Right Eyes (N = 32)
Left Eyes (N = 32)
Interocular Comparison
Mean (± SD) 95% CI for Mean Mean (± SD) 95% CI for Mean
Rate of EZW constriction (μm/yr) 176.6 ± 130.1 129.7–223.5 173.1 ± 146.8 120.1–226.0 P = .8609
Rate of nasal ONL thinning (μm/yr) 2.71 ± 3.83 1.33–4.10 2.57 ± 5.21 0.70–4.45 P = .1619
Rate of temporal ONL thinning (μm/yr) 2.44 ± 4.01 0.99–3.88 2.48 ± 4.70 0.78–4.17 P = .8465
Average rate (nasal and temporal) of ONL thinning (μm/yr) 2.58 ± 2.85 1.55–3.60 2.52 ± 3.54 1.25–3.80 P = .6735
Intraocular comparison between nasal and temporal ONL thinning rates P = .9922 P = .4716

EZW = ellipsoid zone width; ONL = outer nuclear layer.

Positive values signify EZW constriction or ONL thinning. Two-tailed Wilcoxon signed rank test was used for statistical testing with significance level alpha set at 0.05.
