'Gaze' and specialised knowledge

I believe 'gaze' was first introduced by Foucault in 'The Birth of the Clinic' (1973) where it referred to the 'medical gaze' which transformed the body into a positivists object. That specialised knowledge selected and constructed a particular object, on the basis of recognition and realisation procedures internal to the specialisation of that knowledge.
