Abstract
Aim: To determine the normal and extremes of values for interpupillary distance [IPD] amongst adults in Ogun State, South Western Nigeria.
Methodology: A population based cross-sectional study. Multi-staged stratified random sampling was used to select respondents from seven Local government areas in Ogun State.
Results: One thousand two hundred and seventy four respondents were examined and each had Interpupillary distance measurements done using an automated refractor. The mean age of the study population was 41.18±20.12 years with 57.4% females. The mean IPD was 67.50±4.06 mm with a minimum value of 50mm and maximum of 84 mm. Most [75.51%] of the respondents had IPD measurements within the range of 65 mm to 74 mm. The mean IPD for males was 68.76±3.89 mm while females were 66.58±3.94 mm.
Conclusion: The mean IPD and its upper limit obtained in this study were higher than previously documented by other studies. Inter pupillary distance increased with age and was higher in males.
