Farsighted Kids Have Trouble Paying Attention

Posted 5 days ago by Drugs.com

TUESDAY, Oct. 17, 2017 – Farsightedness affects young children's ability to pay attention in school, which could put them at risk of falling behind in the classroom, a new study suggests. "We knew from our previous work that preschool and kindergarten children with uncorrected farsightedness have decreased early literacy, and this new study shows that there are even more deficits in these children early on," said study author Marjean Taylor Kulp, a professor of optometry at Ohio State University. Between 4 and 14 percent of preschoolers have moderate farsightedness. That's when you have trouble seeing things that are close to you. The condition often goes undetected. The study included almost 250 preschoolers and kindergartners with moderate farsightedness and nearly 250 with normal vision. Researchers tested both groups and found that farsighted children were more likely to have ... Read more

FDA Panel Mulls Gene Therapy for Kids With Rare Eye Disease

Posted 10 days ago by Drugs.com

THURSDAY, Oct. 12, 2017 – A U.S. Food and Drug Administration advisory panel was poised on Thursday to recommend approval for a gene therapy that could grant the gift of sight to young people with a rare type of inherited vision loss. Replacing a nonworking gene with a new one is opening a new world for children and teens with the inherited retinal disease called Leber congenital amaurosis. "This is a gene therapy that can restore some vision to people who have very limited vision or no vision due to the mutation in the RPE65 gene, and as such, it's a great breakthrough," said Stephen Rose, chief research officer at the Foundation Fighting Blindness. For those who have already received the therapy, the treatment has been life-changing. Eleven-year-old Cole Carper got the treatment when he was 8, according to the Associated Press. Afterwards, "I looked up and said, 'What are those light ... Read more

After Deepwater Oil Cleanup in Gulf, Ill Effects Persist

Posted 20 days ago by Drugs.com

MONDAY, Oct. 2, 2017 – Workers exposed to dispersants while cleaning up a major oil spill in the Gulf of Mexico developed health symptoms, including wheeze and eye irritation, a new study says. Dispersants are chemicals used to break up oil slicks into smaller patches that can be degraded naturally or diluted by large volumes of water. U.S. National Institute of Environmental Health Sciences researchers are conducting a long-term follow-up study of the 2010 Deepwater Horizon oil spill. They found that cleanup workers exposed to dispersants were more likely to experience symptoms such as cough, wheeze, tightness in the chest, and burning in the eyes, nose, throat or lungs than those who weren't exposed to dispersants. Lead author Dale Sandler said the scientists were able to distinguish between health effects related to dispersants and those related to petroleum products in the spill. ... Read more

Brain Disconnects Spotted in Parkinson's Patients With Visual Hallucinations

Posted 28 Sep 2017 by Drugs.com

THURSDAY, Sept. 28, 2017 – Researchers say they've discovered a possible explanation for visual hallucinations in people with Parkinson's disease. The researchers conducted brain scans on 15 patients with visual hallucinations, 40 patients without visual hallucinations, and a control group of 15 people without Parkinson's disease. In all of the Parkinson's disease patients, numerous areas of the brain communicated less with the rest of the brain, compared to the control group, the Netherlands researchers noted. But patients with visual hallucinations had several additional brain areas with decreased connectivity with the rest of the brain, especially areas that are important in maintaining attention and processing of visual information. However, the study did not prove that this caused the hallucinations. The study was published online Sept. 27 in the journal Radiology. "Visual ... Read more

You Won't Believe What Lived Inside This Boy's Eye

Posted 20 Sep 2017 by Drugs.com

WEDNESDAY, Sept. 20, 2017 – For one unfortunate Mexican teenager, an unwanted tenant living in his eye led to what may be a permanent loss of vision, doctors report. As published Sept. 21 in The New England Journal of Medicine, an unnamed 17-year-old boy from a rural town in Mexico came to a hospital after suffering impaired vision and pain in his right eye for three weeks. According to ophthalmologists Drs. Pablo Guzman-Salas and Juan Serna-Ojeda, an examination showed an inflamed cornea, blood in the back of the eye, "multiple iris perforations" and other eye damage. The cause? "A flattened and mobile trematode [tiny flatworm] was seen moving freely" at the back of the eye, according to the doctors. The parasite was traveling – through holes it had made in the eye's iris – between the front and back portions of the eye. The doctors said the boy was given praziquantel, a drug used ... Read more

Doctors Eye the Danger From 'Nerf' Guns

Posted 19 Sep 2017 by Drugs.com

MONDAY, Sept. 18, 2017 – Nerf guns can be great fun for kids – until someone damages an eye, doctors warn. Nerf guns or "blasters" are hugely popular toys – used by kids and adults alike – that shoot a soft foam "dart" or "bullet." But a new report from emergency department doctors at one British hospital is raising concerns that the toy guns might not be as harmless as once thought. The report outlines three serious eye injuries from Nerf guns and "calls into consideration the need for protective eyewear with their use," according to Drs. Mukhtar Bizrah and Seema Verma of Moorfields Eye Hospital, NHS Foundation Trust, in London. One U.S.-based doctor agreed it might be time to re-examine the safety of these products. That's because people can now purchase harder – and potentially more dangerous – Nerf "bullets" online from manufacturers not tied to the toy's maker. "The seemingly ... Read more

Vision Problems Common in Babies Infected With Zika

Posted 14 Sep 2017 by Drugs.com

THURSDAY, Sept. 14, 2017 – When Zika infections strike in the womb, babies' eyes likely suffer, researchers say. Two studies of Brazilian infants with confirmed and suspected Zika virus infection in the womb found that all of them had vision problems. These problems included scarring, misalignment of the eyes, repetitive movement of the eye, and low vision. Of the 102 infants studied, about 40 percent had eye abnormalities and all had visual impairments, the study authors said. The findings were published online in the Journal of the American Association for Pediatric Ophthalmology and Strabismus. Because all infants had with visual impairment, these findings suggest "that the visual impairment is most likely related to the extensive damage to the central nervous system," said Dr. Liana Ventura, of HOPE Eye Hospital in Recife, Brazil. She was the lead investigator of one of the ... Read more

Diabetes Threatens Kidneys, Vision of Millions of Americans

Posted 13 Sep 2017 by Drugs.com

WEDNESDAY, Sept. 13, 2017 – Millions of Americans with type 2 diabetes and pre-diabetes are at risk for chronic kidney disease, and another 59,000 Americans, 40 and older, are at risk for diabetes-related blindness. That's the sobering conclusion of new research by investigators at the U.S. Centers for Disease Control and Prevention. The good news is that, in many cases, these complications can be reversed or their progression slowed, said Dr. Joel Zonszein. He's director of the Clinical Diabetes Center at Montefiore Medical Center in New York City. He wasn't involved with the new study. "When we talk about prevention, we are really talking not about disease prevention, but rather about sustaining good quality of life by delaying more complications," he said. "We can prevent complications by changes in lifestyle and the correct medications," Zonszein added. In fact, many patients with ... Read more

Did You Damage Your Eyes Viewing the Eclipse?

Posted 22 Aug 2017 by Drugs.com

TUESDAY, Aug. 22, 2017 – Millions across America watched the total or partial solar eclipse on Monday, but not everyone heeded eye-safety advice. "After the solar eclipse, we have already seen dozens of patients with concerns ranging from headaches to subjective blurry vision," noted Dr. Avnish Deobhakta. He's an ophthalmologist at the New York Eye and Ear Infirmary of Mount Sinai in New York City. Ideally, eclipse viewers shouldn't have taken any direct look at the sun. They should have used specially designed and filtered glasses instead. But in case that advice was forgotten, here's how to spot if you or a loved one got an unhealthy eyeful of the sun's rays. According to Deobhakta, "some of the symptoms include blurry vision, 'holes' or 'spots' in vision, light sensitivity, or infrequently, pain. You should also be concerned if you are experiencing persistent blurry vision, light ... Read more

Travel Tips for Contact Lens Wearers

Posted 20 Aug 2017 by Drugs.com

SATURDAY, Aug. 19, 2017 – Keep your eye on your contact lens regimen if you're traveling this summer. "Being prepared when traveling is key to eye safety," said Dr. Andrew Pucker, an associate professor at the University of Alabama at Birmingham School of Optometry. "While the vast majority of contact lens wearers believe they are compliant, up to 90 percent of patients fail to accurately complete at least one step of their care regimen," Pucker noted. Either they wear contact lenses for more days than recommended, keep them in overnight, expose their lens to tap water or fail to fully follow the cleaning instructions given to them by their optometrist, he said. Taking shortcuts in your eye care while traveling can exacerbate bad habits or create new dangers. Here, Pucker provides tips about contact lens safety for vacationers: Consider your destination: "Not all travel destinations ... Read more

6 Out of 7 Teens Slip Up on Contact Lens Guidelines: CDC

Posted 18 Aug 2017 by Drugs.com

THURSDAY, Aug. 17, 2017 – About 6 out of 7 U.S. teens with contact lenses use them improperly, upping their odds for serious eye infections, government health officials say. Surveying 12- to 17-year-old contact-lens wearers last year, researchers found 85 percent admit to at least one risky habit that could threaten their vision. These include sleeping, napping or swimming with their contacts in; reusing solution; rinsing lenses in tap water; or not replacing lenses and storage cases as recommended, according to a new U.S. Centers for Disease Control and Prevention report. About 3.6 million adolescents in the United States wear contact lenses, the CDC said. Outbreaks of serious eye infections are rare in this country. But they occur most often in people who don't take proper care of their contacts. Of teens under 18 who wear contacts, an estimated 3 million weren't completely following ... Read more

Successful Guide Dogs Come From 'Tough Love' Moms

Posted 7 Aug 2017 by Drugs.com

MONDAY, Aug. 7, 2017 – Newborn puppies whose mothers let them struggle a little are more likely to succeed in guide dog training than those with doting moms, a new study suggests. "It's remarkable," said study leader Emily Bray, who recently earned a Ph.D. in psychology at the University of Pennsylvania. "It seems that puppies need to learn how to deal with small challenges at this early age and, if they don't, it hurts them later." The study included 23 mothers and their 98 puppies at The Seeing Eye, an organization in Morristown, N.J., that breeds, raises and trains dogs to guide blind people. The researchers watched how mothers and pups interacted for the puppies' first five weeks of life. They took note of the mother's nursing position, how often she looked away from her pups, and how much time she spent nearby or licking and grooming them. Following up later, the researchers ...

As World's Population Ages, Blindness Rates Likely to Grow

Posted 3 Aug 2017 by Drugs.com

THURSDAY, Aug. 3, 2017 – More than 36 million people worldwide are blind, while 217 million more have moderate to severe vision loss, and experts now report that they expect those numbers to surge. By 2050, the researchers said, the number of blind people is likely to hit 115 million, with 588 million more having limited sight. The burden is greatest in developing nations, according to a study of data from 188 countries. "With the number of people with vision impairment accelerating, we must take action to increase our current treatment efforts at global, regional and country levels," said study lead author Rupert Bourne. He is associate director of the Vision and Eye Research Unit at Anglia Ruskin University in Great Britain. The study, published Aug. 2 in The Lancet Global Health journal, found southeast Asia has the most people who are blind. The study added that rates of blindness ... Read more

Vision Problems Can Harm Kids' Development, Grades

Posted 28 Jul 2017 by Drugs.com

FRIDAY, July 28, 2017 – Poor eyesight can make life harder for people at any age, but it can really take a toll on children's school performance and well-being, vision experts say. If left untreated, certain eye-related conditions can lead to developmental delays, learning issues and vision loss, warned specialists from the National Center for Children's Vision and Eye Health at Prevent Blindness. "The good news is that many vision problems in children can be treated successfully if detected early," Hugh Parry, president and CEO of Prevent Blindness, said in a news release from the organization. Prevent Blindness is the oldest nonprofit eye health and safety group in the United States. Vision problems affect more than one in 20 preschoolers and one-quarter of school-aged children, the eye experts said. The group urges parents and guardians to have children receive routine vision ... Read more
