The bisretinoids of retinal pigment epithelium [PDF]
The retina exhibits an inherent autofluorescence that is imaged ophthalmoscopically as fundus autofluorescence. In clinical settings, fundus autofluorescence examination aids in the diagnosis and follow-up of many retinal disorders. Fundus autofluorescence originates from the complex mixture of bisretinoid fluorophores that are amassed by retinal ...

Schiff base deprotonation and structural changes in a mouse UV-sensitive cone visual pigment revealed by FTIR spectroscopy at 77 K [PDF]
UV-sensitive cone visual pigments are widespread among vertebrates, including birds, fish, and rodents such as mice, and play essential roles in non-primate vision.

Beyond SWS1 Cones: Canonical and Noncanonical Routes of Ultraviolet Sensitivity in the Avian Retina [PDF]
Ultraviolet sensitivity in birds is generally attributed to short-wavelength-sensitive type 1 single cones, but ultraviolet radiation may influence the retina through several additional pathways.

RPE65, an abundant membrane-associated protein present in the retinal pigment epithelium (RPE), is a vital retinoid isomerase necessary for regenerating 11-cis-retinaldehyde from all-trans retinol in the visual cycle.

The visual cycle refers to a series of biochemical reactions of retinoids in ocular tissues and supports the vision in vertebrates. The visual cycle regenerates visual pigments chromophore, 11-cis-retinal, and eliminates its toxic byproducts from the ...

The Physical Mechanism for Retinal Discrete Dark Noise: Thermal Activation or Cellular Ultraweak Photon Emission? [PDF]
For several decades the physical mechanism underlying discrete dark noise of photoreceptors in the eye has remained highly controversial and poorly understood.

Retinoids in the visual cycle: role of the retinal G protein-coupled receptor
Driven by the energy of a photon, the visual pigments in rod and cone photoreceptor cells isomerize 11-cis-retinal to the all-trans configuration.

Familial grouped pigmentation of the retinal pigment epithelium. [PDF]
Grouped pigmentation of the retinal pigment epithelium was found in a father and his son. They had a normal resting potential on the electro-oculogram, but the son had a lower normal light rise. We believe this is the first description of familial grouped pigmentation.
