“…This phenomenon is probably related to short-term visual memory and similar to visual dependency at rod-and-frame test. We defined the effect as visual attraction, and showed that it was higher in children, teenagers, and senior patients in comparison to middle-aged adults (10). We also observed a higher attraction in women versus men.…”

“…In a previous study, we showed that VVS was attracted to the side of bar presentation and this effect varied with age and sex (10). This phenomenon is probably related to short-term visual memory and similar to visual dependency at rod-and-frame test.…”

“…A phenomenon equivalent to visual attraction has been largely studied by the ''rod-and-frame'' test (5,10). The position of a tilted frame constantly present on the screen influences the estimation of the vertical and is defined as visual dependency.…”

“…In a previous study (10), we reported the influence of age and sex in a large population (n ¼ 6,931) predominantly composed of adult patients (mean age 55 years). We showed that the phenomenon of visual attraction was maximal in both age extremes and that in young and midaged adults (20-50 years) the attraction was negligible in both sexes.…”

“…As such, the rod was initially presented either approximately horizontal or slightly sloped to either left or right of the horizontal line. The initial orientation was ran domly sampled from the following set of angles: ±45 o , ±55 o , ±65 o , ±75 o and ±85 o as the rod presentation can impact results as well (Toupet, Van Nechel & Grayeli, 2015).…”

Background: Visual-vestibular and postural interactions can act as cues that trigger motion sickness and can also have a role in some anxiety disorders. We explore a method to detect individual sensitivity to visual-vestibular unusual patterns, which can signal a vulnerability to develop motion sickness and possibly anxiety disorders such as a fear of heights and panic. Material/Methods: 65 undergraduate students were recruited for the purposes of this study as voluntary participants (44 females); average age 21.65 years (SD=2.84) with normal or corrected to normal vision, without vestibular or postural deficiencies. Panic was assessed with the Albany Panic and Phobia Questionnaire, Motion Sickness with the Motion Sickness Susceptibility Questionnaire and Acrophobia was assessed by means of the Acrophobia Questionnaire. The Sharpened Romberg Test was used to test participant’s postural balance. The Rod and Frame Test (RFT) measures the participant’s ability to align a rod to the vertical within a titled frame providing a measure of error in the perception of verticality by degrees. This test was changed to measure the error offered when a participant’s head was tilted, and to trace the error caused by manipulating the vestibular system input. Results: The main findings show only motion sickness to be correlated with significant errors while performing a visual-vestibular challenging situation, and fear of heights is the only anxiety disorder connected with postural stability, although all disorders (fear of heights, panic and motion sickness) are correlated between each other in the self-report questionnaires. Conclusions: All disorders are correlated to each other in the surveys, and might have some common visual-vestibular origin, in theory. The rod and frame test was exclusively correlated with motion sickness whereas the postural stability test only displayed sensibility to acrophobia. Panic disorder was correlated to neither the RFT nor the Romberg. Although this method was initially employed to increase sensibility in order to detect anxiety disorders, it ended up showing its value in the detection of motion sickness.

Objective Eye tracking technology has been employed in assessing ocular motor and vestibular function following vestibular and neurologic conditions, including traumatic brain injury (TBI). Assessments include tests that provide visual and motion (rotation) stimuli while recording horizontal, vertical, and torsional eye movements. While some of these tests have shown diagnostic promise in previous studies, their use in clinical practice is limited by the lack of normative data. The goal of this study was to construct normative reference ranges to be used when comparing patients' results. Methods Optokinetic response, subjective visual horizontal and vertical, and rotation tests were administered to male and female volunteers, ages 18‐45, who were free from neurological, vestibular disorders, or other head injuries. Tests were administered using either a rotatory chair or a portable virtual reality‐like goggle equipped with video‐oculography. Results Reference values for eye movements in response to different patterns of stimuli were analyzed from 290 to 449 participants. Analysis of gender (self‐reported) or age when grouped as pediatric (late adolescent; 18‐21 years of age) and adult (21‐45 years of age) revealed no effects on the test metrics. Data were pooled and presented for each test metric as the 95% reference interval ( RI ) with 90% confidence intervals ( CI ) on upper and lower limits of the RI. Conclusions This normative database can serve as a tool to aid in diagnosis, treatment, and/or rehabilitation protocols for vestibular and neurological conditions, including mild TBI (mTBI). This database has been cleared by the FDA for use in clinical practice (K192186). Level of evidence 2b

Subjective Visual Vertical Tilt Attraction to the Side of Rod Presentation

Abstract: These effects suggest that short-term visual memory and multisensory cortical processing interfere with SVV measurements.
