Abstract:
PURPOSE: In this study we analyzed and compared the orbital anatomy in Korean and Caucasian subjects using computed tomography (CT) measurements. METHODS: Two observers performed a cross-sectional, retrospective analysis of 44 CT scans of subjects (22 Koreans, 22 Caucasians) with no appreciable orbital or globe disease. Ten length measurements and 3 angle measurements of various orbital aspects were obtained. Analysis was performed to determine if changes in these parameters were associated with race. RESULTS: Anterior medial interorbital length was 24.05 +/- 2.00 mm in Korean and 21.96 +/- 1.96 mm in Caucasian subjects. Anterior vertical orbital length was 34.19 +/- 1.67 mm in Korean and 35.03 +/- 1.18 mm in Caucasian subjects. The anterior medial interorbital length and anterior vertical orbital length (p < 0.05) were significantly different. Interorbital angle was 47.69degrees +/- 1.49degrees in Korean and 46.15degrees +/- 2.19degrees in Caucasian subjects; the difference was statistically significant (p < 0.05). CONCLUSIONS: Compared with Caucasians, the orbit of Korean subjects has a narrower orbital opening and longer interorbital distance. The present study regarding the anatomy of Korean and Caucasian orbits will assist physicians with the evaluation and treatment of orbital diseases.
