PFKM and axial length measurement: Glucose metabolic process related genes (UGP2(UDP-glucose pyrophosphorylase 2), GPI (glucose-6-phosphate isomerase), GPD1 (glycerol-3-phosphate dehydrogenase 1), PFKM (phosphofructokinase), TPI1 (triosephosphate isomerase 1), PKM2 (Pyruvate kinase isozyme type M2), PGM1 (Phosphoglucomutase 1)) expression in 35 AL group were lower than those in 22AL and 22PF group.
