Anomalous retinal correspondence in esotropia.

The incidence of anomalous retinal correspondence (ARC) and the effect of strabismus surgery on ARC were investigated among esotropic patients. From the results obtained, we speculated that the critical period for the occurrence of ARC would be around the age of 3 years. The normalization of ARC was observed in 21% of the cases who underwent surgery. As the eye position in all the normalized cases was parallel or exotropic postoperatively, we speculated that the alignment or slight overcorrection of eye position is necessary for the ARC to be normalized.
