In the eye, the retinal primordium induces the formation of a complex image-forming optic apparatus, and the epithalamic pineal vesicle lacks this property; instead, it is associated with a transparent or translucent window in the skull. Light sensitivity in both cases is mediated by visual ...
The photoreceptor outer segment is a modified primary non-motile cilium of which the connecting cilium is a part (the “transition zone” of a conventional cilium). From:Progress in Retinal and Eye Research,2022 About this page Set alert ...

colour vision for other more vital kinds of information processing such as improving quantum catch and possibly also contrast transfer or movement detection.
Photoreceptor degeneration in the eyes of an amphisbaenian in response to constant light or constant darknessEye morphology and behavioral responses were studied in Bipes biporus (Cope) exposed to normal photoperiods, constant light, and constant darkness. Control animals had retinas with a reduced ...
“eye spots”, “pit eyes” and “ocelli”, are present in a wide variety of invertebrates. They can exist singly or in various numbers to provide the primary visual apparatus for an animal. Alternatively, they may be found in conjunction with a set of larger image-forming complex eyes. ...

To date, only studies of photoreceptor number in donor eyes and visual function in living subjects have directly addressed differences between rod and cone biology in the same aged or ARM eyes. The anatomical macula is a 6 mm diameter eye centred on the fovea.8 The macula contains two ...
Histological study of photoreceptor cells in retina of Rana ridibunda ridibunda pallas eye and the effect of exposure to some wavelengths of visible light The exposure to green and yellow light also incluced injuries in the pigment epithelium layer and photoreceptor cells layer, some similar to that...
Most detailed vision is obtained on the part of the image that is projected on the fovea. When the eye scans a scene, it projects the region of greatest interest onto the fovea. The region around the fovea contains both cones and rods. The structure of the retina becomes more coarse away...
