Basic Knowledge

The optic nerve extends from the posterior pole of the eye to the optic chiasm (Fig. 13.1). After this characteristic crossing, the fibers of the optic nerve travel as the optic tract to the lateral geniculate body. Depending on the shape of the skull, the optic nerve has a total length of 35- 55 mm. The nerve consists of:

❖ An intraocular portion.

❖ An intraorbital portion.

❖ An intracranial portion.
