Intrasession and Intersession Variabilities of Intraocular Pressure Measured by Noncontact Tonometer in Normal Volunteers.

Purpose: Intraocular pressure (IOP) measured using a noncontact tonometer is evaluated by performing multiple measurements because IOP is affected by the ocular pulse. We investigated the relationship between value fluctuations in multiple measurements during noncontact tonometer measurements and cardiac rate.

Materials And Methods: Forty-two healthy subjects were included and IOP was measured using a noncontact tonometer.

Evaluation of Changes in Intraocular Pressure with a Noncontact Tonometer in Healthy Volunteers.

Purpose: We investigated whether or not intrasession or intersession fluctuations in intraocular pressure occur in healthy people using a noncontact tonometer.

Materials And Methods: A noncontact tonometer was used to measure intraocular pressure in the bilateral eyes of healthy subjects for 5 consecutive days. Paired -tests and one- and two-way repeated-measures analyses of variance were performed for the acquired data.
