Glaucoma is an irreversible blinding eye disease characterized by progressive ganglion cell death. To date, IOP control has been almost the only clinical option for the treatment of POAG. However, visual field damage continues to progress after lowering IOP in most patients, suggesting the existence of more complex pathogenic mechanisms in glaucoma. Recently, a collaboration between Academician Yang Zhenglin and Professor Zhang Houbin of Sichuan Provincial People's Hospital affiliated with the University of Electronic Science and Technology revealed the important role of cholesterol metabolic homeostasis in the pathogenesis of glaucoma and rescued the ganglion cells of ABCA1 knockout mice after...

Scientists have discovered the world's largest known bacteria, reaching up to one centimetre (0.4-inches) in length. The species, called Thiomargarita magnifica, was discovered on sunken leaves in the waters of a mangrove swamp in Guadeloupe, Lesser Antilles in the Caribbean. It appears as thin white filaments like vermicelli pasta, and contains microscopic sulphur granules that scatter light, giving it a pearly gleam. The 'giant' organism is thousands of times larger than most bacteria and can therefore be seen by the naked eye. Thiomargarita magnifica 'challenges the prevailing view of bacterial cell size' and the assumption that microbes are only visible...

Disgraced Hollywood movie producer Harvey Weinstein is suing Fiat Chrysler Automobiles for $5 million plus interest over a 2019 crash in which he flipped a Jeep Wrangler while trying to avoid a deer. Lawyers for the now-incarcerated mogul filed the suit in New York Supreme Court on Tuesday, claiming the car company provided him with an 'unreasonably dangerous' car in exchange for product placement in one of his films. Then when he was driving in suburban Bedford, New York on August 17, 2019, his 2017 his 2017 Jeep Wrangler 'failed to decelerate despite Weinstein's application of the vehicle's braking system'...

The Age-Related Eye Disease Studies (AREDS and AREDS2) established that dietary supplements can slow progression of age-related macular degeneration (AMD), the most common cause of blindness in older Americans. In a new report, scientists analyzed 10 years of AREDS2 data. They show that the AREDS2 formula, which substituted antioxidants lutein and zeaxanthin for beta-carotene, not only reduces risk of lung cancer due to beta-carotene, but is also more effective at reducing risk of AMD progression, compared to the original formula. AMD is a degenerative disease of the retina, the light-sensitive tissue at the back of the eye. Progressive death of...

Since the first Covid-19 vaccine was authorised for use in the United Kingdom, and administered on the 8th December 2020, there have been hundreds of thousands of adverse reactions reported to the MHRA Yellow Card scheme. But there is one particular adverse reaction which is both concerning and strange, and the number of people suffering from it is increasing by the week – Blindness. The MHRA Yellow Card scheme analysis print for the Pfizer / BioNTech mRNA jab shows that since the first jab was administered on the 9th December 2020, and up to 6th April 2022, 163 people have...

Something happened recently that I believe may help some people. I have had many of these ocular migraines over the last two years. I kept a diary on their occurrences on my iPhone, because I wanted to have a trend line. Suddenly they stopped. Not one in the last eight months. The scare of actual migraine headaches (curse them!) has gone to near zero. I looked back at my medical records to see what happened. Please pass this information along to any person with this problem. The only thing that changed: I had a bad tooth extracted. It was on...

Texas congressman, former Navy SEAL, lost his right eye after being wounded by IED in AfghanistanRep. Dan Crenshaw, R-Texas, said he underwent emergency surgery Friday for a detached retina in his left eye and will be unable to see as he recovers."The surgery went well, but I will be effectively blind for about a month," Crenshaw said in a Twitter statement on Saturday.Crenshaw, a U.S. Navy SEAL veteran, lost his right eye during a deployment in Afghanistan when he was wounded by an improvised explosive device (IED) and wears a patch on that eye.Congressman Dan Crenshaw's post on Twitterhttps://twitter.com/RepDanCrenshaw/status/1380896286082265089 https://twitter.com/RepDanCrenshaw/status/1380896286082265089

Mitt Romney knocked unconscious, suffers black eye, more than a dozen stitches after fall Sen. Mitt Romney was knocked unconscious when he fell in Boston over the weekend, leaving him with “a lot of stitches” and a black eye. “I took a fall. Knocked me unconscious. But I’m doing better,” Romney told reporters on Capitol Hill Monday night. The Utah Republican said he was visiting his grandchildren when he got injured. “I went to CPAC, that was a problem,” he joked. Romney was not invited to the marquee event after receiving backlash over his vote to impeach President Donald Trump....

Damage to the retina is the leading cause of blindness in humans, affecting millions of people around the world. Unfortunately, the retina is one of the few tissues we humans can't grow back. Unlike us, other animals such as zebrafish are able to regenerate this tissue that's so crucial to our power of sight. We share 70 percent of our genes with these tiny little zebrafish, and scientists have just discovered some of the shared genes include the ones that grant zebrafish the ability to grow back their retinas. "Regeneration seems to be the default status, and the loss of...

Biden was in the middle of speaking when his eye appeared to fill with blood, and he seemed not to notice.

Former Vice President Joe Biden's left eye appeared to have a blood vessel burst while he was participating in CNN's town hall on climate change. Biden has long been plagued by health issues. In 1988, he suffered an aneurysm that burst and required him to undergo emergency surgery. The then-senator was so close to death that a Catholic priest began preparing to administer the sacrament of last rites. Months later, surgeons clipped a second aneurysm before it burst. Biden then took a seven-month leave from the Senate following the surgery. He’s described the operation as “they literally had to take...

One of the four albino anoles, alongside a non-modified example(Credit: University of Georgia) ============================================================ Although they're commonly known as brown anoles, there are now four Anolis sagrei lizards at a University of Georgia lab that are actually a pale pink color. They're albinos, and are the result of what is reportedly the world's first successful attempt at producing a genetically modified reptile. The research could have implications for human medicine. Lead scientist Douglas Menke chose brown anoles for the study because isolated populations of the lizards are known for independently evolving distinctive traits, on various islands in the Caribbean. Genetically...

New research shows that all blue-eyed people share a common ancestor. This person lived more than 6,000 years ago and carried a genetic mutation that has now spread across the world. The exact cause remains to be determined but scientists do know that eye color began to change long before recorded history began. The following is a transcript of the video. All blue-eyed people have one ancestor in common, born around 6,000-10,000 years ago. Blue eyes are caused by a gene mutation. For years, researchers had searched for it on the OCA2 gene. The OCA2 gene determines how much brown...

“Behold, He is coming with the clouds, and every eye will see Him, even those who pierced Him, and all tribes of the earth [land] will mourn because of Him.” This passage from Revelation 1:7 is often read by Christians and simply assumed to be a future event. (“Obviously, this hasn’t happened yet!”) Warning: the interpretation of this passage, read casually out of context, may not be as obvious as most Christians suppose. The context offers strong support for the preterist view, which is that this was fulfilled in AD 70 when Jesus “came in judgment” against apostate Israel. It...

Space does plenty of whacky things to astronauts' bodies, like deteriorating their muscle mass and making them on average 5 centimeters (2 inches) taller. But scientists have uncovered another, more subtle side effect — space is totally ruining astronauts' perfect eyesight. In fact, 80 percent of astronauts who come back from long-duration missions display symptoms of a mysterious eye condition that causes nearsightedness, Shayla Love reports for The Washington Post. While it's a myth that all astronauts have to have natural 20/20 vision (they're allowed to have corrective laser surgery) by the time they launch, their vision does need to...

Ulster University scientists have made a remarkable breakthrough which it is hoped could cure hereditary blindness. They have discovered a treatment that can target the gene that leads to corneal dystrophy—a condition that causes cloudy deposits on the cornea. […] Currently, those with corneal dystrophy face a lifetime of treatment and the only option for those who go blind is a corneal transplant from a donor eye, but this has risks and varying success rates. […] But the new treatment, developed by scientists at the University’s School of Biomedical Science, currently involves just one injection into the eye, which destroys...

Pupils' shape and size can reveal whether your kitten is a hunter or the hunted, research shows, Zee News reports. The study also said that species with pupils that are vertical slits are more likely to be ambush predators that are active both day and night. "For species that are active both night and day, like domestic cats, slit pupils provide the dynamic range needed to help them see in dim light yet not get blinded by the midday sun," said lead researcher Martin Banks, professor of optometry at University of California-Berkeley. The vertical slits of domestic cats and...

The leader of the Afghan Taliban, Mullah Mohammed Omar, has died, Afghan officials say, but the militant group has not commented on the claim. The reclusive leader died two to three years ago, Afghan government and intelligence sources said. No further details were released. A Taliban spokesman contacted by the BBC said the group would issue a statement shortly. There have been several reports of Mullah Omar’s death in the past. However, this is the first to be confirmed by top sources in the Afghan government. …
