A 6-month-old baby presented with gaze deviation to the right since birth. When attempting to look straight ahead, his head was deviated to the left. Pregnancy and delivery were unremarkable. No other signs of eye dysfunction were observed. Neurologic examination showed mild motor asymmetry ...
Then and Patel (8) presented a unique case of a 65-year-old woman diagnosed with stage 4A Kappa restricted B Cell MCL who presented with acute-onset double vision, skew deviation of the eyes, left eye ptosis, right horizontal gaze palsy, right facial droop, dysarthria, and dysphagia 2 mon...
26). In the literature examining the visual-motor control of steering, the functional role has been most commonly tied to thetime headwayof gaze: the time it would take to locomote to the point in the world where gaze falls13. Theories of the visual control of steering (derived...
1b. Thus, with greater standard deviation, there is more uncertainty about the centre of the target; the greater the uncertainty, the more information the subject stands to gain by resolving this uncertainty27. This approach is commonly used to manipulate uncertainty of visual targets in studies ...
shifts of the looker. Yet, under less ideal conditions (e.g., when the looker does not face the observer directly but with a turned head), both the average error and standard deviation of observer judgements increased (Cline,1967), although only the average error, not the standard deviation...
Due to the existence of gaze deviation, the lines of sight of the left and right eyes usually do not intersect most of the time. In this case, the VOR &Gaze depth Recent researchers [25] have pointed out that the relative head and eye movements during VOR may be a helpful clue for ...
Overall, fast walkers were less likely to slow down throughout all step regions, while slow walkers slowed down in all step regions. This individual difference in stride duration contributed for the large standard deviation in stride time observed in Fig. 3b. Finally, Fig. 4c shows ...
Figure 3.Esodeviation, which is greatest in the right gaze. Dilated fundus examination revealed optic discs with distinct margins and no evidence of edema. There was 0.3 × 0.3 cupping in the right eye and 0.3 × 0.3 cupping in the left eye. The neuroretinal rim was intact and pink in ...
1c), and in a deviation from the analysis plan, the eye region was primarily used for all further analyses (analyses involving the mouth region are reported in Supplementary Information S1). Lateralization was measured as the total amount of time looking at the left hemiface relative to the ...
The images presented for the VIS task had a mean (standard deviation) length in their largest dimension of 0.60 m (0.07 m) and visual angle of 17.2° (2.2°). Participants were not instructed on the speed required to complete the visual task but were asked to try to keep their ...
