Lycium barbarum polysaccharide extracts preserve retinal function and attenuate inner retinal neuronal damage in a mouse model of transient retinal ischaemia.

Daily consumption of Lycium barbarum polysaccharides effectively alleviated ischaemia-induced retinal dysfunction as well as reduced correlated neuronal death and glial activation. This prolonged effect could last at least 7 days. It suggested that Lycium barbarum polysaccharides might serve as a neuroprotective agent in ischaemic retinopathies.
