Values are presented as mean ± standard deviation.

ERM = epiretinal membrane; PVD = posterior vitreous detachment; MH = macular hole.

* Hemorrhage score means to score the degree of correlation between hemorrhage site and dimple site. If there was no hemorrhage on surgery, we excluded from score (4 in the ERM group and 2 in the MH group); †Kruskal-Wallis test; ‡Mann-Whitney test.
