Abstract

<p style="TEXT-ALIGN: justify; MARGIN: 0in 0in 0pt" class="MsoNormal"><font face="Times New Roman"><span style="FONT-SIZE: 10pt">The normal range of intercanthal distance (ICD) and interpupillary distance (IPD) have only been reported in one minor ethnic group in <st1:country-region w:st="on"><st1:place w:st="on">Malaysia</st1:place></st1:country-region>, the KadazanDusun. The aim of this study was to establish the ICD and IPD in the three major ethnic stocks in <st1:country-region w:st="on"><st1:place w:st="on">Malaysia</st1:place></st1:country-region>, namely the Malays, Chinese and Indian. A total of 300 samples consisting of 50 adult males and 50 adult females of each ethnic stock were recruited from the campus of the <st1:place w:st="on"><st1:placetype w:st="on">University</st1:placetype> of <st1:placename w:st="on">Malaya</st1:placename></st1:place>. ICD was measured between the medial angles of the palpebral fissures and IPD was measured between the midpoint of the pupils at primary gaze. Measurements were done twice to the nearest 0.5 mm by one researcher using a caliper and metal ruler. A mean was taken out of these two measurements. If there were major discrepancies, a third reading was taken and the two closest measurements were accepted. In ICD measurement, all three group means were highly significantly different from each other. The widest space between the inner canthus was recorded in both sexes of the Chinese followed by the Malay and the narrowest space was noted in both sexes of the Indians.</span><span style="COLOR: black; FONT-SIZE: 10pt; mso-fareast-font-family: SimSun; mso-fareast-language: ZH-CN"> </span><span style="FONT-SIZE: 10pt">Gender variation is statistically significant where the males tend to have a wider intercanthal distance compared to females in all three ethnic groups</span><span style="COLOR: black; FONT-SIZE: 10pt; mso-fareast-font-family: SimSun; mso-fareast-language: ZH-CN">. T</span><span style="FONT-SIZE: 10pt">here was no significant difference between the mean IPD values between the three ethnics. However highly statistically significant difference (independent t-test, p &le; 0.001) was seen when comparing the two sexes, with the male generally had a wider IPD to the female in all the races. </span></font><span style="FONT-SIZE: 10pt"><font face="Times New Roman">This study suggests that the ICD and IPD in three major ethnics in <st1:country-region w:st="on"><st1:place w:st="on">Malaysia</st1:place></st1:country-region> are similar to those in the KadazanDusun, whites, black and mixed populations.<o:p></o:p></font></span></p> <p>&nbsp;</p>
