The indicators were obtained by OCT and OCTA.RESULTS: Sub-foveal choroidal thickness(SFCT) in CSC was thicker compared to other groups(all P<0.05). SFCT in nv-AMD was thicker compared to thin-choroid PCV, but thinner compared with thick-choroid PCV(both P<0.05). As the ratio of thickness of Haller's layer to thickness of SFCT, which of thin-choroid PCV was significantly higher than CSC(P<0.001). Likewise, thick-choroid PCV had significantly higher ratio than nv-AMD(P=0.016) or CSC(P<0.001). There were differences among them in pigment epithelium detachment(PED). The whole-superficial retinal vessel density(RVD), deep RVD and choroidal capillary vessel density(CCVD) in CSC were significantly higher compared to other three groups, respectively(all P<0.05). The whole CCVD in nv-AMD was higher compared to thick-choroid PCV(P=0.032). Cross-sectional local angiographic form was 87.50%, 83.33%, 0 and 35.29% in thin-choroid PCV, thickchoroid PCV, nv-AMD and CSC, respectively. Cross-sectional diffuse angiographic form was 12.50%, 16.67%, 100% and 5.88% in thin-choroid PCV, thick-choroid PCV, nv-AMD and CSC, respectively.CONCLUSION: Combination of OCT and OCTA can effectively observe the significant alterations existed in PCV, CSC and nv-AMD, and there are distinctive differences among them. The pathogenesis is not exactly the same between PCV and nv-AMD, or PCV and CSC.展开更多
