RVC = residual vitreous cortex; PVD = posterior vitreous detachment. Data displayed are either mean values with SDs for continuous variables or number and percentage for categorical variables in the absence and presence of RVC groups. Unmarked values are detected by the Kruskal–Wallis test, while those marked with by the chi-squared test.
