Representative Case in the Control Group. Serial fundus photographs (A: 2005; B: 2020) of the left eye of a 41-year-old man with baseline intraocular pressure (IOP) of 13 mmHg. Although the baseline vertical cup-to-disc ratio was 0.64, the eye did not show vertical cupping, violation of the ISNT rule, peripapillary atrophy or tilted disc configuration. There was no vessel narrowing or sclerotic changes, and the nasalization of central retinal vessel trunk was 49%. The baseline risk score was 0 (A). The subject did not show any retinal nerve fiber layer defects during the 15 years of follow-up (B).
