Retinal sensors convey stimuli through the optic tracts to the lateral geniculate bodies, where optic radiations continue to the visual cortex.

For example, backdated upgrades to Studio Pro included bug fixes, DRM removal for Steam users, and a fix to allow it to work properly on OS X Mavericks, and the iPad version was updated to include Retina support.
the inherence factors: Something the user is or does (e.g., fingerprint, retinal pattern, DNA sequence (there are assorted definitions of what is sufficient), signature, face, voice, unique bio-electric signals, or other biometric identifier).
The diving beetle Thermonectus marmoratus has recently become notable when it was discovered that its aquatic larval stage has been found to have used in its principal eyes two retinas and two distinct focal planes that are substantially separated, in the manner of bifocals to switch their vision from up-close to distance, for easy and efficient capture of their prey, mostly mosquito larvae.
Indocyanine green angiography can be used to assess the health of the retina in the affected area which can be useful in making a treatment decision.
Although Goethe did not propose any scientific reasoning behind his observations, in the late 1860s Bruecke and Donders first suggested that the chromostereoptic effect was due to accommodative awareness, given that ocular optics are not achromatic and red objects require more accommodation to be focused on the retina.
The retina of the eye is also a two-dimensional array of receptors but the brain is able to perceive the nature of three-dimensional objects by inference from indirect information (such as shading, foreshortening, binocular vision, etc.).
Tapetum lucidum, a layer of tissue in the eye that reflects visible light back through the retina
Cone dystrophy and achromatopsia, affecting the cones in the retina, and the anti-epileptic drug Trimethadione are typical causes.
In 2010 Glowicka and Flores collaborated again with the 15 minute performance piece RETINa inspired by the pioneering science of Étienne-Jules Marey that impacted cinema and the early documentary filmmaker Dziga Vertov.
Tests performed at the Complutense University of Madrid indicate that prolonged exposure to the shorter blue band spectrum LED lights may permanently damage the pigment epithelial cells of the retina.
He is the brother of John R. Hetling, a bioengineer who specializes in neural prosthesis of the neural retina.
The diagnosis included a pseudotumor of the retina, hyperplasia of retinal, ciliary, and iris pigment epithelium, hypoplasia and necrosis of the inner layer of the retina, cataract, and Phthisis bulbi.
Peter Wiedemann (born 23 October 1953 in Erlangen, Germany) is a German ophthalmologist, specialist in medical and surgical retina and head at the Department of Ophthalmology at the Leipzig University, Germany, since 1993.
Introduced by Franciscus Donders, the reduced eye model replaces the several refracting bodies of the eye (the cornea, lens, aqueous humor, and vitreous humor) are replaced by an ideal air/water interface surface that is located 20 mm from a model retina.
The procedure involved injecting rod precursors which formed an 'anatomically distinct and appropriately polarized outer nuclear layer' - two weeks later a retina had formed with restored connections and sight, proving that it was possible to reconstruct the entire light-sensitive layer.
Screenless computing systems can be divided into three groups: Visual Image, Retinal Direct, and Synaptic Interface.
The EyeWire project harnesses human computation in a game to trace neurons through images of a volume of retina obtained using SBEM.
Ora serrata The ora serrata is the serrated junction between the retina and the ciliary body
Looking directly at the photosphere of the Sun (the bright disk of the Sun itself), even for just a few seconds, can cause permanent damage to the retina of the eye, because of the intense visible and invisible radiation that the photosphere emits.
Inpatient and outpatient surgery serves patients requiring trauma, orthopedic, urological, ear/nose/throat, retina, cardiovascular, neurological, plastic and bariatric surgery.
Escalera became a wrestler before returning to boxing, and had a strong comeback as a Lightweight, beating men like Maurice Watkins and Gene Hatcher before suffering a detached retina and retiring from boxing for good in 1983.
Vitreous humour, a clear gel that fills the space between the lens and the retina in vertebrate eyes
