Background: Exophthalmometry and palpebral dimensions measurements are important in ophthalmic, as well as facial reconstructive surgery practice and the range of normal values vary among different races and age groups.
Objective: To establish a set of exophthalmometric values and palpebral dimensions in a healthy Nigerian population of older children and young adults.
Methods: A descriptive cross sectional school survey was conducted among secondary school students aged 10 to 18 years in a Local Government Area, South-Western Nigeria. Exophthalmometry value and palpebral dimensions were measured using Hertel exophthalmometer and a non-stretchable transparent plastic millimeter ruler respectively.
Results: The mean exophthalmometric value was 15.95 ± 1.10 mm in both eyes, (right eye, 15.88 ± 1.01; left eye, 16.02 ± 1.04, t = -9.146, p <0.001) and it increased with age (r = 0.725, p < 0.001). In the right eye, the mean palpebral fissure height was 10.60 ± 0.71 mm, palpebral fissure width was 31.10 ± 1.18 mm, medial canthal distance was 8.8 ± 0.78 mm, lateral canthal distance was 10.8 ± 0.75 mm, and margin reflex distance-1 was 3.5 ± 0.50 mm. In the left eye, the mean palpebral fissure height was 10.50 ± 0.72 mm, palpebral fissure width was 31.20 ± 1.12 mm, medial canthal distance was 8.7 ± 0.79 mm, lateral canthal distance was 10.8 ± 0.77 mm and margin reflex distance-1 was 3.5 ± 0.50 mm. A statistically significant difference (p=0.014) was noted only in the palpebral fissure width between the two eyes.
Conclusion: This survey has established normative values for exophthalmometry and palpebral dimensions among 10- to 18-year-old Nigerians in our locality which can be compared with other parts of the country.

Résumé
Contexte: Les mesuresde dimensions de l’exophtalmométrie et palpébrale sont importantes dans l’ophtalmie ainsi que lapratique de la chirurgie reconstructive faciale, et la gamme des valeurs normales varie selon les races et les groupes d’âge.
Objectif: Pour établir un ensemble de valeurs exophtalmométriques et de dimensions palpébrales dans une population nigériane saine d’enfants âgés et de jeunes adultes.
Méthodes: Une enquête transversaledescriptive sur les écoles a été réalisée chez des élèves du cycle secondaire âgés de 10 à 18 ans dans une commune, sud-ouest du Nigeria. La valeur de l’exophtalmométrie et les dimensions palpébrales ont été mesurées à l’aide de l’exophtalmètre d’Hertel et d’une règle millimétrique en plastique transparent non extensible respectivement.
Résultats: La valeurmoyenne exophtalmométrique était de 15,95 ± 1,10 mm dans les deux yeux, (oeil droit 15,88 ± 1,01 ; œil gauche 16,02 ± 1,04, t = -9,146, p <0,001) et elle a augmentée avec l’âge (r = 0,725 p <0,001). Dans l’œil droit, la taille moyenne de la fissure palpébrale était de 10,60 ± 0,71 mm, la largeur de la fissurepalpébrale était de 31,10 ± 1,18 mm, la distancecanthale médiale était de 8,8 ± 0,78 mm, la distance canthale latérale était de 10,8 ± 0,75 mm et la distance réflexe marginale-1 était 3,5 ± 0,50mm. Dans l’œil gauche, la taille moyenne de la fissure palpébrale était de 10,50 ± 0,72 mm, la largeur de la fissure palpébrale était de 31,20 ± 1,12 mm, la distance canthale médiale était de 8,7 ± 0,79 mm, la distance canthale latérale était de 10,8 ± 0,77 mm et la distance réflexe marginale -1 était de 3,5 ± 0,50mm. Une différence statistiquement significative (p = 0,014) n’a été notée que dans la largeur de la fissure palpébrale entre les deux yeux.
Conclusion: Ce sondage a établi des valeurs normatives pour l’exophtalmométrie et les dimensions palpébrales parmi les nigérians de 10 à 18 ans dans notre localité ce qui peut être comparés avec d’autres régions du pays.
