Multiple-comparison Mann–Whitney U test with Bonferroni adjustment showed the best-corrected visual acuity (BCVA) distribution based on the etiologies of optic neuropathies. The BCVA of LHON patients was significantly lower than that of the other etiologies (all p < 0.05). Box-and-whisker plot showed that idiopathic optic neuritis (ON) and myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) were associated with relatively good BCVA and had a narrow distribution range, relative to the other optic neuropathies. The lower quartiles of toxic optic neuropathy and Leber's hereditary optic neuropathy (LHON) were located above the upper quartiles of idiopathic ON and MOGAD.
