibulo-ocular reflex nystagmus or deviation of the eyes in response to stimulation of the vestibular system by angular acceleration or deceleration or when the caloric test is performed. The ‘ear to eye’ connection is known as the vestibulo-ocular reflex (VOR). The VOR has a critical role of keeping the eyes still during head motion. This is known as gaze stability.

This reflex functions to stabilize images on the retinas (in yoked vision) during head motion by producing eye motions in the instructions opposite to head movement, hence maintaining the image on the center of the visual field (s). The particular interest in the torsional vestibulo-ocular reflex arises from new methods for measuring ocular torsion, especially the three-dimensional eye-movement recordings with scleral coils. These methods make it possible to do three-dimensional analysis of the differential effects of horizontal and vertical semicircular canal function and their individual disorders of the torsional vestibulo-ocular reflex. 2017-02-24 To maintain a clear and stable view of the environment, we use reflexes to rotate our eyes in a direction that is opposite to any head motion that occurs.

Recent animal and clinical studies on the vestibulo-ocular reflex deal with a number of physiological and clinical aspects from which three were chosen for this review: (1) the torsional vestibulo-ocular reflex and its disorders; (2) the otolith contribution to the vestibulo-ocular reflex; and (3) n … Vestibulo-okulära reflexen - då huvudet rör sig måste ögonen röra sig åt motsatt håll för att inte synintrycket skall bli skakigt och omöjligt att extrahera information utifrån.

Den på senare tid beskrivna, för tillståndet typiska bilden med bilateralt bortfall av horisontell vestibulo-okulär reflex testas lämpligen med kliniskt vestibulärt impulstest (head impulse test; HIT) eller ännu hellre video-HIT (vHIT).
