Sensory retinal relationships in 100 consecutive cases of heterotropia. A comparative clinical study.

Abstract

One hundred consecutive patients with heterotropia were tested for the state of their retinal correspondence with a major amblyoscope, the striated lenses, and the after-image test. Of this group 84 responded with anomalous retinal correspondence (ARC) on the major amblyoscope, 50 had some form of ARC with the striated lenses, and 36 had some ARC with the after images. This evidence is interpreted in the classical fashion that the difference in response is due to the fact that the major amblyoscope test more nearly duplicates the conditions of casual seeing than does the after-image test. The data are analyzed also with regard to occurrence of ARC in patients with a deviation of 30Δ or less and with a deviation of more than 30Δ the prevalence of suppression, and of unharmonious ARC on the major amblyoscope.
