This study explored a new technique for measuring fixation disparity. The concept quantified superimposition of physiologically diplopic images to determine alignment of the subjects' visual axis and fixation disparity. Fifteen subjects were tested using the new Laser Disparometer and the Sheedy Disparometer. Results showed a 0.88 correlation between the two methods and no significant difference between mean fixation disparity measurements. Future studies are needed with larger sample size to increase statistical support for the Laser Disparometer.
