Online published on 16 April, 2015. Abstract Intraocular pressure varies throughout the night and day. The diurnal variation for normal eyes is between 3-6mmHg and the variation may increase in glaucomatous eyes. Hence, we wanted to investigate the effect of exercise on intraocular pressure changes in relation to Body Mass Index. The effect of exercise on intraocular pressure and blood pressure was evaluated in our clinical laboratory in 30 voluntary 1st year Medical Students of Basaveshwara Medical College, Chitradurga, after the institutional ethical clearance. Materials used in the study were Schizont tonometer, Measuring tape, Weighing Scale, Treadmill and Paracaine eye drops. After a resting period, the subject's height and weight were recorded. Paracaine eye drops were instilled in both the eyes and then intraocular pressure recorded using Schizont Tonometer after 2 min so that anaesthetics acts. Then they were asked to walk on Treadmill with average speed till they were exhausted, again intraocular pressure was noted as above with all aseptic precautions. The statistical analysis was done using students unpaired t-test using SPSS software. Results were expressed in terms of Mean and Standard deviation. P value was taken significant at 5 percent confidence level (p<0.05). Results Intraocular pressure was measured according to BMI under two groups, first with group having BMI less than 22 and other in group having BMI more than 22. There was a significant decrease in intraocular pressure after exercise in group two with BMI more than 22. Gender wise comparison of intraocular pressure both before and after exercise did not reveal much significance. Blood pressure was also recorded both before and after exercise which did not reveal any significance in relation to BMI. From our study we conclude that exercise has significantly decreased the intraocular pressure and has a correlation with body mass index in young age group.
