title: Correlation between Age, Gender, Waist-Hip Ratio and Intra Ocular Pressure in Adult North Indian Population.
abstract: BACKGROUND
  Intraocular pressure (IOP) is affected by various systemic and local factors. The significance of studying the factors affecting IOP is because of its association with potentially blinding condition known as glaucoma.
  
  
  OBJECTIVE
  Present study was conducted with the aim to find out the correlation between gender, age, Waist-Hip Ratio (WHR) and IOP.
  
  
  METHODS
  The study included 300 healthy individuals between 40-79years of age. The subjects were divided into 2 categories according to gender i.e., male and female. The subjects were divided into 4 categories according to age i.e., 40-49years, 50-59years, 60-69years and 70-79years. The subjects were divided into two groups according to Waist-hip ratio (WHR) as per WHO guidelines: WHR <0.9 and WHR >0.9 in males and WHR <0.85 and WHR >0.85 in females. IOP was recorded in each group using Goldmann Applanation tonometer and statistical comparisons were made to find correlation between gender, age, Waist-hip ratio and IOP.
  
  
  RESULTS
  There was no statistically significant difference between IOP of males and females (p=0.235). The age and IOP were positively correlated with each other i.e., IOP increases with increasing age (r=0.511, p<0.001). Higher WHR is associated with significantly higher IOP in both the genders (males r =0.644, p<0.001; females r=0.794, p<0.001).
  
  
  CONCLUSIONS
  There is no significant difference in IOP amongst males and females. Increasing age and higher WHR are risk factors for raised IOP.
