Objective To explore the trends in orbital fat volume in different age groups using magnetic resonance imaging （MRI）. Methods Investigative study. One hundred forty-four normal adults （18～72 year olds， 288 eyes） were divided into six groups according to age and sex： 18～35 years old， 36～50 years old， ≥51 years old with 24 cases in every group. The orbital fat volumes in all the above groups were examined by MRI scans and the measured data were standardized. ANOVA was used to analyze the changes in orbital fat volume in the different gender and age groups. Independent t test and Spearman correlation was also used. Results The orbital fat volume showed no significant differences among the three different male age groups （F=0.787， P>0.05） and female groups （F=1.183， P>0.05）. In addition， there was no significant difference in the orbital fat volume between the male and female groups （t=1.029， P>0.05）. There was no correlation between orbital fat volume and age （r=-0.087， P>0.05）. Conclusion There were no significant changes in orbital fat volume with increasing age and there were no differences in orbital fat volume between normal adult male and female groups.
