Topiramate induced acute transient myopia: a case report

Introduction: Topiramate is a sulfamate-substituted monosaccharide mainly used to treat epilepsy in children and adults and for prophylaxis of migraine. This article describes a case of topiramate induced acute transient myopia. The underlying mechanism and management is discussed.
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

Among dietary factors, learning and behavior are influenced not only by nutrients, but also by exposure to toxic food contaminants such as mercury that can disrupt metabolic processes and alter neuronal plasticity. Neurons lacking in plasticity are a factor in neurodevelopmental disorders such as autism and mental retardation. Essential nutrients help maintain normal neuronal plasticity. Nutritional deficiencies, including deficiencies in the long chain polyunsaturated fatty acids
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.

Neural plasticity in adults with amblyopia

...Amblyopia is a neuronal abnormality of vision
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....

Amblyopia: is visual loss permanent?

...Older people with a history of amblyopia who develop visual loss in the previously normal eye can experience recovery of visual function in the amblyopic eye over a period of time. This recovery in visual function occurs in the wake of visual loss in the fellow eye and the improvement appears to be sustained.
...


Comments: The more I look at neuroplasticity the more I'm surprised that my OMD and some OD colleges still insists that you cannot treat amblyopia after a certain age...you can treat amblyopia at any age! Click on the title above for full text of the article. DM

Plasticity and restoration of vision after visual system damage

Sabel BA. Plasticity and restoration of vision after visual system damage: an update. Restor Neurol Neurosci. 2008;26(4-5):243-7.

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.

Mouse Study Points to Possible Down Syndrome Treatment

..Drugs that stimulate norepinephrine signaling might allow for normal cognitive development in children with Down syndrome, said researchers who tested the hypothesis in mice.

In animals with three copies of chromosome 16 -- a model of the chromosome 21 trisomy responsible for human Down syndrome -- an oral prodrug for norepinephrine called droxidopa almost normalized the mice's performance on standardized cognitive function tests, reported Ahmad Salehi, MD, PhD, of the VA Palo Alto Health Care System in Palo Alto, Calif., and colleagues online in Science Translational Medicine...

Prevalence of Myopia and Hyperopia in 6- to 72-Month-Old African American and Hispanic Children

...Prevalence of myopia was higher in African American (6.6%) compared with Hispanic children (3.7%; P<0.001). Hispanics showed a higher prevalence of hyperopia than African American children (26.9% vs. 20.8% respectively, P<0.001). The prevalence of myopia showed a significant decreasing trend with age (P<0.001). Hyperopia prevalence reached a low point at approximately 24 months of age but increased and remained higher than that thereafter. No significant gender differences were found in the prevalence of refractive error for either ethnic group....

Ophthalmic surgery complications to H1N1 vaccine reported

The H1N1 vaccine may have immune-related ophthalmic consequences in specific cases, according to anecdotal reports.

"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.

Advanced Cell Technology seeks to test embryonic stem cells to treat blindness.

From AOA First Look:

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.

Sounds During Sleep Boost Memory

...Researchers are learning more and more about how our senses aid memory and learning while we sleep.

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.

Iron deficiency anemia in infancy and reach and grasp development

This study assessed 9 kinematic characteristics of infants’ reach and grasp to test the hypothesis that iron deficiency anemia (IDA) delays upper extremity motor development. Reach and grasp movements, recorded with a 3D-motion capture system, were compared in 9- to 10-month-old infants (4 IDA vs. 5 iron-sufficient [IS]). Based on normative motor development data available for 6 characteristics, the results indicated poorer upper extremity control in IDA infants: 2 characteristics showed statistically significant group differences despite small n, and the other 4 had strong indications for such results (effect sizes [Cohen's d] > 1.2). The remaining 3 measures, for which normative studies do not show developmental changes in this age period, showed significant or moderate-to-large effect differences. Poorer upper-extremity control in IDA infants in the short-term in this study and in the long-term despite iron therapy in other studies suggests that a motor intervention may be warranted when IDA is detected in infancy.

Babies With Moderately Low Birthweight Are At Risk Of Neurological Immaturity

Making Memories Means New Neurons Must Erase Older Ones

Short-term memory may depend in a surprising way on the ability of newly formed neurons to erase older connections. That's the conclusion of a report in the November 13th issue of the journal Cell, a Cell Press publication, that provides some of the first evidence in mice and rats that new neurons sprouted in the hippocampus cause the decay of short-term fear memories in that brain region, without an overall memory loss.

Interview with Susan Barry, Ph.D., Author of “Fixing My Gaze”

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.
