“…When only the first two measurements were considered for each participant, the data were not normally distributed, and Spearman correlations were conducted. Similarly, normative data 20 for use in clinical settings were also calculated as the mean of two measurements from each direction for each individual, and medians and percentiles (10 to 90%) were determined for each distance (Table 2) because the data were not normally distributed.…”

“…15 In addition to individuals who had a cerebrovascular accidents, visual midline shift has been reported in individuals with other neurological disorders such as Parkinson's disease 19 and traumatic brain injury. 20 Visual midline shift in the horizontal dimension and its associations with other measures of egocentric perception such as subjective straight-ahead, visual open-loop pointing, and spatial neglect have been studied in the past 50 years, and there have been studies to assess these in controls and populations with spatial neglect. The estimated prevalence of spatial neglect (visual neglect) after a unilateral stroke is 30%.…”

Significance Visual midline shifts are thought to occur post-stroke and be a risk factor for falls. This study investigates a new method for quantifying visual midline shifts, a first step toward developing greater understanding of visual midline shift. Purpose This study standardized the parameters of a novel visual midline gauge, compared the results with the current clinical method, and presents normative data and repeatability of both methods. Methods Ninety-three participants without neurological or ocular problems were recruited in Canada and Hong Kong. In experiment 1, horizontal and vertical visual midlines were measured using the gauge for two speeds and two repositioning methods. In experiment 2, visual midline was measured for three distances using a target speed and repositioning method chosen based on the first experiment. Visual midlines were also measured using the current clinical method during both visits. Results There were no significant effects of age, speed, study location, or repositioning method on visual midline positions (all p>0.05). For the horizontal direction, measurements at 25 cm were different from those at 50 (p=0.03) and 100 cm (p=0.001). For the vertical direction, there was no such effect. The measurements were found to be repeatable to within approximately 3°. In both visits, there were significant correlations between measurements using the visual midline gauge and the clinical method for the vertical direction (all p<.001) but not for the horizontal direction (all p>0.05). Conclusions The measurement of visual midline is tolerant of differences in target speed, testing method, and age of the participants, and the visual midline gauge measurements are repeatable.
