Choroidal morphology characteristics between PS and Group 1. a Choroidal thickness at each quadrant. Ch, central of subfovea horizontally; Cv, central of subfovea vertically; N, nasal; T, temporal; S, superior; I, inferior. b Choroidal vascular index at each sector. Ch, central of the fovea horizontally; N1, nasal parafovea; N2, nasal perifovea; T1, temporal parafovea; T2, temporal perifovea; Cv, central of the fovea vertically; I1, inferior parafovea; I2, inferior perifovea; S1, superior parafovea; S2, superior perifovea. *P < 0.05, **P < 0.01 and ***P < 0.001 delegate significant difference between the two groups
