[Gamma resonance velocimetry of the eye]

A new method for the registration of ocular orbital pulse in humans is suggested, based on the nuclear gamma resonance effect. In normal subjects the velocity of the corneal movement over the period of a cardiac contraction is under 0.3 mm/s, and the mean amplitude of corneal transposition is 21.8 +/- 0.6 microns. The amplitude of corneal transposition and the cardiac cycle length are in square relationship.
