Wei Cheong Ngeow, Adelina Akan, Jaclyn @ Marlyn George: The intercanthal andinterpupillary distances in Kadazan Dusun in Malaysia. Mal. J. Oral Maxillofax.Surg. 2006: 4: 8–11.

Abstract:The normal range of intercanthal distance (ICD) and interpupillarydistance (IPD) have not been recorded from Malaysians. The aim of this study was to establish the ICD and IPD in the Kadazan Dusun ethnic stock of Malaysia.A total of 140 samples consisting of 70 adult males and 70 adult females were recruited from an outpatient oral surgery clinic. ICD was measured between themedian angles of the palpebral fissures and IPD was measured between themidpoint of the pupils. Measurements were done twice to the nearest 0.5 mm bytwo different researchers using a caliper and metal ruler. A mean was taken outof these two measurements. It was found that ICD ranged from 27.0 mm to 38.0mm, with a mean of 33.0 (SD ± 2.3 mm). Generally, ICD was higher in male (mean33.3 ± 2.1 mm) than female (mean 32.6 ± 2.6 mm). IPD ranged from 53.0 mm to73.0 mm with a mean of 63.2 mm (SD ± 3.3 mm). Generally, IPD was higher inmale (mean 64.6 ± 3.2 mm) than female (mean 61.2 ± 3.0 mm). The measurementon male and female was only statistically significant for ICD (independent t-test;p< 0.05). Previous study on Caucasian and Black ICD indicates an average of 32± 3 mm and 33.9 ± 3.0 mm respectively and an average of 63 ± 3.0 mm forCaucasian’s IPD and 63.7 ± 3.7 mm for black’s IPD. This study suggests that theICD and IPD in KadazanDusun are within the range of that of the whites, blackand mixed populations.
