Ophthalmodynamometry is a technique for
measuring the blood pressure
in the small blood
vessels of the retina
of the eye.
An instrument is pressed against the eye until the retinal blood vessels
are observed collapsing. The pressure recorded by the instrument at that
time reflects the pressure within those blood vessels in the retina. (However,
there are certain disorders of blood circulation in the eye in the cases
of which the pressure in the vessels is reduced - with the effect that
they can be caused to collapse by a lower than normal pressure on the
eyeball.)
