Chin-brow vertical angle
WebChin-brow vertical angle was an objective index for evaluating horizontal gaze. Based on the results of this study, measurement of chin-brow vertical angle is recommended for planning correction of kyphosis and accurate evaluation of treatment outcome. AB - Study Design. A prospective study. WebHorizontal gaze is classically measured by the chin-brow vertical angle (CBVA), which is not readily measured on most lateral spine radiographs. OBJECTIVE: To evaluate relations between CBVA and the slope of the line of sight, the slope of McGregor's line (McGS), and Oswestry Disability Index.
