Farsighted Kids Have Trouble Paying Attention

Posted 4 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

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

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

Scientists Shed Light on Possible Cause of Nearsightedness

Posted 22 Feb 2017 by Drugs.com

TUESDAY, Feb. 21, 2017 – Whether you're nearsighted or not might come down to one particular type of cell in your retina, a new mouse study suggests. Researchers from Northwestern University's Feinberg School of Medicine in Chicago report that this cell is highly sensitive to light and controls how the eye develops. If it malfunctions and tells the eye to grow for too long, images don't get focused in the retina as they should be, the researchers said. "The eye needs to stop growing at precisely the right time during childhood," said lead investigator Greg Schwartz, an assistant professor of ophthalmology. "But for years no one knew what cell carried the signal," he explained in a university news release. "We potentially found the key missing link, which is the cell that actually does that task and the neural circuit that enables this important visual function." The study was conducted ... Read more

Eye-Opening Research on Astronauts' Vision Problems

Posted 6 Feb 2017 by Drugs.com

FRIDAY, Feb. 3, 2017 – Vision deterioration is a major problem for astronauts who spend extended periods of time in space. Now researchers have identified the likely cause of the problem and a possible way to prevent it. According to researchers at UT Southwestern Medical Center at Dallas, the probable cause is the lack of a day-night cycle in intracranial pressure – pressure around the brain. The new study showed that intracranial pressure in zero-gravity conditions, such as exists in space, is greater than when people stand or sit on Earth, but lower than when people sleep. It might be possible to prevent the problem by using a vacuum device to lower pressure for part of each day, the investigators suggested. "Astronauts are basically supine [lying face upward] the entire time they are in space. The idea is that the astronauts would wear negative pressure clothing or a negative ... Read more

'Halo' Effect Common After Lasik Eye Surgery

Posted 2 Dec 2016 by Drugs.com

FRIDAY, Dec. 2, 2016 – Nine out of 10 Lasik laser eye surgery patients report satisfaction afterwards. But a sizable percentage experience new visual disturbances – like seeing halos around lights – up to six months after the procedure, a new study finds. "While Lasik has long since been proven safe and effective over decades of use, a small but significant subset of patients report post-operative effects including glare, halos and other vision symptoms, as well as dry eyes," said Dr. Christopher Starr. He's an associate professor of ophthalmology at Weill Cornell Medicine/NewYork-Presbyterian Hospital in New York City. "These effects typically resolve over time, either during the healing process, which can take up to 12 months, or with additional treatments if needed," said Starr, who wasn't involved in the new study. Of hundreds of patients surveyed, fewer than 1 percent said any ... Read more

Can Extra Time Outdoors When Young Reduce Nearsightedness?

Posted 2 Dec 2016 by Drugs.com

THURSDAY, Dec. 1, 2016 – Spending more time outside early in life may offer some protection against nearsightedness, a new study suggests. The European study authors suspect that additional exposure to the sun's ultraviolet B (UVB) rays may play a role in reducing nearsightedness – the inability to see clearly at a distance, also known as myopia. "We found that higher annual lifetime UVB exposure, directly related to time outdoors and sunlight exposure, was associated with reduced odds of myopia," the study authors wrote. "Exposure to UVB between ages 14 and 29 years was associated with the highest reduction in odds of adult myopia," they added. The findings don't "add a lot to the picture" of current research that links nearsightedness to time outdoors, said Ian Morgan, a vision researcher and visiting fellow at Australian National University. He was not involved with the study. ... Read more

Some Primates Have Vision Troubles as They Age

Posted 8 Nov 2016 by Drugs.com

TUESDAY, Nov. 8, 2016 – Just like humans, some primates start having difficulty seeing things up close as they age. Researchers reviewed photos of 14 wild bonobos as they groomed each other. The primates were between 11 and 45 years old. The older they were, the longer they stretched their arms as they groomed, the study reported. The findings were published Nov. 7 in the journal Current Biology. "We found that wild bonobos showed the symptoms of long-sightedness around 40 years old," study author Heungjin Ryu, from the Primate Research Institute at Kyoto University in Japan, said in a journal news release. "We were surprised that the pattern found in bonobos is strikingly similar to the pattern of modern humans," he said. There have also been anecdotal reports of similar behavior in chimpanzees. Long-sightedness might hinder the social lives of older bonobos and could explain why ... Read more

Undiagnosed Eye Problems Pose Risks for Migrant Farm Workers

Posted 10 Oct 2016 by Drugs.com

MONDAY, Oct. 10, 2016 – Vision problems are common among migrant farm workers, but many never get eye exams, a new study shows. Researchers studied 289 Hispanic migrant farm workers in North Carolina who did not use eyeglasses. About three-quarters of them had never had an eye exam. Of those, 70 percent said they never considered having one, and 14 percent cited cost or lack of insurance. Vision tests found that about 2 percent of the farm workers had moderate to severe problems with distance vision. About 7 percent had impaired near vision. Predictably, older workers had more problems with their eyesight. Twenty-one percent of those 40 and older had moderately to severely impaired near vision. About 5 percent had distance vision problems. Among younger workers, 0.5 percent had trouble with either near or distance vision. "Vision examinations indicate that a number of farm workers ...

Laser Device Approved for Nearsightedness

Posted 14 Sep 2016 by Drugs.com

WEDNESDAY, Sept. 14, 2016 – The VisuMax Femtosecond Laser has been approved by the U.S. Food and Drug Administration to treat nearsightedness in candidates 22 and older. Nearsightedness, medically called myopia, is present when a person can see close objects clearly, but not objects farther away. Common causes include a misshapen cornea or excess length of the eyeball, the FDA said in a news release. The procedure to permanently reshape the cornea is not appropriate for everyone, the agency said. Of 328 people clinically evaluated six months after having the surgery, 88 percent had 20/20 vision, the FDA said. The most common complications from the procedure included surgical debris, dry eye, glare and the appearance of a halo. The device is produced by Carl Zeiss Meditec Inc., based in Dublin, Calif.

Does Your Child Need Eyeglasses?

Posted 19 Aug 2016 by Drugs.com

FRIDAY, Aug. 19, 2016 – Nearly 80 percent of what kids learn in their first 12 years is through their vision. Your back-to-school checklist should include making sure your child's eyesight is OK, an eye expert says. "Glasses may be the most important back-to-school supply many children get this year," Eileen Gable, a Loyola University eye specialist, said in a university news release. Vision problems are the fourth most common disability in children. But they often go undetected, she noted. "Vision is complex and tricky for family members to assess. Children with normal sight in just one eye can appear to see really well when, in fact, they do not. Not having good vision in both eyes can cause poor depth perception and, if left untreated, can last a lifetime and limit career choices," Gable said. Look to your child's behavior for clues that he or she isn't seeing clearly. "If your ... Read more

Vision Trouble Can Dim Life's Prospects

Posted 28 Jul 2016 by Drugs.com

THURSDAY, July 28, 2016 – People with vision problems may face a higher risk of unemployment, poverty and mental health problems, a new British study suggests. "Our focus has mostly been on severe visual loss and treating the eye diseases that cause it," said Mary Frances Cotch, chief of epidemiology at the U.S. National Eye Institute. "This study is saying we probably shouldn't wait until that time since people with mild visual loss are being affected by their condition." The British researchers based their findings on a previous project that examined the health of more than 112,000 volunteers in the United Kingdom. The average age of the volunteers was 57, and 55 percent were female. Less than 1 percent of the participants were blind or had severely limited vision. But 23 percent had limited vision in one or both eyes, often despite having contacts or eyeglasses, according to the ... Read more

Routine Eye Exams See Vision Problems You Miss

Posted 14 Jul 2016 by Drugs.com

WEDNESDAY, July 13, 2016 – Routine eye checkups often pick up unnoticed problems, particularly in older adults, a new study says. "In asymptomatic patients, comprehensive routine optometric eye examinations detect a significant number of new eye conditions and/or results in management changes," said the study's author, Elizabeth Irving, and her colleagues from the University of Waterloo in Ontario, Canada. More than half of people with no new symptoms or vision problems receive new prescriptions or treatment changes as a result of routine eye exams, the researchers found. The need for vision prescription changes was found for two out of five people, the study noted. Meanwhile, 16 percent were diagnosed with a new eye condition and 31 percent had a change in their ongoing care, researchers found. The study included data on nearly 6,400 patients who visited a university eye clinic over ... Read more

FDA Approves Eye Implant for Aging Boomers

Posted 1 Jul 2016 by Drugs.com

THURSDAY, June 30, 2016 – An implant that helps the aging eye focus on small print and nearby objects has been approved by the U.S. Food and Drug Administration. The implant is placed in the cornea (the clear, front surface) of one eye in people with presbyopia, an age-related loss of the ability to change the focusing power of the eye. "Given the prevalence of presbyopia and the aging of the baby boomer population, the need for near vision correction will likely rise in the coming years," Dr. William Maisel said in an agency news release. Maisel is deputy director for science and chief scientist in the FDA's Center for Devices and Radiological Health. The implant resembles a tiny contact lens smaller than the eye of a needle. It is approved for use in people aged 41 to 65 who have not had cataract surgery, can't focus clearly on near objects or small print, and require reading glasses ... Read more
