Covariation in Anomalous Correspondence with Accommodative Vergence

Key Points

To investigate the relationship between the angle of anomaly and the objective angle in a patient with exotropia.
Examined a patient with constant concomitant alternating exotropia.
Altered the objective angle using concave lenses to stimulate accommodation.
Measured the variations in the angle of anomaly corresponding to changes in the objective angle.
The angle of anomaly varied up to 31 Δ as the objective angle changed up to 37 Δ.
A perfect correlation (r = 1.00) was found between the two measured angles.

Abstract

Abstract In a patient with constant concomitant alternating exotropia at distance and near, the angle of anomaly varied in concert with the objective angle as the objective angle was altered by stimulating accommodative convergence using concave lenses to stimulate accommodation. The angle of anomaly was found to vary up to 31 Δ as the objective angle was varied up to 37 Δ. The correlation coefficient (r) between the two variables was 1.00. The implications of this finding are discussed.
