    This work was designed to investi gate some aspects of the ocular and orbital morphometric characteristics of the African giant rat (Cricetomys gambianus, Waterhouse). 16 Afri can giant rats consisting of 8 males and 8 female rats were euthanized; the eyeballs were enucleated and their skulls macerated to give 18 morphometric parameters. Student t-test and Pearson’s correlation stu dies were used to analyze the ob tained values. Correlation studies showed significance in the left orbit al height as correlated against the right orbital index. The eyeball weight for right and left eyeballs were 0.16 g and 0.15 g.The mean eyeball circumference (antero- posterior and medio-lateral) mea surements were 2.23 ± 0.01cm and 2.02 ± 0.06 cm for the left and 2.06 ± 0.04 cm and 2.13 ± 0.03 cm for the right eyeball respectively. The mean right orbital length, right orbit al height, left orbital height and the intercanthi width were 2.09 ± 0.02 cm, 1.21 ± 0.03 cm, 1.23 ± 0.03 cm and 0.93± 0.03 cm respectively but were all statistically higher (p< 0.05) in males than females exhibiting sexual dimorphism.
