Optometrists: Nintendo 3DS could ID vision issues

....U.S. eye specialists are welcoming the Nintendo 3DS game device, dismissing the manufacturer's warnings that its 3-D screen shouldn't be used by children 6 or younger because it may harm their immature vision.


On the contrary, the optometrists say, it's a good idea to get your kids to try the 3-D screen, especially if they're younger than 6. It won't do any harm, they say, and it could help catch vision disorders that have to be caught early to be fixed.
"The 3DS could be a godsend for identifying kids under 6 who need vision therapy," said Michael Duenas, associate director for health sciences and policy for the American Optometric Association.....

Comments: As you read this article (click on title to read full article), you might notice a bit of a bias towards the MD point of view. This point of view tends to limit what anyone with problems seeing 3D can do. If you child has problems seeing 3D (don't forget to ask them)...take them to an optometrist who can help. You can find such a doctor at http://www.aoa.org/ and http://www.covd.org/. DM

Improved Cognitive Function After Transcranial,Light-Emitting Diode Treatments in Chronic,Traumatic Brain Injury: Two Case Reports

An article in Photomedicine and Laser Surgery noted that: ...Significant benefits have been reported following application of transcranial, low-level....laser therapy (LLLT) to humans with acute stroke and mice with acute TBI....Transcranial LED may improve cognition, reduce costs in TBI treatment, and [can] be applied at home.....

Comments: It's interesting that medicine is starting to accept "light therapy" for any number of conditions and yet tends to be skeptical of using light to improve vision function. The College of Syntonic Optometry states: Syntonics or optometric phototherapy, is the branch of ocular science dealing with the application of selected light frequencies through the eyes. It has been used clinically for over 70 years in the field of optometry with continued success in the treatment of visual dysfunctions, including strabismus (eye turns), amblyopia (lazy eye), focusing and convergence problems, learning disorders, and the aftereffects of stress and trauma. In recent years, Syntonics has been shown to be effective in the treatment of brain injuries and emotional disorders.... I have not recently investigated the use of light for treatment in the areas noted above, but a nice review of the topic can be found by reading

Some Blind People 'See' With Their Ears

...Dr. Olivier Collignon of the University of Montreal's Saint-Justine Hospital Research Centre compared the brain activity of people who can see and people who were born blind, and discovered that the part of the brain that normally works with our eyes to process vision and space perception can actually rewire itself to process sound information instead....

The Brain Networks Involved In How We Recognise People

...Human social interactions are shaped by our ability to recognise people. Faces and voices are known to be some of the key features that enable us to identify individual people, and they are rich in information such as gender, age, and body size, that lead to a unique identity for a person. A large body of neuropsychological and neuroimaging research has already determined the various brain regions responsible for face recognition and voice recognition separately, but exactly how our brain goes about combining the two different types of information (visual and auditory) is still unknown. Now a new study.....

Stem Cells May Provide Treatment For Brain Injuries

Prozac Reorganizes Brain Plasticity

....chronic treatment of adult mice with fluoxetine (Prozac) caused changes to granule cells, one of the main types of neuronal cells inside the hippocampus, and to their connections with other neuronal cells. The granule cells appeared to undergo serotonin-dependent 'dematuration', which increased their activity and reversed adult-type plasticity into an immature state. These changes to the cell's plasticity were associated with increased anxiety and in alternating between periods of hyper or hypo activity. ....

Creativity Is An Upside To ADHD

Conscious And Unconscious Perception And How Flexibly The Brain Processes Images

...Our brains process many more stimuli than we become aware of. Often images enter our brain without being noticed: visual information is being processed, but does not reach consciousness, .... what is the difference between conscious and unconscious perception, and can both forms of perception be changed through practice? These questions are important not only for basic research, but also for the treatment of patients with perceptual deficits due to brain lesions e.g. following a stroke. Scientists at the MPI for Brain Research in Frankfurt/Main could now show that seeing can be trained. Their tests revealed that the brain regions underlying the learning effects on conscious perception are different than the ones underlying the learning effects on the mere processing of stimuli. ...

THE AMERICAN OPTOMETRIC ASSOCIATION AND 3D@HOME CONSORTIUM SIGN MEMORANDUM OF UNDERSTANDING



Organizations Will Share Scientific, Clinical Research for Better Understanding of 3D/S3D Viewing and Promotion of Vision Health

New York, NY, March 16, 2011 /PRNewswire/ — The American Optometric Association (AOA) and its 36,000 members today announced its partnership with the 3D@Home Consortium, a group of more than 45 companies, to improve the understanding of 3D/S3D viewing as a safe and appropriate technology for all viewing audiences. The parties signed a Memorandum of Understanding (MOU) today, stating their intent to share data and jointly promote vision health utilizing stereoscopic 3D displays.


The cooperative relationship will be a conduit for the exchange of the most current information and research. Both the AOA and the 3D@Home Consortium acknowledge vision and eye health may enhance consumers’ abilities to view 3D/S3D images, and ultimately increase their use of such technology. The two groups will collaborate in the development of common interest strategies, exchange of ideas, and shared best practices.


Potential projects covered by the MOU include: 1) enhanced public and professional communication; 2) development and design of 3D/S3D based vision risk assessment tools; 3) development and design of applied therapies; 4) providing new integrated efforts for quality improvement and evaluation; and 5) improved public health and vision and eye health.


Both groups will be encouraging their constituents to incorporate the use of stereoscopic testing and educational materials in their products, helping the public build an appreciation for the importance of optometry-delivered vision and eye health care, as well as the importance of yearly comprehensive eye exams. For more information, visit http://www.3deyehealth.org/.

Comments:
3D Vision Syndrome can be diagnosed and treated by an optometrist who has special training in disorders of the binocular vision system (how the two eyes work together). For doctors with advanced training in this area please go to the American Optometric Association (AOA), College of Optometrists in Vision Development (COVD), and the Association of Schools and Colleges of Optometry (ASCO) websites noted below.

The College of Optometrists in Vision Development (COVD) is a non-profit, international membership association of eye care professionals. COVD provides board certification for optometrists and vision therapists who are prepared to offer state-of-the-art services in developmental vision care, optometric vision therapy and visual rehabilitation.

The Association of Schools and Colleges of Optometry (ASCO) lists all schools and colleges of optometry and the faculty and reseachers who can also diagnose and treat 3D Vision Syndrome.

Over the past couple of months, I've had the pleasure of working with members of the 3D@Home Consortium, educators, the AOA members, COVD members and optometry school faculty/researchers as a part of the 3D in the Classroom AOA Project Team. Watch for some exciting information about the use of 3D in the classroom soon!

Illinois optometry college and CPS help students to focus on schoolwork

....Beginning in January, the recently closed Princeton Elementary School, in the city’s Fuller Park neighborhood, was reopened as an optometry clinic for CPS students. Classrooms in the former South Side elementary school now function as examining rooms, complete with eye charts hanging from the chalkboards and patient chairs where desks used to be. Each morning, the hallways serve as waiting rooms, filled with anywhere from 20 to 60 students, anxiously waiting their turn.  


“From the perspective of seeing about 1,250 students, about 75 percent of the kids have actually needed glasses,” said Dr. Sandra Block, optometrist and associate dean at the Illinois College of Optometry, “Ultimately our goal is to look at this intervention as allowing kids one less barrier to do well in school.”  ....
