Accurate measurement of eye movements with little load on subjects is highly demanded in neuroscience as oculomotor control is a popular model system to investigate biological motor control mechanisms. Video oculogramusing real time image processing is suitable for this purpose. This article surveys recent progress in the measurement of 3 dimensional eye movements (yaw, pitch, roll rotations), particularly those using real time image processing techniques. We summarize the technique for the pupil extraction that determines the gaze direction by providing eye position in yaw and pitch planes. The technique to measure ocular rolling (cycloduction) is also summarized.
