LbGP improves visual behaviors in MNU-injured mice.

(A) Motion trajectories of the mice in black-white transition tests of each group. (B) Duration of time spent in the black box for each group: Con group, n = 16; MNU group, n = 11; LbGP group, n = 10. (C) Illustration of the optomotor system. (D) Visual acuity (in cycles per degree, cpd) for each group (n = 6/group). LbGP treatment increased the time that photoreceptor-degenerative mice spent in the black box, as well as their visual acuity. Data are expressed as mean ± standard error of the mean; *P < 0.05, ***P < 0.001 (one-way analysis of variance followed by Tukey’s post hoc test). Con: C57BL/6J mice; LbGP: N-methyl-N-nitrosourea-injured mice with Lycium barbarum glycopeptide treatment; MNU: N-methyl-N-nitrosourea-injured mice without treatment.
