*Statistically significant. SFCT: Subfoveal choroidal thickness; T1: choroidal thickness at 500 μm temporal to the fovea; T2: choroidal thickness at 1,000 μm temporal to the fovea; N1: choroidal thickness at 500 μm nasal to the fovea; N2: choroidal thickness at ,000 μm nasal to the fovea; CMT: central macular thickness.
