The bottom picture is of the optic nerve in the right eye of this young patient. The top one is the left eye. The one on top is tilted because the optic nerve enters the eyeball obliquely. This will cause no harm to the patient, except she see’s 20/20 at distance with the right and 20/400 in the left. She is really near sighted in the left eye however but see’s 20/20 up close in that eye. If her eyes don’t change, she’ll never need bifocals when she’s past 45 years old.
