Refractive diopter is expressed as the mean (range) and the remaining data are expressed as the mean (standard deviation). *, one-way analysis of variance. Control group, patients with axial length <26.5 mm; PM group, PM patients with 26.5 mm < axial length <29.0 mm; high PM Group, PM patients with axial length >29.0 mm; VH, vitreous humor; PM, pathological myopia; PGDS, prostaglandin-H2 D-isomerase; GPX3, glutathione peroxidase 3; Nrf-2, nuclear factor erythroid 2-related factor.
