Figure 4. Effect of MgAT and TAU on NMDA-induced changes on retinal morphology (20X). Pre, Co, and Post indicate that MgAT/TAU were injected 24 h before, simultaneously, or 24 h after intravitreal administration of NMDA, respectively. Scale bar represents 50 μm. NMDA: N-methyl-D-aspartic acid, MgAT: Magnesium acetyl taurate, TAU: Taurine, GCL: Ganglion cell layer, IPL: Inner plexiform layer; IR: Inner retina.
