Figure 6From: A high-resolution binocular video-oculography system: assessment of pupillary light reflex and detection of an early incomplete blink and an upward eye movement Example of the upward pupil movement. a) The first frame and b) the frame at 0.1 seconds after the flash shot, for one example pupil. The red line represents the initial position and the green dashed line represents the position at t = 0.1 s, clearly depicting the upward movement of the eye (Bell’s phenomenon) and the shadow of the upper eyelid (incomplete blink).Back to article page
