IN 1934 Braun1 called attention to the fact that the normal "blindspot," resulting from the absence of perceptive elements in the optic papilla, may form the nucleus of a suppression scotoma in the squinting eye. Seven cases of esotropia are now reported as representative of a clinical entity in which the physiologic blindspot seems to play an exceptional role as a central scotoma in the squinting eye. Recognition of the "blindspot" syndrome is important because it seems common and remediable. Restoration of comfortable single binocular vision results if treatment is properly directed, whereas partial or improper measures are of little benefit and may add to the patient's distress.

Recognition of this syndrome resulted from determination of the field of binocular vision in 296 cases of concomitant esotropia in older children and adults. The field of binocular vision was plotted by the use of colored filters and twin projection systems
