VHD = vitreous hyper-reflective dot; BCVA = best-corrected visual acuity; logMAR = the logarithm of the minimum angle of resolution; D = diopters; CRT = central subfield retinal thickness.
Results are expressed a mean ± standard deviation.
*Incidence of VHDs in total cases of stated condition.
P values were calculated with the chi-square analysis or Fisher exact test† for categorical variables and t-test for continuous variables.
