Eye diseases identified by how we watch TV

One of the leading causes of blindness worldwide could be detected by how our eyes respond to watching TV according to a new study from researchers at City University London. The researchers, who were funded by the UK charity Fight for Sight, found that they could identify diseases such as glaucoma by looking at maps… Read More


Major cause of blindness linked to calcium deposits in the eye

Microscopic spheres of calcium phosphate have been linked to the development of age-related macular degeneration (AMD), a major cause of blindness, by UCL-led research. AMD affects 1 in 5 people over 75, causing their vision to slowly deteriorate, but the cause of the most common form of the disease remains a mystery.* The ability to… Read More


Gene tied to profound vision loss discovered by scientists

An exhaustive hereditary analysis of a large Louisiana family with vision issues has uncovered a new gene tied to an incurable eye disorder called retinitis pigmentosa, according to an examination led by scientists at The University of Texas Health Science Center at Houston (UTHealth). It is a family of eye diseases that affects more than… Read More


Scientists study effects of sunlight to reduce number of nearsighted kids

Despite what many parents may think, kids who spend a lot of time reading or squinting at tiny electronic screens aren’t more likely to become nearsighted than kids who don’t. However, that risk is only reduced if the child spends plenty of quality time outside. The “outdoor effect” on nearsightedness, or myopia, is a longstanding… Read More


Laser treatment reverses effects of early age-related macular degeneration

A new technique reported in the February 2015 issue of The FASEB Journal suggests that during early stages, it might be possible to reverse age-related macular degeneration, a leading cause of blindness that is currently irreversible. The treatment involving a nanosecond laser may also have further implications for other eye diseases such as diabetic macular… Read More


Human eye can see ‘invisible’ infrared light

Any science textbook will tell you we can’t see infrared light. Like X-rays and radio waves, infrared light waves are outside the visual spectrum. But an international team of researchers co-led by scientists at Washington University School of Medicine in St. Louis has found that under certain conditions, the retina can sense infrared light after… Read More


Key discovery to preventing blindness, stroke devastation

Research led by Nicolas Bazan, MD, PhD, Boyd Professor, Ernest C. and Yvette C. Villere Chair of Retinal Degeneration Research, and Director of the Neuroscience Center of Excellence at LSU Health New Orleans, has discovered gene interactions that determine whether cells live or die in such conditions as age-related macular degeneration and ischemic stroke. These… Read More


New laser therapy helps slow macular degeneration

A new, low impact low energy laser treatment for patients with early age-related macular degeneration (AMD) has produced positive results by reducing indicators of the disease. Researchers from the University of Melbourne found unlike other laser treatments, this new faster laser did not result in damage to the retina, the sensitive light detecting tissue at… Read More


Nanotubes may restore sight to blind retinas

The aging process affects everything from cardiovascular function to memory to sexuality. Most worrisome for many, however, is the potential loss of eyesight due to retinal degeneration. New progress towards a prosthetic retina could help alleviate conditions that result from problems with this vital part of the eye. An encouraging new study published in Nano… Read More


Artificial retina could someday help restore vision

The loss of eyesight, often caused by retinal degeneration, is a life-altering health issue for many people, especially as they age. But a new development toward a prosthetic retina could help counter conditions that result from problems with this crucial part of the eye. Scientists published their research on a new device, which they tested… Read More
