Objective: The aim was to obtain interpupillary distance (IPD) measurements of students in the Kumasi Metropolis. The study will provide a database for manufacturers of spectacle frames and optical equipment with Ghana as the target population. The IPD is a crucial measure that needs to be considered before frames can be selected for patients who have been prescribed with spectacle corrections. IPD data from other populations are unsuitable due to variations with age, sex and race.
Method: A cross-sectional study involving 500 students, aged 10 to 20 years and selected from Junior and Senior High Schools in the Kumasi Metropolis, was carried out. Interpupillary distances were measured using the pupillometer and the PD rule.
Results: Out of the 500 students, 290 (58%) were males. The study revealed that the distance and near IPD measured with pupillometer in students was 65.53 ± 3.348 mm and 61.60 ± 3.054 mm respectively. Furthermore, the IPD was 64.48 ± 3.429 mm and 62.01 ± 3.464 mm for distance and near, respectively, when measured with a PD rule.
Conclusion: IPD is affected by age, ethnicity and gender variations. The study will provide normal reference values of interpupillary distance in the Ghanaian population which will be useful to anthropometry, medicine, ophthalmic industry and primary eye care.
