Significant at 1%. CEXC: choroidal excavation; CT: choroidal thickness; DOLR: disrupted outer retinal layers; FT: foveal thinning; IRPED: irregular flat PED; IRPED-T: irregular flat PED with translucent (empty) sub-RPE space; IRPED-O: irregular flat PED with opaque (filled) sub-RPE space; RPED: regular smooth PED; SRD: subretinal deposits; SRPED-EF: sub-RPE deposits not related to irregular flat PED.
