Correlation of pupil to limbus diameter ratio (PLD ratio) with blood pressure and pulse rate in underweight females

Abstract

There are no studies where the pupil to limbus diameter ratio was assessed in the underweight individuals. Hence, the present study was undertaken to observe the correlation of pupil to limbus diameter ratio (PLD ratio) with blood pressure and pulse rate in underweight females. A total of 30 underweight females were included in the present study after obtaining voluntary informed consent by convenient sampling. PLD ratio was measured manually by the two-box method. There was a positive correlation between the PLD ratio of the right eye with the blood pressure and pulse rate. However, it was not statistically significant. There was a negative correlation between the PLD ratio of the left eye and pulse rate but it was not statistically significant. There was a positive correlation between the PLD ratio and systolic blood pressure. However, it was not statistically significant. There was a positive correlation between the PLD ratio and diastolic blood pressure. However, it was not statistically significant. The study results suggest the correlation between the PLD ratio and the blood pressure and pulse rate. The insignificant of results may be due to less sample size.
