Abstract :
Purpose: To report normal interpupillary distance (IPD) values in different age groups
of an Iranian population.
Methods: This study was performed on 1,500 randomly selected subjects from 3,260
consecutive out-patients with refractive errors referred to Farabi Eye Hospital, Isfahan,
Iran over a period of two years (2008 to 2010). Measurement of refractive errors and IPD
for far distance were performed using an autorefractometer (RMA-3000 autorefractometer,
Topcon, Tokyo, Japan).
Results: Mean IPD in adult subjects was 61.1±3.5 mm in women and 63.6±3.9 mm in
men (p<0.001). Mean IPD increased 4.8 mm during the second decade, 1.7 mm during
the third decade, and 0.6 mm during the fourth and fifth decades of life.
Conclusion: The observed increase in IPD after the age of 30 years indicates that factors
other than skeletal growth may affect this parameter.
