One ophthalmologist said 30% optic nerve damage, one said he doesn't use percentages & another said it was lower. Why the different opinions?

One ophthalmologist said 30% optic nerve damage, one said he doesn't use percentages & another said it was lower. Why the different opinions?

Subjective exams: Examining the optic nerve requires the ophthalmologist to make a 'best guess' at the changes seen on examination. Because everyone has a unique appearance to their optic nerve, the assessment is rather subjective. Although there is imaging available (hrt, oct) none of these measures is precise. ...Read more
