Purpose:
|
To determine the distribution of IOP, CCT, and vertical cup to disc ratio (VCDR) in a healthy Iranian population.
|
Methods:
|
In this Cross-sectional, epidemiologic study on adults, aged 40 to 80 years, eligible subjects were selected using cluster random sampling.
|
Results:
|
Out of 2,320 eligible individuals, 2,098 subjects (response rate of 90.4%) participated in the study. From this population, 2,262 normal eyes from 1,159 subjects were selected for the purpose of the study. Mean age was 53.1 ± 9.6 years. Mean values for IOP, CCT, and VCDR were 14.2 ± 2.5 mmHg, 543 ± 35 µm, and 0.32 ± 0.14 respectively. Multiple regression analysis showed a significant correlation between IOP and age, CCT, diabetes mellitus, spherical equivalent refractive error, and smoking.
|
Conclusion:
|
The distribution of IOP, CCT, and VCDR in YES was different from other studies in different geographical regions; it seems advisable to employ a geographical approach for interpretation of normal variables.
