Psychoanalytic data, free associations, and dreams enable the analyst to follow the vicissitudes of conflict as expressed in visual functions.

Various defects may follow one another: field defects, scotomata, size distortion, color misperceptions. Color in dreams in those with neurotic dyschromatopsia fulfils the wish for healthy visual functioning. There is a close link between ocular perception and oral strivings.
