Forty-five females with mean age of 36 years (5-80 years) and 55 males with mean age of 39 years (3-68 years) participated in the study. We divided subjects into 6 groups according to decades. We measured the palpebral fissure length (PFL), the distance between the pupil center and the upper eyelid (PC-UE) and lower eyelid margin (PC-LE), the eyebrow height (EH), the eye crease height (ECH) and the distance from the reference line to the pupil center (RL-PC), using a reference line through the medial canthus and vertical line through the pupil center of the frontal slides.RESULTS: The measurements of PFL were between 23.5 mm and 29 mm in females, 24.8 mm and 29.1 mm in males and showed a gradual decrease with age. The PC-UE, PC-LE, ECH and RL-PC remained stable throughout life and were identical for both gender. However, EH ranging from 10.7 - 12 mm in females and 6.5 - 11 mm in males appeared to have a significant association with gender, which was higher in females than males, but was not effected with age.CONCLUSION: These results demonstrate the importance of providing a normal anatomic relationship that relates to the patient{\textquoteright}s age and gender.}, issn = {0379-5284}, URL = {https://smj.org.sa/content/26/10/1535}, eprint = {https://smj.org.sa/content/26/10/1535.full.pdf}, journal = {Saudi Medical Journal} }
