Abstract

Objective: To study and compare the effect of Isotonic and Isometric exercise on Ocular Perfusion Pressure (OPP) in healthy young adults. Method: 40 healthy young adult volunteers comprising 20 males and 20 females in the age group of 18-21 years were selected among MBBS Phase I students of JSS Medical college, Mysuru. Isotonic exercise was performed using a treadmill, and isometric exercise was performed with a Digital back-leg lift dynamometer. IOP and BP were recorded before and after performing exercises using standard methods. Mean arterial pressure (MAP) and OPP were calculated. Statistical analysis was done using paired t test and ANOVA to test the difference between the groups. Results: OPP increased by 11.27±1.33 mm Hg after isotonic exercise and by 6.82±0.02 mm Hg after isometric exercise. The changes were statistically significant (P< 0.001). Conclusion: There was a significant increase in OPP after performing both Isotonic and isometric exercises. Moderate intensity Isotonic exercise proves to be beneficial for ocular health as it improves ocular perfusion.
