Optic nerve

Second cranial nerve atrophy

Optic nerve atrophy causes dimming of vision and reduction of the field of vision. The ability to see fine detail will also be lost. The pupil reaction to light will diminish and may eventually be completely lost.

Optic nerve atrophy can be readily detected on complete examination of the eyes. Seeking the cause may require a complete physical examination and specific tests.
