Measurement of Normal Optic Nerve for Adult Sudanese Using Computed Tomography

Abstract

This study was conducted to find out the mean optic nerve length and width in Sudanese population using CT. Number of 100 patients CT orbit and brain was performed for Sudanese patient there ages between 20–80 years old, were 49 males and 51 females. The result after data analysis was found the overall mean of optic nerve length was [5.0052±.43099] cm, and mean of optic nerve width [.3971±.10012] cm. with minimum length [4.00cm], and maximum length [6.23 cm].with minimum width [.23cm], and maximum width [.65 cm]. There is a correlation between Also there is correlation between the optic nerve length and the patient weight as weight increase the length increase. The optic nerve (length &width) slightly higher in males. There is no relation between optic nerve width &length and the tribe
