It begins at the optic disc (the \u201cblind spot\u201d) at the back of the eye and travels toward the brain\u2019s visual pathways. Clinicians use optic nerve findings to understand vision loss, eye pain, and changes in the visual field. It is commonly assessed in routine eye exams and in conditions such as glaucoma and optic neuritis."}
