Brain 'Rewires' to Work Around Early-Life Blindness

Posted 8 days ago by Drugs.com

WEDNESDAY, March 22, 2017 – Blindness at an early age triggers the brain to make new connections that enhance hearing, smell and touch, as well as memory and language, a new study suggests. Researchers used MRIs to scan the brains of 12 people who were born blind or lost their sight by age 3. The scans showed a number of changes in the brains of the people who were blind that weren't present in scans from people who could still see. Changes caused by early blindness "may be more widespread than initially thought," lead author Corinna Bauer, a scientist at Massachusetts Eye and Ear, said in a hospital news release. "We observed significant changes not only in the occipital cortex [where vision is processed], but also areas implicated in memory, language processing and sensory motor functions," added Bauer. Learning more about these connections could lead to more effective rehabilitation ... Read more

For Seniors, Treatment for One Eye Disease May Cause Another

Posted 14 days ago by Drugs.com

THURSDAY, March 16, 2017 – Drugs that preserve vision in people with the eye disease called age-related macular degeneration might increase the risk of another eye condition – glaucoma, a new study suggests. People who received at least seven eye injections of the drug bevacizumab (Avastin) each year to treat macular degeneration have a higher risk of eventually needing surgery to treat glaucoma, the Canadian study found. But, the researchers aren't suggesting that people forgo these treatments for macular degeneration. These drugs help stave off a previously untreatable cause of blindness in the elderly, and should continue to be used, the researchers said. And, if glaucoma does develop, treatments are available. "Even though there may be a risk here, this doesn't mean you should not be getting injections for macular degeneration," said study lead author Dr. Brennan Eadie. He's an ... Read more

Stem Cells Hold Promise, Peril in Treating Seniors' Eye Disease

Posted 15 days ago by Drugs.com

WEDNESDAY, March 15, 2017 – Stem cells may offer new hope for people losing their vision to age-related macular degeneration, but that promise can come with some peril, new research shows. In one report, three older women were permanently blinded at a Florida eye clinic that performed unproven stem cell treatments on their eyes in 2015, said senior study author Dr. Jeffrey Goldberg. He's chair of ophthalmology for the Byers Eye Institute at Stanford University in Palo Alto, Calif. The women all thought the stem cell therapy was part of a clinical trial, but there's no evidence that a genuine clinical trial was taking place, Goldberg noted. "It appears the patients were lured in with the promise of a research protocol and it's not clear that they were actually signed up for any research," Goldberg said. "They were just injected with these cells of some sort." The women, aged 72 to 88, ... Read more

Health Tip: Don't Contaminate Contact Lenses

Posted 15 days ago by Drugs.com

-- Germs on poorly handled contact lenses can lead to serious eye infections. To avoid this problem, the American Optometric Association suggests: Don't wash your hands with a creamy soap, which can leave a film on lenses. Never create a homemade saline solution, which can damage lenses. Don't put lenses in your mouth to moisten them. Don't store or wash lenses in tap water. Don't let anyone else wear your lenses. Don't wear contact lenses to sleep if you've been in a hot tub, pool, lake or ocean. Read more

Zika Virus May Also Harm the Heart

Posted 9 Mar 2017 by Drugs.com

THURSDAY, March 9, 2017 – Zika may cause heart problems in some people infected with the mosquito-borne virus, researchers report. A new study has identified nine Venezuelan patients who suffered from heart problems shortly after coming down with Zika virus symptoms. Eight of the nine patients developed dangerous heart rhythm disorders, and two-thirds had evidence of heart failure, a condition in which the heart isn't pumping enough blood to meet the body's needs. Lead researcher Dr. Karina Gonzalez Carta said doctors should consider electrocardiograms (ECG) for all Zika-infected patients, and follow-up testing if an irregular heartbeat is detected. "While we anticipated we would see cardiovascular effects from Zika, we were surprised at the severity of the findings," said Carta, a Venezuelan native, and a cardiologist and research fellow at the Mayo Clinic, in Rochester, Minn. This is ... Read more

Eye Exam Might Help Spot Poor Circulation in Legs

Posted 9 Mar 2017 by Drugs.com

WEDNESDAY, March 8, 2017 – Could a routine eye exam some day point to trouble with circulation in the legs? New research suggests it might be possible. Researchers at Johns Hopkins University in Baltimore said changes in the eye's retina may help spot people at risk for a narrowing of the large blood vessels in the legs – a condition called peripheral artery disease (PAD). "PAD is estimated to affect approximately 8.5 million Americans above the age of 40 years and is associated with significant morbidity, mortality and quality of life impairment," noted one heart specialist, Dr. Samy Selim. He's an interventional cardiologist at Northwell Health's Southside Hospital in Bay Shore, N.Y. And while the disability from PAD is serious and widespread, "physician screening for PAD is not satisfactory, to say the least," Selim said. The new study was led by Hopkins researcher Chao Yang and is ... Read more

Kids Should Be Screened for Lazy Eye by Age 5

Posted 28 Feb 2017 by Drugs.com

TUESDAY, Feb. 28, 2017 – Young children should be screened at least once for lazy eye before they turn 5 years old, a U.S. panel of experts says. The U.S. Preventive Services Task (USPSTF) is still advising parents to have their kids screened at least once for lazy eye or its risk factors. Screening should be done when the children are between the ages of 3 and 5 years old. These draft guidelines are an update to 2011 recommendations. Early identification of lazy eye – technically called amblyopia – is critical. If the condition isn't treated by the time a child is between the ages of 6 and 10 years, vision can be permanently affected, the experts said. With lazy eye, the brain and one eye don't communicate properly. Symptoms may include a wandering eye, eyes that don't seem to work together, or poor depth perception, the experts explained. It's estimated that up to 6 percent of ... 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

FDA Approves Genentech’s Lucentis (ranibizumab) for Myopic Choroidal Neovascularization

Posted 10 Feb 2017 by Drugs.com

South San Francisco, CA – January 5, 2017 – Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), announced today that the U.S. Food and Drug Administration (FDA) has approved Lucentis® (ranibizumab injection) 0.5 mg for the treatment of patients with myopic choroidal neovascularization (mCNV), a complication of severe near-sightedness that can lead to blindness. Lucentis is the first FDA-approved anti-vascular endothelial growth factor (VEGF) therapy to treat mCNV in the U.S. This is the fifth FDA-approved indication for Lucentis since the medicine was launched in 2006. This approval is based on the results of the Phase III RADIANCE study, which demonstrated that treatment with Lucentis provided superior visual acuity gains in people with mCNV compared to verteporfin photodynamic therapy (vPDT). At three months, average visual acuity gains for patients treated with ... Read more

Laundry Detergent Pods Linked to Eye Burn Danger in Kids

Posted 2 Feb 2017 by Drugs.com

THURSDAY, Feb. 2, 2017 – Liquid laundry detergent pods may be convenient, but young children are suffering vision-threatening burns from the chemicals inside them in increasing numbers, a new study finds. Between 2012 and 2015, more than 1,200 preschoolers in the United States suffered eye burns from these single-use detergent pods. In 2012, only 12 such burns were reported. By 2015, that number was almost 500. "These pods look like toys, they look like candy, and kids are finding them, playing with them, puncturing them, and the chemicals inside the pods are getting into their eyes," said lead researcher Dr. R. Sterling Haring, from the Johns Hopkins University Bloomberg School of Public Health in Baltimore. Injuries most often occur when children play with the detergent pods and they break and the liquid squirts into their eyes. Burns also happen when kids get the soap on their hands ... Read more

Experimental Drug Shows Promise for Sight-Stealing Eye Condition

Posted 18 Jan 2017 by Drugs.com

WEDNESDAY, Jan. 18, 2017 – An experimental drug may one day make treatment simpler for patients suffering from vision-threatening age-related macular degeneration, researchers say. So far, the drug – called AXT107 – has been only tested on mice and rabbits, but it requires far fewer injections than current therapy to prevent vision loss. Current treatment requires frequent injections directly into the eye. "We anticipate injection of AXT107 in humans may have a substantially longer effect than current treatment," said lead researcher Dr. Peter Campochiaro. He's a professor of ophthalmology at Johns Hopkins University in Baltimore. "Instead of eye injections every four to six weeks, we hope it would be several months between injections," he said. The drug test in rabbits lasted only two months, but the drug appeared both safe and effective, Campochiaro said. Researchers hope to start ... Read more

Parents Have Mixed Views on When to Keep Sick Kids Out of School

Posted 16 Jan 2017 by Drugs.com

MONDAY, Jan. 16, 2017 – American parents don't always agree when to keep their children home sick from school, a new poll reveals. The poll included almost 1,500 parents nationwide. All had at least one child aged 6 to 18. The research found that 75 percent had kept their child home sick from school at least once in the past year. The main reasons for keeping a child home were concerns their illness would get worse or spread to classmates. But the University of Michigan C.S. Mott Children's Hospital National Poll on Children's Health found that parents have differing views about how sick is too sick. Or the importance of sick day consequences, such as parents missing work or kids missing tests. Parents of children aged 6 to 9 were more likely to say that health-related concerns were a very important factor in keeping children home from school. Among parents of high schoolers, 40 ...

'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

Lengthy Space Missions May Harm Astronauts' Vision

Posted 28 Nov 2016 by Drugs.com

MONDAY, Nov. 28, 2016 – Researchers have pinpointed the cause of a vision problem affecting astronauts who have completed long-duration space missions. The condition – called visual impairment intracranial pressure (VIIP) – has been reported by nearly two-thirds of astronauts after extended time on the International Space Station. The astronauts experienced blurred vision and were found to have structural changes, such as flattening at the back of their eyeballs and inflammation in their optic nerves. VIIP is caused by changes in the volume of clear fluid found around the brain and spinal cord, according to the study. "People initially didn't know what to make of it, and by 2010 there was growing concern as it became apparent that some of the astronauts had severe structural changes that were not fully reversible upon return to Earth," study lead author Noam Alperin said in a news ...
