This has been widely studied on the measurement of blood-pressure; however its effect on IOP measurement has yet to be assessed. In order to achieve this, a pilot field study was conducted amongst fourteen volunteers taken from the customers of an optical centre in Barcelona. IOP measurements were performed at three stages: after a questionnaire phase, after optometry and after a recovery phase. The effect of threat and control perception linked to IOP was evaluated. Descriptive analyses suggest the existence of a white-coat hypertension effect on IOP measurements modulated by control perception linked to the measurement procedure. Finally, the possible applications and limitations of these findings are discussed.  a1134-7937  a2174-0437
