Values are presented as mean ± standard deviation or number (%).

SF6 = sulfur hexafluoride; BCVA = best-corrected visual acuity; logMAR = logarithm of minimal angle of resolution; CMT = central macular thickness; IRT = inner retinal thickness; FSSD = foveal surface symmetry difference.

* Mann-Whitney test; chi square test.
