The optic nerve covering is elastic enough to allow a detectable enlargement in response to changes in intracranial pressure. The objective of the present study was to determine the optic nerve sheath diameter (ONSD) in normal Nigerian adults. ⋯ The normal reference values of ONSD measurements in adults were obtained. It showed no significant correlation with side (right and left), age, and sex. Furthermore, there is no significant correlation of ONSD with the body height and weight.
