Perform the alternate prism cover test to accurately measure the angle of strabismus. This procedure gauges the full magnitude of any combined esotropia and esophoria. Carefully perform a prism cover testing for both distance and near fixation in primary position, with the patient wearing any prescribed spectacle correction. Measurement of the strabismus also is carried out in side and vertical gazes to rule out restriction, palsy, and significant oblique muscle overaction or underaction.
