  4. There have been a mass of research documents showing that many visual functions deteriorate with age both for human beings and for animals. age - related visual function decline could not be completely attributed to optical and retinal changes. considerable visual impairments in the old might result from morphological ( such as cell loss, dendritic change and synaptic density decrease ) or functional ( such as weakened gaba inhibition ) degeneration of visual pathways. in this article we made preliminary studies on the mechnisam underlying visual function degradation by electrophysiological and morphological methods
