Why One Type of Cancer Therapy Improves Night Vision in People



Scientists have found that rhodopsin, the main visual pigment found in the rods of our retina, interacts with a light-sensitive compound called chlorin e6, an important component of photodynamic therapy.

Under the influence of light, the photosensitive visual pigment rhodopsin changes, and one of the intermediate products of its transformation is responsible for the occurrence of visual arousal. We don’t get enough light in the dark, but as it turned out, the mechanism described above could be triggered differently. Scientists have found that rhodopsin changes with infrared light and with the introduction of chlorin in the same way as with visible light. “This explains the increased visual acuity at night,” the researchers noted.

The authors of the scientific work carried out molecular modeling and understood what mechanism lies behind this.
