Palpebral fissure length in black and Hispanic children: correlation with head circumference.

Palpebral fissure length and head circumference were measured in 170 black and 170 Hispanic normal children aged 1 month to 16 years. Eye measurement values were compared with those for white children. It was found that black children have longer palpebral fissures than whites and in certain age groups, than Hispanics. A statistically significant correlation between palpebral fissure length and head circumference was established in black children.
