IOP Variations in the Sitting and Supine Positions [PDF]

Journal of Glaucoma, 2010
The aim of this study was to assess the influence of the position (upright vs. supine) in the intraocular pressure (IOP) measured with a non-contact portable tonometer.Fifty university students with a mean age of 22.3±4.2 years (mean±SD) were recruited to participate in this study. IOP was measured with the non-contact tonometer Keeler, Pulsair EasyEye.
