Abstract

PURPOSE
This study is to know a normal orbital volume of adult Koreans.
METHODS
We had taken 3-dimension orbital CT of 100 patients who had visited the department of ophthalmology and emergency room. Among them 30 patients who were reported to show abnormal orbital CT finding were excluded. Thereafter we measured orbital CT volume in eyes of 70 patients. We appointed inner sides of orbital wall in coronal plane image and reconstructed 3-dimension images by means of soft ware program(silhouette) in CT to measure the orbital volume.
RESULTS
Average of orbital volume was 24.5 mm 3(left orbital vol. 24.25 mm 3, right 24.75 mm 3), in males and 23.5 mm3(left 23.25 mm 3 , right 23.75 mm 3)in females. Difference between right orbit and left orbit was 2% and average of male orbital volume was bigger than female by 4%.
CONCLUSION
Adult Korean orbital volume measure was useful for differential diagnosis in orbital desease.
