New study on gene modulation may help prevent blindness
If scientists can use archaea — tiny organisms similar to bacteria — as a source of useful genes for humans, might it help prevent blindness one day?
Low-cost retinal scanner could help  prevent blindness worldwide
Biomedical engineers at Duke University have developed a low-cost, portable optical coherence tomography (OCT) scanner that promises to bring the vision-saving technology to underserved regions throughout the United States and abroad.
Smoking over 20 cigarettes a day can cause blindness
Heavy smokers also have reduced the ability to discriminate contrasts and colors compared with non-smokers.
Widespread errors in 'proofreading' cause inherited blindness
Mistakes in ‘proofreading’ the genetic code of retinal cells is the cause of a form of inherited blindness, retinitis pigmentosa (RP) caused by mutations in splicing factors.
Blue light from phone screens accelerates blindness
Scientists said they have found how blue light from smartphones, laptops and other digital devices damages vision and can speed up blindness.
Scientists advance stem cell therapy for a leading cause of blindness
Researchers made advances toward creating stem cell-derived retinal cells used to treat a leading cause of blindness, scientists at the National Eye Institute said.
Global blindness set to 'triple by 2050'
The number of blind people across the world is set to triple within the next four decades, researchers suggest.
Leaving contact lens in overnight could cause blindness
Contact lenses have vastly improved the options for those of poor sight. However, they can cause permanent vision loss if not worn properly.
New gene-delivery system can stop hereditary blindness, says study
According to a new study, a new gene-delivery system for an inherited form of blindness shows promise.
New hope for curing blindness
Scientists are on the brink of finding a cure for blindness after they successfully restored sight in mice.
New insight into cause of blindness
Age-related macular degeneration (AMD) is the worldwide leading cause of blindness in the elderly, and an international study has identified the number of genetic factors known to play a role in AMD.
Ebola survivors face possible blindness
Thousands of West Africans who were infected with the Ebola virus but survived it are suffering chronic conditions such as serious joint pain and eye inflammation that can lead to blindness, global health experts said.
New way of preventing diabetes-associated blindness
Reporting on their study with lab-grown human cells, researchers at The Johns Hopkins University and the University of Maryland say that blocking a second blood vessel growth protein, along with one that is already well-known, could offer a new way to treat and prevent a blinding eye disease caused by diabetes.
Potential therapy for acquired blindness
Hereditary blindness ― caused by a progressive degeneration of the light-sensing cells in the eye ― affects millions of people worldwide. Although the light-sensing cells are lost, cells in deeper layers of the retina, which normally cannot sense light, remain intact. A promising new therapeutic approach based on a technology termed "optogenetics" is to introduce light-sensing proteins into these surviving retinal cells, turning them into "replacement photoreceptors" and thereby restoring vision.
Brain sensory network not impaired with blindness: Study
In new research, scientists at the Hebrew University of Jerusalem and in Germany and the USA showed that the way in which the brain organizes its visual sense remains intact even in people who are blind from birth, and that at least the pattern of functional connectivity between the visual area and the topographical representation of space (up/down, left/right, etc.) can develop on its own without any actual visual experience.
