Changes in retinal correspondence after changes in ocular alignment

We studied the changes in retinal correspondence for 32 constant strabismic patients whose ocular alignment was altered either surgically or spontaneously over a period of time. Patients having normal retinal correspondence (N = 10) generally maintained normal correspondence after the change in ocular alignment. Patients with anomalous retinal correspondence (N = 20) behaved differently. Thirteen of these patients maintained anomalous correspondence and seven patients developed normal correspondence after the change in ocular alignment. For the patients who developed normal correspondence, the direction of the strabismus also changed. We conclude that normalization of retinal correspondence is more likely to occur in strabismic deviations that are overcorrected.
