Background & Objectives: Intraocular pressure (IOP) refers to the pressure exerted by intraocular fluids on the coats of the eye ball. Normal IOP is essentially maintained by the dynamic equilibrium between the rate at which aqueous humour enters the eye and the rate at which it leaves the eye . When inflow and outflow were equal, steady state exists and the IOP remains constant. Elevated intraocular pressure often results from alterations in aqueous humor dynamics due to change in trabecular meshwork. Increased IOP which is seen in primary open angle glaucoma is caused by a decreased facility of aqueous humor outflow. Materials & Methods: The total subjects participated in this study were 60 men. (30 normotensive & 30 hypertensive individuals). The subjects with age between 36years and 65years were included. Results : The mean intraocular pressure of normotensive subjects in the age group 35-65 years in right eye was 14.27 ± 2.25 mmHg and 14.94 ± 2.03 mmHg in the left eye .The mean intraocular pressure of hypertensive subjects in the age group 35- 65 years in right eye was 16.40 ± 2.24 mmHg and 16.77± 2.27 mmHg in the left eye . Conclusion: When we compared the intraocular pressure of right eye & Left eye between normotensive and hypertensive groups, we found statistically significant increase in the intraocular pressure in hypertensive’s in both the eye’s . ( p value = 0.0005 Right eye; p value = 0.0017 Left eye - unpaired t test ).
