Fig 3. Correlations between clinical glaucoma measures in glaucoma patients with asymmetric optic nerve damage (n = 6).

(A) Vertical cup/disc ratio (vCD) predicts average retinal nerve fiber layer (RNFL) thickness (p = 3.20e-8, R² = 0.98). (B) vCD predicts visual field index (VFI) (p = 0.0027, R² = 0.64). (C) RNFL predicts VFI (p = 0.00060, R² = 0.76). Correlations within individual patients are indicated by each solid colored line, with closed points marking eyes with “advanced” glaucoma and open points marking eyes with “mild” glaucoma. A least-squares regression estimate is indicated by the dashed line.
