White and Brown (1939) found the following distribution in 1,062 cases : uncomplicated lateral deviation in 347 patients, uncomplicated vertical deviation in 358, and combined vertical and lateral deviation in 357. Dunnington and Regan (1950) found that 50 per cent. of 79 cases of concomitant convergent strabismus showed a vertical component. Scobee (1951), in 457 cases of convergent strabismus...

BACKGROUND AND PURPOSE Patients with right hemispheric stroke usually present an anticlockwise deviation of the subjective visual vertical (SVV) in the frontal (roll) plane. However, the occurrence of a similar disorder in the sagittal (pitch) plane has never been assessed. We investigated the subjective visual vertical in both planes in those patients. METHODS Eight patients, 4 with spatial ...

Factors affecting manual discrimination of spatial orientations and orientation preferences in 5-month-old infants have been investigated by using a familiarisation/reaction to novelty procedure. In the first experiment we explored whether the 'vertical preference' observed by Gentaz and Streri (2004 Journal of Cognitive Neuroscience 16 1-7) and Kerzerho et al (2005 Neuro Report 16 1833-1837) i...

INTRODUCTION The capacity of a healthy individual to estimate the true vertical in relation to the Earth when a fluorescent line is aligned in a completely dark room is called the subjective visual vertical. OBJECTIVE To evaluate subjective visual vertical using the bucket method in healthy Brazilian individuals. METHODS Binocular subjective visual vertical was measured in 100 healthy volun...
