Scientists Scour Genome Searching for Cause of AMD
Within a decade, opticians will see an increasing number of patients dealing with the effects of macular degeneration (AMD). What's happing in the field?
"Teams of geneticists from nine countries, involving more than 100 scientists, analyzed the genes of more than 33,000 individuals in the hope of finding genetic variations responsible for age-related macular degeneration (AMD)," according to a Medical News Today post. "Their research, involving complex computational analysis of more than 12 million genetic variations across the human genome, identified 52 variations associated with the disease. By identifying these genetic variations, spread across 34 gene regions, scientists are a step closer to developing diagnostics that identify which patients are at high risk for acquiring the disease and formulating therapeutics either to prevent or treat the disease caused by these genetic variations."

New Window for Treating Cataracts? Study Indicates Yeap!
When's the best time to treat cataracts? A new study, reported by Science Daily, may have identified the window between non-treatment and removal. "In a new study, scientists found that throughout our lifetime, levels
of a key protein decline, and may be an early warning sign of a
developing cataract. The study suggests that there is a window before
cataracts develop when there may be time to intervene and prevent them." Read more.
NEI Notes January as Glaucoma Awareness Month
Glaucoma Awareness Month starts next week. The disease is a major cause of vision loss in the U.S. It affects about 3 million Americans, and that number could more than double by 2050. “Early detection by having a comprehensive dilated eye exam is key to protecting vision,” said Paul A. Sieving, M.D., Ph.D., director of the NEI (National Eye Institute). Anyone can get glaucoma, but African Americans over age 40, everyone over age 60, especially Mexican Americans, and people with a family history of glaucoma are at higher risk. People at higher risk should have a comprehensive dilated eye exam every one to two years. Glaucoma is a group of diseases that damages the optic nerve, the bundle of nerve cells that relays visual information from the eye to the brain. In the most common form of glaucoma, called primary open angle glaucoma, nerve damage results from increased pressure inside the eye. Increased eye pressure occurs when the fluid that circulates in the eye drains too slowly. Read more.
What You See Ain't What You Get!!!
What you see ain't always what you get--as far as your visual cortex is concerned. How, then, does this massive region of the brain right the world we see?
"What we see is not only based on the signals that our eyes send to our brain, but is influenced strongly by the context the visual stimulus is presented in, on our previous knowledge, and expectations," goes the writeup on Medical News Today. "Optical illusions, as the one shown here, illustrate how important such non-visual, contextual information is for our perception. The visual cortex receives this additional information from other brain areas and uses it to allow us to understand and interpret the visual world. Prof. [Sonja] Hofer and her team [at the biozentrum at the University of Basil, Switzerland] measured the specific signals transmitted to visual cortex from the Thalamus, and found that the Pulvinar not only conveyed visual signals but is also one of the brain areas that provide additional information about the context of visual stimuli." Nature Neuroscience published their results. Read more.

Vision Plan Loses Lawsuit
"A health insurance company angry about losing a bid for the state’s vision contract just lost their case in Shawnee County District Court," notes KSNT. "Superior Vision Services, Inc. based in Rancho, Cordova, CA had been the sole provider of vision insurance for the State Employee Health Plan or SEHP. However, following a new request for proposal, the Kansas State Employees Health Care Commission (HCC) awarded the contract to Surency Life and Health Insurance on April 20, 2015. Surency is a Kansas-based company with offices in Wichita and Leawood. Superior sued the state of Kansas on several grounds in October, naming several agencies and entities in the lawsuit. Today, the court ruled that there was substantial evidence supporting the decision to accept Surency’s proposal. The court wrote that the decision was 'no so wide of the mark as to be deemed unreasonable, arbitrary, or capricious.'" Read more.

Can Seeing Make You "Deaf"?
"Concentrating attention on a visual task can render you momentarily 'deaf' to sounds at normal levels, reports a new UCL study funded by the Wellcome Trust," notes Medical News Today. "The study, published in the Journal of Neuroscience, suggests that the senses of hearing and vision share a limited neural resource. Brain scans from 13 volunteers found that when they were engaged in a demanding visual task, the brain response to sound was significantly reduced. Examination of people's ability to detect sounds during the visual demanding task also showed a higher rate of failures to detect sounds, even though the sounds were clearly audible and people did detect them when the visual task was easy."

Should Seeing Be Believing?
"Our vision and hearing aren't as reliable as we might think, according to a study by life scientists at UCLA," writes Medical News Today. "'Our basic sensory representation of the world -- how information from our eyes and ears is processed by neurons in the brain -- is inaccurate,' said Ladan Shams, an associate professor of psychology in the UCLA College and senior author of the research, which was published in the journal PLOS Computational Biology. 'We tend to view our senses as flawless and think that to see is to believe,' she said. 'So it's eye-opening to learn that our perceptions are flawed.' Shams and her colleagues conducted the research in part because there had never been a comprehensive study to examine whether humans' 'spatial localization' ability -- that is, whether we can immediately and accurately perceive where an object is located -- is as well-honed as we believe it to be."

Coloradan Receives Bionic Eye to Treat Retinitis Pigmentosa
"The Denver Post reported on December 10 that a Colorado woman received Colorado's first bionic eye transplant at the Eye and Vision Care Center of the University of Colorado. The patient, Ms. Jamie Carley suffers from retinitis pigmentosa (RP). The degenerative disease rendered her virtually blind," reports the Examiner.
"The November surgery took over five hours. Surgeons implanted a microchip into the retina of one of Ms. Carley's eyes. When she wears specially designed glasses with an attached camera, the video images transmit to the microchip. In turn, the optic nerve is stimulated, with visual information then sent to her brain. Although she can not see normally, her vision is now good enough to see outlines and shadows. As she progresses through a long period of rehabilitation, surgeons hope she will improve her vision by using her brain to interpret the new optical signals. The surgery offers great hope for the future. Currently, it is prohibitively expensive. The implanted device alone cost $150,000. Moreover, the implant only works for patients afflicted with RP."

J.D. Powers Ranks Vision Plans
Contact Lens Market to Reach $13.5 Billion in 5 Years
The contact lenses market will grow to approximately $13.5 billion in the next five years,. according to a Hexa Research study. A portion of the growth will come with the increasing prevalence of such eye diseases as astigmatism, hypermetropia and myopia. An increasing population, fashion, and tech advances will also fuel the growth. As per the 2009 report, by contact lens spectrum, study says that almost 150 million people are using contact lenses. Additionally, plano sunglasses have pushed the contact lenses market and led to the reduction in need for dependency on spectacles. As PRK and LASIK surgeries acceptance are increasing globally, they hinder growth of the CL market.

Owner of Eyewear Store Accussed of Taking $3.4 Million in Fraudulent Loans
"The owner of two Brooklyn eyeglass stores applied for and received more than $3.4 million in fraudulent loans, then spent much of the money shopping for his girlfriend at Saks Fifth Avenue and Bergdorf Goodman, paying rent on a Manhattan condominium and financing trips to Atlantic City casinos, prosecutors said on Wednesday," reports the New York Times. "The charges against the merchant, Maksim Grinberg, who operates D&M Optical and 9th Street Vision out of the same building at Ninth Street and Fifth Avenue in Park Slope, were laid out in a 148-count indictment filed by the Brooklyn district attorney’s office and unsealed in State Supreme Court. Standing handcuffed, Mr. Grinberg, 43, pleaded not guilty at an arraignment on Wednesday. From 2010 to this year, Mr. Grinberg submitted applications to seven financial institutions, including arms of major banks like Wells Fargo, seeking loans he said would go toward buying medical equipment, according to the indictment."

Novartis Considers Selling Alcon
"Novartis ($NVS) is mulling a sale of its contact lens care business as the company faces sluggish growth for its Alcon unit and targets eye care innovation to swing its numbers northward," states a post from Fierce Medical Devices. "The proposed sale is still in early stages and Novartis might decide not to go through with a sale, people familiar with the matter told Bloomberg. But if the Swiss company does unload the business, which includes products to clean lenses, it could bring in $1.6 billion, Kepler Cheuvreux analyst Fabian Wenner told the news outlet. Some analysts set that number lower, though, with Safra Sarasin analysts saying the sale would fetch no more than $1 billion. A sale would come at a critical moment for Novartis, as it deals with slumping numbers for its contact care business and Alcon unit." Read more.

Rise in Myopia Means a Boon for Eyewear Industry
"According to mounting research, myopia (nearsightedness) among the young has become a global epidemic. In the United States, myopia rates have roughly doubled over the last generation. A recent study published in JAMA reports that in China (where rates of myopia have skyrocketed to roughly 90% among urban youth), the major cause could be a lack of sun exposure. But young adults aren’t the only ones struggling to see clearly. Older adults are also looking for treatments that address their age-related vision problems. Amid rising demand, the eye care industry is poised to accelerate. It’s already developing new technologies that not only treat, but also prevent (and in some cases eliminate) vision problems," goes the post on Forbes. "With increasing demand from every age group, the $36 billion eye care industry has a bright future. The industry, which includes eye care professionals (opticians, optometrists, and ophthalmologists) and products (eye glasses, contact lenses, and corrective surgeries,) posted a steady combined annual growth rate of 3.4% from 2006 to 2012, outpacing the average growth of the economy at large (2.9%) over those years. Forecasters expect this rate to increase to 5.0% from 2014 to 2019." Read more, especially about the growth of myopia.
Researchers Turn Stem Cells into Retinal Ganglion Cells
"Johns Hopkins researchers have developed a method to efficiently turn human stem cells into retinal ganglion cells, the type of nerve cells located within the retina that transmit visual signals from the eye to the brain. Death and dysfunction of these cells cause vision loss in conditions like glaucoma and multiple sclerosis," according to Science Digest. "The laboratory process, described in the journal Scientific Reports, entails genetically modifying a line of human embryonic stem cells to become fluorescent upon their differentiation to retinal ganglion cells, and then using that cell line for development of new differentiation methods and characterization of the resulting cells."
