Slowing the visual cycle reduces the availability of vitamin A derivatives (11-cis- and all-trans-retinal) to form precursors of A2E and related compounds.
Light acts on rhodopsin triggers, the well-known visual transduction cascade, but can also induce cell damage and death through phototoxic mechanisms [16]; reactive oxygen and nitrogen species are generated when light affecting the retinoids leads to the ionization of biomolecules and release of all-trans-retinal. Afterwards, the excitation of all-trans-retinal generates oxygen enhancement and causes photooxidative damage [17].
