Abstract:
Magnetic resonance imaging (MRI) is a spectroscopic imaging technique used
in medical to produce images of the human body. MRI is one of the safety diagnostic procedures for measurement of the optic nerve diameter.
This study was conducted to find out the mean optic nerve length and width in Adult Sudanese population using MRI. Number of 50 patients MRI orbit and brain was performed for Sudanese patient there ages between 20–80 years old, were 23 males and 27 females.
The result after data analysis was found the overall mean of optic nerve length was [4.7105±.43099] cm, and mean of optic nerve width [0.3972±0.09941] cm. with minimum length [3.8 cm], and maximum length [5.85 cm].with minimum width [0.28cm], and maximum width [0.56 cm].There is no difference between the dimensions of normal optic nerves in both eyes. There is correlations between the optic nerve length and the patient weight as weight increase the length increase, between the optic nerve length and the patient weight as weight increase the width increase, also there is correlation between length, width with age as age increase the length and width increase and the optic nerve (length &width) slightly higher in males.
