Eye patching is used in the orthoptic management [2] of children at risk of lazy eye (), especially strabismic or anisometropic [3] amblyopia. These conditions can cause visual suppression of areas of the dissimilar images [4] by the brain such as to avoid diplopia, resulting in a loss of visual acuity in the suppressed eye and in extreme cases in blindness in an otherwise functional eye.
Duchamp was not interested in what he called "retinal art"—art that was only visual—and sought other methods of expression. As an antidote to retinal art he began creating readymades in 1914, when the term was commonly used in the United States to describe manufactured items to distinguish them from handmade goods.
Optography is the process of viewing or retrieving an optogram, an image on the retina of the eye. A belief that the eye "recorded" the last image seen before death was widespread in the late 19th and early 20th centuries, and was a frequent plot device in fiction of the time, to the extent that police photographed the victims' eyes in several ...

Retinal hemorrhage (UK English: retinal haemorrhage) is a disorder of the eye in which bleeding occurs in the retina, the light sensitive tissue located on the back wall of the eye. [1] There are photoreceptor cells in the retina called rods and cones , which transduce light energy into nerve signals that can be processed by the brain to form ...

Negative afterimages are generated in the retina but may be modified like other retinal signals by neural adaptation of the retinal ganglion cells that carry signals from the retina of the eye to the rest of the brain. [3] Normally, any image is moved over the retina by small eye movements known as microsaccades before much adaptation can occur ...
