Retinal correspondence in patients with small degree strabismus

THE RELATIONSHIP of anomalous retinal correspondence, angle of strabismus and amblyopia is confused in the literature. It is stated (Adler and Jackson1; Travers2) that the incidence of anomalous correspondence increases as the angle of strabismus becomes greater and that anomalous correspondence is seldom found in esotropia of less than 15 Δ. Thus, a detailed study of patients with small angle esotropia is interesting from a theoretical and practical standpoint, because the correct sensorial relationships are difficult to evaluate and consequently lead to many erroneous conclusions. It is the purpose of this article to point out some of these errors in interpreting the sensorial relationships found in cases of small angle esotropia and to compare these conditions with those found in cases with which they are often confused.
