Quantitative analysis of macular vascular density and FAZ between retinitis pigmentosa patients and controls

RP patients Control group p-value*
SFAZ area (mm2) 0.39 ± 0.12 0.27 ± 0.12 <0.001†
DFAZ area (mm2) 0.41 ± 0.11 0.29 ± 0.13 <0.001†
FAZ circularity 0.66 ± 0.11 0.66 ± 0.15 0.280
SPD 0.38 ± 0.05 0.44 ± 0.04 <0.001†
DPD 0.35 ± 0.08 0.42 ± 0.03 <0.001†
SVD (mm-1) 16.88 ± 1.93 19.46 ± 0.70 <0.001†
DVD (mm-1) 13.51 ± 2.91 17.23 ± 1.41 <0.001†

Values are mean ± standard deviation. FAZ = foveal avascular zone; SFAZ = superficial FAZ; DFAZ = deep FAZ; SPD = superficial perfusion density; DPD = deep perfusion density; SVD = superficial vessel density; DVD = deep vessel den¬sity. * Mann-Whitney U tests with Bonferroni correction; † The signifi¬cance level cutoff of p ≤ 0.05.
