Abstract
This eye-movement recording system uses the scleral search coil technique. It has two recording channels, which is extremely important in the binocular vision studies. It consists of four basic elements: magnetic field coils to generate horizontal and vertical oscillating magnetic fields, two ocular search coils to detect the eye positions, an eye movement monitor to separate and amplify the horizontal and vertical eye-movement signals, and a PDP11/23 data acquisition system to digitize the eye position signals and store them on the disk. Several programs analyze and plot the data. This system has recorded eye movements from normal subjects with high resolution, linearity, low drift, and low noise, when compared to other methods.
This system will be used in ophthalmological clinical and basic research.
