Demographics of patients who developed ERM versus those who did not after peripheral retinal laser photocoagulation.

aData were presented as mean ± standard deviation.
bOther types of retinal degeneration include paving stone degeneration, reticular degeneration, cystoid degeneration, and frosted branch angiitis-like degeneration.
cHigh myopia refers to a refractive error of <−6.00 dioptres or an axial length of over 26 mm.
dData were analysed using an independent samples t-test for continuous variables and for using a chi-square test for categorical variables. P values of <0.05 were considered significant.
eAnti-inflammatory agents refer to nonsteroidal anti-inflammatory eye drops, including pranoprofen, diclofenac sodium, and bromfenac sodium.
