Assessment of Interpupillary Distance in the Azerbaijan Society.

Introduction: To determine the normal distribution of interpupillary distance (IPD) in adult males and females of the Azerbaijani society and create a specific IPD database.

Materials And Methods: Subjects (641 males, 491 females) aged 18 to 85 years were investigated for anatomical IPD in this study. Eye examinations and measurements were performed. The subjects were divided into 2 main groups: male and female, and further divided into 4 groups according to the age range. Auto refractometer was used for IPD measurements (Topcon Auto Kerato-Refracto Tonometer TRK-2P, Tokyo, Japan).

Results: The mean age in the 18 to 85 age range was 39.1 ± 15.2 years. The mean IPD was 63.7 ± 3.5 mm (range 51-82). IPD values were higher in males (P < 0.001), and IPD values were found to be statistically significant (P < 0.001).

Discussion: Age, sex and ethnicity are all significant factors that influence IPD. IPD measurements are essential in surgical management, optical frames and lenses, forensic science and anthropological investigations.
