The effect of Alda-1 intervention on retinal histology in N-methyl-N-nitrosourea (MNU)-treated retinas. a, b Typical haematoxylin and eosin (HE) staining images of retinal sections of rats from all groups and plots of rows of the outer nuclear layer (ONL) 3 days after MNU administration. The number of rows of ONL in the Alda-1 intervention (A) group was lower than that of ONL in the normal (N) group but was higher than that of ONL in the model (M) group, and the differences were statistically significant (P < 0.05). ONL: outer nuclear layer; INL: inner nuclear layer; GCL: ganglion cell layer; Scale: 50 μm. N: the normal group; M: the model group; A: the Alda-1 intervention group. *, **: P < 0.05, P < 0.01 vs. the N group; #, ##: P < 0.05, P < 0.01 vs. the M group
