Eye contact plays a central role in face-to-face interviews. As the main perceptual support for the therapist-patient relationship, it is cathected with a libidinal charge whose sources are as much genital as infantile. The patient's gaze may sometimes disturb the analyst, when its sexual component is poorly repressed, as in the case of perverse transference. This bodily experience in the countertransference can prove positive in certain cases, when it sets thoughts that have been impeded moving again; it can even help with the diagnosis, and relaunch a stagnant therapeutic dynamic: such is the challenge of this work, based on the analysis of two clinical encounters.
