The distinguishing anthropometric features of the Saudi Arabian eyes

Purpose: Identifying the peri-ocular anthropometric measurements characteristic of Saudi Arabian eyes. Methods: A prospective, cohort, hospital-based study. Results: Measurements were made on 668 subjects (mean age 33.8 years; 58.7% female). The horizontal palpebral aperture was 30.1 ±2.9 mm (mean± SD), vertical palpebral aperture was 10.1 ± 0.85 mm, upper lid skin fold height was 3.6± 1.9 mm, upper lid crease height was 9.6± 0.8 mm, eyebrow height was 10.2 ± 2.7 mm, and intercanthal distance was 32 ± 2.7 mm. There was a statistically significant correlation between gender and eyebrow height (P = 0.001) and gender and horizontal palpebral aperture (P = 0.016), but no significant correlations were noted between any measurement and age. Conclusions: Saudi Arabian eyes are unique in exhibiting a higher upper lid skin fold, higher lid crease.
