Objectives:
A prospective study to evaluate the effect of 10% Phenylephrine eye drops on systemic blood pressure in normotensive and hypertensive patients.
Methods:
The sample comprised of 55 normotensive patients and 34 hypertensive patients were subjected to 10% Phenylephrine eye drops during routine eye examination.
Results:
No statistically and clinically significant increase in blood pressure after the instillation of 10% Phenylephrine eye drops was seen in 87% of normotensive patients and 76% of hypertensive patients. Mild rise of blood pressure was seen in 11% of normotensive patients and in 15% of the hypertensive patients. Only one patient (3%) had severe rise of blood pressure in the hypertensive group.
Conclusion:
This study shows that pupillary dilatation with 10% Phenylephrine eye drops did not significantly increase systemic blood pressure in normotensive and hypertensive patients. Although precautions should be taken when used in hypertensive patients.

Blood Pressure
The average BP in an adult is typically around 120/80 mmHg (millimeters of mercury). In this measurement, the numerator (120) indicates the systolic pressure, which is the pressure in the arteries during the contraction of the heart's ventricles as blood is expelled. The denominator (80) represents the diastolic...
