BCVA best corrected visual acuity, logMAR logarithm of the minimal angle of resolution, FTMH full-thickness macular hole, FCS+ eyes with foveal crack sign; FCS− eyes without foveal crack sign, SD standard deviation, D diopters. Differences across the four groups were calculated using 1-way multivariate factorial ANOVA with post hoc Sidak’s test and the chi-square test according to the variables.
*Statistically significant.
