During this time, WLS-AM radio listeners will hear award-winning host Pat Cassidy emcee the event live from the Hotel InterContinental Starbucks store located at 505 North Michigan Avenue. The broadcast will feature interviews with local TV, sports and political celebrities, including Actor Joe Mantegna, Chicago White Sox Manager Ozzie Guillen and others. In addition, WLS-AM will air features about autism, interviews with ESMC families and offer facts about autism throughout the day.
Please tune into 890AM radio throughout the day to hear interviews, news and ways to help this cause.
Case presentation: A 34-year-old female complained of sudden onset of blurred vision, 9 days prior to this she had commenced topiramate therapy for migraine prophylaxis. Visual acuity was reduced to 6/36 right eye and 2/60 left eye. Examination revealed ocular anatomical and myopic refractive changes which resolved quickly following discontinuation of the drug.
Conclusion: Ophthalmologists need to be aware of the potential ocular side effects of topiramate. Although relatively rare prompt recognition is key so appropriate management can be instituted.
Comments: I work with many patients who take Topomax (Topiramate) for many different reasons....besides myopia, watch out for narrow angle glaucoma. Click on the title to get the full article. DM
Mercury exposure, nutritional deficiencies and metabolic disruptions may affect learning in children
eicosapentaenoic acid and docosahexaenoic acid, the amino acid methionine, and the trace minerals zinc and selenium, have been shown to influence neuronal function and produce defects in neuronal plasticity, as well as impact behavior in children with attention deficit hyperactivity disorder. Nutritional deficiencies and mercury exposure have been shown to alter neuronal function and increase oxidative stress among children with autism. These dietary factors may be directly related
to the development of behavior disorders and learning disabilities. Mercury, either individually or in concert with other factors, may be harmful if ingested in above average amounts or by sensitive individuals. High fructose corn syrup has been shown to contain trace amounts of mercury as a result of some manufacturing processes, and its consumption can also lead to zinc loss. Consumption of certain artificial food color additives has also been shown to lead to zinc deficiency. Dietary zinc is essential for maintaining the metabolic processes required for mercury
elimination. Since high fructose corn syrup and artificial food color additives are common ingredients in many foodstuffs, their consumption should be considered in those individuals with nutritional deficits such as zinc deficiency or who are allergic or sensitive to the effects of mercury or unable to effectively metabolize and eliminate it from the body.

that is often considered irreversible in adults. We found
strong and significant improvement of Vernier acuity in
human adults with naturally occurring amblyopia following
practice. Learning was strongest at the trained orientation
and did not transfer to an untrained task (detection), but it
did transfer partially to the untrained eye (primarily at the
trained orientation). We conclude that this perceptual learning
reflects alterations in early neural processes that are
localized beyond the site of convergence of the two eyes. Our
results suggest a significant degree of plasticity in the visual
system of adults with amblyopia....

The traditional view that visual system damage is permanent has given way to a more optimistic view. Visual loss does not remain unchanged but it can recover spontaneously to some extent. Even when the period of spontaneous recovery has ended there is still additional potential for plasticity and regeneration, even months or years after the lesion. There are two fundamental approaches to harvest this plasticity potential: (i) to rescue dying cells or induce axonal regeneration of visual system neurons through biological (pharmacological) means and (ii) to capture the residual vision capacities and improve their functions by behavioural training. Visual training can be used to activate residual visual neurons either in the blind sectors of the visual field through alternative pathways or it can be used to activate partially damaged regions in the border zone near the lesion site. Another example of post-lesion neuroplasticity is the ability of the intact visual field sectors to (spontaneously) take over functions and this is seen, for example, in macular degeneration and even in developmental disorders, such as amblyopia who benefit from training even many years beyond the critical period. Just as plasticity after brain damage is well recognized in other functional systems (motor, somatosensory), plasticity of the visual system is now gradually being recognized as a useful mechanism whereby the brain compensates for its functional loss, either spontaneously or by repetitive visual stimulation.

"Recently, graft rejection occurred in two of my patients who received the vaccination 2 weeks before. I had the opportunity to discuss this issue in public at the AAO meeting, and other surgeons said they had similar cases," Jorge L. Alió, MD, PhD, of Vissum Corporation in Alicante, Spain, said in an interview with Ocular Surgery News.
AFP (11/19, Oberman) reported that "embryonic stem cell therapy got a step closer to the clinic Thursday after" researchers from Advanced Cell Technology "said they filed a request for" Food and Drug Administration "approval of human trials" involving "a single injection of retinal cells derived from embryonic stem cells" to treat Stargardt's disease, a common type of "juvenile blindness." The technique "works by replacing lost" retinal pigment epithelium cells "which maintain the photoreceptors needed for vision," explained Robert Lanza, MD, the company's chief scientific officer.
Reuters (11/20, Fox) reports that if the agency approves the application, a human phase I/II trial would take place in 12 patients to prove safety and efficacy.
The UK's Independent (11/20) reports that Advanced Cell Technology plans "to follow this with an application to treat age-related macular degeneration, which...is the most common cause of blindness." In animal tests, "transplants of the human cells into rats with macular degeneration resulted in a '100 percent improvement' in vision with no side-effects, Dr. Lanza said."
The Los Angeles Times (11/19, Kaplan) "Booster Shots" blog reported that Stargardt's disease "is a childhood version of macular degeneration and affects about one in 10,000 kids. Patients typically begin to lose their central vision between the ages of six and 20," with "about half of victims" becoming "legally blind by age 50." In most cases of the disease, which has no cure, "children inherent a faulty version of the ABCA4 gene or the CNGB3 gene from both parents," which causes "photoreceptor cells in the retina" not to "get enough fuel," so "they atrophy." The UK's Telegraph (11/20, Moore) also covers the story.
Several years ago, scientists reported that scents smelled during sleep could help trigger learning by boosting the brain's ability to retain new memories.
Now a new study suggests sound can do the same thing.
Study participants were better able to recall a newly learned memory when they were exposed to sound cues for the memory while they napped, even though they did not remember hearing the sounds upon awaking....

There is no evidence that radiation from televisions has resulted in human injury, according to the Federal Drug Administration. When used under normal conditions, TVs do not pose a radiation hazard, it says. In 1969, the FDA set a standard to limit X-ray emissions from TV receivers, which still applies. To avoid eyestrain, studies recommend sitting 18 to more than 30 inches from monitors and TV sets, depending on the viewer’s existing visual issues, and other factors such as lighting, says Kent M. Daum, a professor in the Illinois College of Optometry and member of the American Optometric Association.

As many readers already know, there is an exciting book that has recently been published by woman who achieved great success with vision therapy at age 48. It is called “Fixing My Gaze” by Susan Barry, Ph.D. The book has been very popular and at one point was the 367th most sold book on Amazon.com.
When the book was released, I pre-ordered copies for my office. I read it and had the staff read it. I loved the way Dr. Barry writes and her accessibility. In fact, I liked it so much that I recently held an online contest to give a copy away.
Well, the contest caught the attention of “Stereo Sue”, as she is nicknamed, and she graciously agreed to an online interview.
