Abstract

Background & objectives: Intra ocular pressure (IOP) is influenced by various Physiological variables in the body system like age, sex, diurnal variation, and pregnancy etc. Exercise when performed regularly has beneficial effect on the various systems of the body and Exercise is known to affect IOP, hence this is study is undertaken to know the physiological effect of isometric exercise on IOP.

Methods: IOP was recorded by using Schiotz tonometer in 30 healthy male subjects before and after isometric exercise which was done by using hand grip dynamometer at 20% and 40% of predetermined MVC respectively. The results obtained were compared between before and after exercise of the subjects. The statistical analysis of IOP variations was done by using student’s t- test.
Results: There was a statistically significant reduction in IOP after exhausting isometric exercise. The mean IOP significantly decreased (p<0.05), immediately and after 5 minutes of 20% and 40% of predetermined MVC when compared to the IOP recorded before exercise. The mean IOP difference between 20% and 40% of predetermined MVC were also statistically significant (p<0.05) when recorded immediately, and after 5 minutes of exercise, suggesting that exercise causes reduction in IOP.
Conclusion: This study conclude that exercise has significantly decreased the intraocular pressure, advising exercise might be useful to glaucomatous patients.
