After a brief statistical survey the anotomic basis is explained in a broad outline. In the description of a case with bilateral paralysis of the abducens nerve, the suffering of the patient in his working life is examined and the phenomenon of inacurrate depth projection, of "pointing past", is discussed. As a result the suitability for employment is more highly reduced for those suffering from bilateral paralysis of the abducens nerve, as compared to persons with one eye. During the report a 16 mm Color film was shown, showing the patient before and after the O'Connor operation. The possibility of keeping a progress or control report, of patients suffering from inacurrate depth perception, was demonstrated.
