“ Glycine , when injected intravitreally, has an inhibitory action on the electroretinogram (ERG) of the rabbit resulting in a transient loss of the oscillatory potentials of the b-wave.”
“These changes are conspicuous especially 1-2 h after the injection and the cells become normal again within 24 h. It is concluded that glycine has an inhibitory action upon the rabbit ERG in vivo.”
