Red light of the visual spectrum attenuates cell death in culture and retinal ganglion cell death <i>in situ</i>

Abstract

Low, non-toxic levels of red light focussed on the retina for a short period of time are sufficient to attenuate an insult of raised IOP to the rat retina. Since mitochondrial dysfunctions are thought to play a major role in ganglion cell death in glaucoma, we propose the potential use of red light therapy for the treatment of the disease.
