The effects of moderate-level altitude change on intraocular pressure

This study investigated the relationship between short duration moderate-level altitude changes and changes in the internal pressure of the eye. The Mentor Tono-Pen™ was used to measure intraocular pressures of seventeen non-glaucomatous patients at ground level, in a plane at 5,000 and 10,000 feet, and again at ground level. A repeated measures analysis of variance (P\u3c0.05) was used to analyze the data. Altitude change was found to have no significant effect on intraocular pressures of subjects in this study
