| Patients (n = 57) |
Healthy Controls (n = 42) |
p value * | |
|---|---|---|---|
| RNFL thickness (μm) | 90.76 ± 10.68 | 99.96 ± 8.30 | <0.001 |
| GCC thickness (μm) | 75.85 ± 8.37 | 83.77 ± 5.91 | <0.001 |
| Vessel densities of SRCP (%) | 47.46 ± 2.03 | 48.67 ± 2.39 | 0.007 |
| Vessel densities of DRCP (%) | 48.77 ± 2.16 | 49.42 ± 2.18 | 0.141 |
