Intraocular pressure response to gradual onset of extreme normobaric hypoxia
Original language description
BACKGROUND: During many sports, the organism is exposed to hypoxia. Exposure to hypoxia, such as staying at high altitudes, affects intraocular pressure (IOP), which is one of the most monitored parameters connected with glaucoma. This paper assesses the IOP response to a gradual onset of normobaric hypoxia and its acute termination. METHODS: Thirty-six subjects (2911 years) performed the complete test. The observed parameters were IOP, arterial oxygen saturation and corneal thickness (CT). After measurements in normoxia, subjects entered a normobaric hypoxic chamber with a simulated altitude of 2000 m which increased up to 5000 m during 77±7 min. After exposure (18±2 min) in the final altitude, the subjects left the chamber. RESULTS: The IOP significantly dropped after leaving the chamber up to 15.7±2.7 mmHg in comparison with the simulated altitude 5000 m (17.5±3.4 mmHg). The step change from normoxia to a simulated altitude (2000 m) and its gradual increase up to 5000 m did not affect IOP significantly. The CT did not change during the experiment. CONCLUSIONS: Gradual increase in hypoxia over tens of minutes does not affect IOP significantly, whereas a sudden departure from the hypoxic chamber with a simulated altitude of 5000 m causes significant changes in IOP. This IOP variation could be potentially health issue e.g. for glaucoma patients.
