Campimetry is a method (technique) for
examining and assessing the central part of a person's visual field.
The subject (in a experiment, or "patient" in a clinical situation)
concentrates one eye on a target at the centre of a black screen two metres
ahead. A small lighter-coloured object is then brought into his/her field
of view and the subject reports when he/she first sees it. This process
is repeated with the object being brought into the subject's field of
view from many different directions in order to build-up a map of the
the subjects field of view using that eye alone.
The procedure may be repeated for the other eye as the size and shape
of the subject's visual field may not be the same for each eye.
