Did You Damage Your Eyes Viewing the Eclipse?

Posted 1 day 2 hours ago 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 3 days ago 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 6 days ago 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 16 days ago 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

Generic Eye Drops for Seniors Could Save Millions of Dollars a Year

Posted 28 Jul 2017 by Drugs.com

FRIDAY, July 28, 2017 – Prescribing generic drugs for seniors' eye problems could save the U.S. government hundreds of millions of dollars a year, a new study suggests. Conditions like glaucoma and dry eye that require daily eye drops are common in old age. University of Michigan researchers report that eye doctors caring for seniors prescribe brand-name medications in more than three-quarters of cases, compared to one-third of cases among nearly all other specialties. "Lawmakers are currently looking for ways to reduce federal spending for health care, and policies that favor generics over brand medications or allow Medicare to negotiate drug prices may lead to cost savings," said study senior author Lindsey De Lott, of the university's Kellogg Eye Center. "Using a brand medication for a single patient may not seem like a big deal, but ultimately, these higher costs are paid by all of ... Read more

Laser Therapy Shows Promise Against Eye 'Floaters'

Posted 20 Jul 2017 by Drugs.com

THURSDAY, July 20, 2017 – A laser treatment can reduce spots in people's vision known as "floaters," a new study finds. "Floaters often arise as the vitreous – a gel-like substance that fills the eye – contracts and pulls away from the back of the eye," explained ophthalmologist Dr. Naomi Goldberg, who reviewed the new research. She works at the Manhattan Eye, Ear and Throat Hospital in New York City. Floaters become more common with age, and although some people simply get used to them, others are bothered by them or their vision is impaired. The new research was led by Dr. Chirag Shah and Dr. Jeffrey Heier of Ophthalmic Consultants of Boston. They explained that, currently, there are three management options for floaters: patient education and observation; surgery; and a laser procedure known as YAG vitreolysis. However, Shah and Heier said there are few published studies on the ... Read more

Many People Can't Spot a Faked Photo, Study Finds

Posted 18 Jul 2017 by Drugs.com

TUESDAY, July 18, 2017 – In an era when the phrase "fake news" is on many lips, a new study suggests that people are terrible at detecting whether photos have been manipulated to misrepresent reality. "Our findings suggest that people have an extremely limited ability to distinguish between real and fake images," said study lead author Sophie Nightingale. She's a graduate student at the University of Warwick in England. "In fact, people perform close to chance when asked if a photo has been manipulated. This suggests that we can be easily fooled by fraudulent online news," Nightingale said. Photo manipulation is hardly new. Photographers and others have faked photos since the early days of photography. For example, fraudulent photos of ghosts and fairies became a fad in the late 19th century. But computer digital technology has taken photo manipulation to a higher level. "It's never ... Read more

Impaired Eyesight May Be First Sign of Zika Damage in Babies

Posted 17 Jul 2017 by Drugs.com

MONDAY, July 17, 2017 – Infants exposed to the Zika virus in the womb should have their eyes examined for possible virus-related abnormalities, according to a new report. "All infants with potential Zika virus exposure should undergo screening eye examinations regardless of [central nervous system] abnormalities, timing of maternal infection during pregnancy, or laboratory confirmation," said Dr. Andrea Zin and colleagues. Zin is with the National Institute of Women's Health in Rio de Janeiro, Brazil. In some cases, evidence of Zika infection may only show up in the eyes, the study found. The results were published July 17 in the journal JAMA Pediatrics. "Eye abnormalities may be the only initial finding in congenital Zika virus infection," Zin said in a journal news release. Zika, a mosquito-borne virus, usually causes only mild symptoms in healthy adults. But fetal exposure during ... Read more

Early Parkinson's May Prompt Vision Problems

Posted 11 Jul 2017 by Drugs.com

TUESDAY, July 11, 2017 – Changes in vision may be an early sign of Parkinson's disease, researchers report. The neurodegenerative condition is caused by the loss of neurons in several brain structures, resulting in tremors, rigidity or stiffness, along with impaired balance and coordination, the Italian researchers explained. But, "although Parkinson's disease is primarily considered a motor disorder, several studies have shown non-motor symptoms are common across all stages of the disease," said lead researcher Dr. Alessandro Arrigo. He is a resident in ophthalmology at the University Vita-Salute San Raffaele of Milan. "However, these symptoms are often undiagnosed because patients are unaware of the link to the disease and, as a result, they may be undertreated," Arrigo added. Non-motor symptoms in Parkinson's disease patients include visual changes, such as an inability to perceive ... Read more

Soft Contact Lenses Safe for Kids and Teens, Review Finds

Posted 5 Jul 2017 by Drugs.com

WEDNESDAY, July 5, 2017 – Soft contact lenses are as safe for children and teens as they are for adults, a new review finds. "In the past decade, there has been increasing interest in fitting children with contact lenses," said review author Mark Bullimore, an adjunct professor at the University of Houston College of Optometry. He reviewed nine studies that included 7- to 19-year-olds who use soft contact lenses, to gauge the risk of corneal inflammation and infection. Called "corneal infiltrative events," these are usually mild, but about 5 percent involve a serious infection called microbial keratitis. Bullimore found a relatively low rate of these corneal infiltrative events among youths, with one large study finding the rate of events in younger children (8 to 12) much lower than in teens aged 13 to 17. The review also found that microbial keratitis was uncommon, with one study ... Read more

Eye Docs Debunk 5 Fireworks Myths

Posted 2 Jul 2017 by Drugs.com

SUNDAY, July 2, 2017 – Firecrackers, sparklers and bottle rockets may seem harmless enough, but there's really no such thing as safe fireworks for consumers, eye doctors warn. Each year, about 10,000 fireworks-related injuries are treated at U.S. emergency departments. Most of those cases involve children, including many who suffer eye injuries, according to the American Academy of Ophthalmology (AAO). Most of the injuries are caused by legal fireworks that parents buy for their children, such as sparklers, firecrackers and Roman candles, according to the AAO. The group debunks five top fireworks myths. Myth 1. Sparklers are safe for young children. False. Sparklers burn at 1,800 degrees – that's hot enough to melt some metals. Sparklers are responsible for most fireworks-related injuries among children age 5 and younger. Myth 2. It's safe to watch nearby fireworks if you don't light ... Read more

Gene Sequencing May Reveal Risks for Rare Diseases

Posted 26 Jun 2017 by Drugs.com

MONDAY, June 26, 2017 – "Genome sequencing" of healthy people reveals that some are at risk for rare genetic diseases, a new study shows. And doctors need to be sensitive when revealing that information, the researchers said. "Sequencing healthy individuals will inevitably reveal new findings for that individual, only some of which will have actual health implications," said study lead author Dr. Jason Vassy. He's a clinician investigator at Brigham and Women's Hospital in Boston. Vassy and his colleagues said they found "reassuring evidence" that doctors can be trained to manage their patients' sequencing results appropriately. Moreover, "patients who receive their results are not likely to experience anxiety connected to those results," Vassy said in a hospital news release. Whole genome sequencing entails analysis of the 3 billion pairs of letters in someone's DNA. Scientists ... Read more

Surf's Up! How to Plan for a Safe Beach Vacation

Posted 25 Jun 2017 by Drugs.com

SATURDAY, June 24, 2017 – Heading to the beach this summer? Make safety part of your vacation planning. Sun protection belongs at the top of your packing list. Must-haves include sunscreen, sunglasses, protective clothing and a hat, the U.S. Food and Drug Administration says. Here are some of the agency's other recommendations: Don't use tanning beds to pre-tan before a beach vacation. The lamps emit harmful ultraviolet rays that can damage your skin. Also, be aware that spray tans and bronzers do not protect against UV rays. Make a list of medications you need to take, and get enough to last the trip. Keep your medicines with you when traveling. Also, carry a detailed list of what medicines you take and have your health care provider's contact information in case you need medical care while you're away. If you wear contact lenses, pack enough for the entire vacation. Don't forget to ... Read more
