Actual measurement of fixation disparity and its use in diagnosis and treatment.
An instrument and technique are described which, for the first time, enable the eye care practitioner to measure the angle of fixation disparity. A forced vergence fixation disparity curve can be quickly measured in the office. Research findings and patient examples are used to show how a fixation disparity curve is analyzed to diagnose and prescribe for an oculomotor imbalance.
