Abstract

This work was designed to investigate some aspects of the ocular and orbital morphometric characteristics of the African giant rat (Cricetomys gambianus, Waterhouse). 16 African 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 studies were used to analyze the obtained 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) measurements 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 orbital 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.
