Intra ocular pressure in normotensive and hypertensive subjects of same age group

Abstract

Intra ocular pressure (IOP) is pressure exerted by aqueous humour. Aqueous humour maintains shape and nutrition of the eye ball. IOP is affected by various factors. Systemic hypertension affects formation and circulation of intra ocular fluid. Elevated IOP may lead to glaucoma and then to blindness. In this study intra ocular pressure and blood pressure were compared in normotensive and hypertensive subjects of same age group. 100 male and female subjects of age group 45- 55yrs with normal blood pressure and 100 male and female subjects of age group 45-55yrs with newly diagnosed hypertension were included in the study. IOP measured using Perkin’s applanation tonometer. Blood pressure measured in supine position. Statistical analysis was done by Pearson’s coefficient correlation and unpaired‘t’ test. Mean IOP recorded in both right and left eye was equal. IOP showed linear correlation with systolic blood pressure and diastolic blood pressure. Mean IOP in hypertensive was more than mean IOP in normotensive subjects. Elevated systemic blood pressure is responsible for raised IOP which can progress to glaucoma. So to increase awareness regarding ocular complications of hypertension is important.
