MEAN INTRAOCULAR PRESSURE IN HYPERTENSIVE ADULTS

Intraocular Pressure in Hypertensive Adults

Abstract

Objective: To determine the mean Intraocular Pressure (IOP) in already diagnosed adult hypertensive patients with different grades of hypertension.

Study Design:  Cross-sectional descriptive study.

Place and Duration of Study:  Combined Military Hospital, Lahore, from March 2012 to Aug 2012.

Patients and Methods: A total of 178 already diagnosed hypertensive patients were selected. A detailed history of ocular or systemic diseases was taken. Intraocular pressure was measured with help of Goldmann applanation tonometer. Three consecutive readings of IOP of each eye were taken at 30 minutes interval and mean calculated. Blood pressure was recorded in seated position from right upper arm, by mercury sphygmomanometer. Blood pressure measurements were determined by taking the mean value of three systolic and diastolic readings.

Results: The results of intraocular pressure (IOP) between various grades of hypertension were determined. There was an increase in mean IOP with rise in blood pressure. The subjects with grade I hypertension showed a mean IOP of 13.95 ± 3.74 mmHg, while grade II and grade III hypertensive subjects had mean IOPs as 18.10 ± 3.32 and 20.21 ± 2.52 mmHg respectively.

Conclusion: A higher value of mean IOP was found with increase in systolic and diastolic blood pressures.
