High blood pressure is not only associated with systemic cardiovascular complications, but also, ocular complications such as glaucoma. This study sought to determine the association between blood pressure, intraocular pressure and glaucoma. In this cross-sectional study, 162 hypertensive patients (with mean age of 57 (±14.26) years) visiting the St. Dominic’s hospital, in Ghana were purposively sampled to participate in the study. Data on patient’s history, blood pressure, intraocular pressure and cup-to-disc ratio were collected and analysed using Statistical Package for Social Sciences (SPSS) version 20. Descriptive statistics was computed and thestatistical significance of associations was assessed at a significance level of 0.01. The outcome of the study revealed a positive correlation of 0.364 and 0.309 between systolic blood pressure and the intraocular pressure of the right and left eye respectively.The correlation between diastolic blood pressure and intraocular pressure of the right and left eyes were 0.334 and 0.239 respectively. Out of the 104 patients with systolic blood pressure exceeding 139mmHg, 54 of them (51.9%) had intraocular pressures greater than 21mmHg and 58 of them (55.8%) had cup-to-disc ratio in the range of 0.7–1.0. A weak but positive correlation between systolic blood pressure and cup-to-disc was also established.Last but not least,a correlation of 0.441 between intraocular pressure and cup-to-disc ratio of the right eye of participants as against a correlation 0.256 for the left eye was reported.The susceptibility to glaucomawas thus, relatively high in patients withuncontrolled hypertension and higher intraocular pressure.Hence, pragmatic measures should be takenby all stakeholders towards managing hypertension and intraocular pressurein order to safeguard the health and sight of all.
