A marked and highly significant reduction was observed in the pulsesynchronous change in intraocular pressure in normal pregnancy, as recorded by dynamic tonometry. The decrease in corneal indentation pulse amplitudes most probably reflects a change in the peripheral vascular resistance. It is suggested as a new and characteristic sign of pregnancy. In addition, a minor decrease of the intraocular pressure was found, with no concomitant change in ocular rigidity.
