Abstract

The regulation of extracellular glutamate levels in the retina, under physiological and pathophysiological conditions, is essential for the prevention of excitotoxic neurodegeneration. Glial and neuronal high-affinity glutamate transporters (excitatory amino acid transporters, EAATs) facilitate the rapid removal of glutamate from the extracellular space, thereby terminating the excitatory signal and reducing the possibility of excitotoxic neuronal damage. Failure or reversal of these transport systems leads to raised levels of extracellular glutamate and contributes to the development of excitotoxic retinal degeneration.
