The order of magnitude of the fields is generally red, yellow, blue, green, violet. The red field is the largest, and is characteristic of this dyschromatopsia. Anomalies of the visual fields are not necessarily found in all cases of traumatic neurosis, nor can anomalous fields serve exclusively for the diagnosis of that affection.
