Near-infrared and retinitis pigmentosa

  Rat and near-IR light

The red hue on this rat’s fur comes from a low-intensity near-infrared light source, under trial as a mechanism for stabilising the photoreceptors of the retina. The rat carries a mutant gene which causes degeneration of the photoreceptors, mimicking the blinding human diseases known as retinitis pigmentosa. The infrared radiation is absorbed by key metabolic enzymes in the photoreceptors, and restores their function, slowing degeneration. This is a promising non-invasive way of treating the human condition.
