People who use reusable contact lenses rather than disposable daily lenses are four times more likely to develop Acanthamoeba keratitis, a corneal infection that can cause sight loss.
The loss of blood flow autoregulation caused by diabetes is the result of the disruption of the TRPV2 protein. Even in the absence of diabetes, disrupted blood flow autoregulation causes damage closely resembling that seen in diabetic retinopathy.
Neurons in the midbrain receive strong, specific synaptic input from retinal ganglion cells, but only from a small number of the sensory neurons.
Determining the structure of vitronectin, a protein implicated in age-related macular degeneration and some neurodegenerative disorders, and using pressure to alter the protein shape may help in the development of new treatments for AMD.
A new study reports that a new gene therapy shows promise in treating dry age-related macular degeneration. The gene therapy, ophNdi1, directly targets mitochondrial function that is malfunctioning in AMD.
7-MX, a caffeine metabolite, may help to slow the progression of myopia or short-sightedness in children.
Alzheimer's disease disrupts some forms of visual memory by degrading a newly identified brain circuit that connects the primary visual cortex of each hemisphere.
During the embryonic stage, tactile information simultaneously activated the tactile and visual neural pathways. After birth, the pathways separate and reorganize to allow for individual processing of visual and tactile information.
Seven-month-old babies are able to detect whether a mosaic has a symmetrical structure, suggesting an automatic ability to extract structural patterns from complex images.
Researchers have developed a cornea implant from the collagen protein of pig skin. The implant restored the vision of 20 people with diseased corneas. The new implant could be a viable alternative to human cornea transplantation.
