Abstract

Pupillary distance (PD), the horizontal distance between the centers of pupils in each eye, is very important parameter used due the preparation of prescription eye glasses. As well in Republic of Macedonia the PD is measured on potential user of prescription eye glasses before its making. Although regular every day practice, there is no any investigation related to PD of the population for the country. This fact motived as to perform small case study in order to obtained preliminary results for population PD for the country as well as to investigate its variation due to gender and age. The survey was done in Tetovo municipality (Republic of Macedonia) in 2013. A totally 98 participants (34 female and 64 male) in age from 9 to 90 were observed. The participant observation was included: the monocular pupillary distance near measurements for both eyes using millimeter ruler as well determination of PD in mm. The obtained results of PD were with in the range from 44 to 70mm with mean value of 63mm. The analysis of variance confirmed PD dependence of gender and age at 95% confidence level (ANCOVA, p<0.0001). The mean female PD value of (61±4) mm was lower than mean male PD value of (63±4) mm (Fisher LSD test, p=0.005). Due the linear regression analysis female PD and male PD dependence of age was modeled with linear function. Although the sign if I cant correlation between the quantities, the model was with relatively low coefficient of determination (R2=0.26) indicating possibility of another parameters influence on the PD results.
