Stravinsky taken to another dimension: The 3rd Dimension!

....Symphony Hall will never before have seen audiences like it in all its 20 years, when next Thursday we will all be wearing 3D glasses to experience a 21st-century digital makeover of Stravinsky’s groundbreaking ballet The Rite of Spring.
Nine stereoscopic cameras, simulating human binocular vision, will be focusing on the movements of the acclaimed contemporary dancer Julia Mach, as she interprets the score. Fed into a complex computer system, the images will be generated into 3D on a giant silver screen positioned above the CBSO conducted by Ilan Volkov, all delivered into our faces – and all in real time......

3-D SCRUTINY

....The new Nintendo 3DS game system includes a warning that its 3-D screen shouldn't be used by children 6 or younger because it may harm their immature vision.But eye specialists say they don't expect any harm. Some optometrists even see potential benefit for young kids, saying a child's reaction to a 3-D screen use might help uncover vision disorders that have to be caught early to be fixed. But ophthalmologists say there's no evidence of benefit.....

The 3Ds of Stereoscopic 3D Viewing

The 3Ds of Stereoscopic 3D Viewing


•Discomfort:

Since 3D viewing is based on the eyes converging in front of or beyond the screen, viewing 3D images can potentially create eyestrain and headaches. Consumers can reduce the conflict by sitting at a greater distance from the screen.

•Dizziness:

3D technology can exaggerate visual motion hypersensitivity (VMH), which can cause motion sickness, and vergence-accommodation conflict, causing consumers to feel dizzy or nauseous during or after viewing 3D content.

•Lack of Depth:

A viewer lacking binocular vision, simply won’t see 3D. While this doesn’t pose any problem viewing the screen, it serves as a “vision screening” that something is abnormal with the viewer’s binocular vision.

Rehab For The Brain After Traumatic Injuries

.....The remaining 85 percent of people who experience a TBI will experience a mild injury. Often, the terms "mild TBI" and "concussion" are used interchangeably. These individuals typically experience alterations in their neurological state after injury (e.g., mental confusion, headaches, dizziness, visual changes, etc.) and are evaluated in an emergency room or a local doctor's office. Of these individuals, approximately 85 percent recover fully over the next several weeks to months. Approximately 15 percent of those with mild TBI, however, will experience ongoing physical, cognitive and emotional changes similar to those with more severe TBI. These individuals typically are referred to an outpatient TBI rehabilitation setting for assessment and treatment. The goal of their treatment is to maximize their functioning with the aim of returning to work, school and former community roles.....

Why Does Brain Development Diverge From Normal In Autism Spectrum Disorders?

..... "Many ASDs manifest between 1 and 2 years of age, a period when kids are interacting more with the outside world," ..... "The brain of an autistic child looks normal, but there's a subtle difference in connections that has to do with how they process experiences. If you could diagnose early enough, there might be a way to alter the course of the disease by modifying experience, such as through intense one-to-one therapy." ...... focused on a synaptic circuit in the brain's visual system that is relatively easy to study, known as the retinogeniculate synapse. It connects the cells receiving input from the eye to the lateral geniculate nucleus, an important relay station in the brain's thalamus. Visual inputfrom the outside world, during a specific "critical period," is crucial for its normal development......

Optometry & Vision Development, Volume 42, Number 1 Available Online Full-Text

College of Optometrists in Vision Development (COVD) Journal
Optometry & Vision Development
Volume 42, Number 1 Available Online
Full-Text, Free of Charge to All

AURORA, Ohio, April 18, 2011 /PRNewswire-USNewswire/ -- The College of Optometrists in Vision Development (COVD) has posted its current issue of Optometry & Vision Development online and invites all to read the full-text articles free of charge.

The journal of the College of Optometrists in Vision Development, Optometry & Vision Development (OVD), Volume 42 Number 1 offers articles concerning clinical research on children with visual impairment and their focusing ability; an assessment of visual processing disorders within families; and how to use an instrument designed for one purpose and adapting it to assess how efficiently the eyes move.

OVD editor, Dr. Dominick M. Maino notes that, "You'd think eye care professionals would know that children with macular pathologies and in need of Low Vision specialty lenses would take into account accommodative demand (focusing) when prescribing for near. Unfortunately, all too often they do not." Catherine L. Heyman, OD, FAAO, FCOVD; assistant professor at the Southern California College of Optometry and author of the article, Accommodative Response in Children with Visual Impairment, finds it is necessary to consider using dynamic near retinoscopy to assess each patient's accommodative response prior to prescribing near addition lenses. Using the Grand Seiko WV500 autorefractor, each subject's accommodative response was measured. Her subjects had accommodative responses of various sub-types. These included the "negative slope lag," "fixed lag," "fixed accurate," "positive slope lag" and the "fixed lead" sub-types. Each individual would require a different use of near point lenses for maximum efficiency and to improve their quality of life.

In the article, Evidence for Familial Link in Visual Processing Disorders, faculty from the Michigan College of Optometry at Ferris University demonstrated a potential link between heritability of visual processing disorders and hair color. Drs. Sarah Hinkley and Paula Smith concluded in the article that "There appears to be significant associations between the scores of family members on visual processing tests, however, the role of environment cannot be ruled out as a factor." Will it be possible to determine which children may be at risk for vision information processing/visual perception problems by hair color? Since additional research in this area is required, we cannot say so at this time. We know appropriate vision information processing is vital to academic achievement and overall school performance; if a link is found between hair color and VIP this might lead to improved screening methods for children with learning related vision problems.

OVD's article, The VisionPrint System: A new tool in the diagnosis of ocular motor dysfunction, evaluates using the Essilor designed VisionPrint System (VPS) to objectively measure the individual's head to eye movement ratio (H/E). This information is then used to determine the physiological needs of those with presbyopia. Optometry student, Janna Iyer, Drs. Marc B. Taub and WC Maples of the Southern College of Optometry found that: "The VPS can effectively be used to assess ocular motor function" and that "Since excessive head movement is a sign of ocular motor dysfunction, the VPS can assist practitioners in assessing eye/head movements, leading to a diagnosis of ocular motor dysfunction." This means that a tool initially designed for one purpose may have multiple uses within the optometrist's office.

Can a piece of string actually be the latest in technology? In his editorial, Brock String Debuts at 2011 Consumer Electronics Show, Dr. Dominick M. Maino, Professor of Pediatrics/Binocular Vision at the Illinois College of Optometry, and OVD Editor, tells how a simple piece of string can be used to diagnose and treat binocular vision problems that interfere with enjoying 3D entertainment and classroom learning. In the editorial Dr. Maino states, "3D. There's an app for that. It's called Optometric Vision Therapy," which means many of those with problems appreciating the 3D experience can be helped by vision therapy. He also noted, "Unlike that other eye-care profession that tells consumers not to view 3D if it makes them uncomfortable; we are not the Doomsday docs of 3D. We want 3D to succeed so that all can enjoy an improved vocational, recreational and educational experience."

Also included in this edition of OVD are our regular features: current literature review, practice management articles, book review, and our NewsMakers column.

What Our Eyes Can't See, The Brain Fills In

.....The results show that our brains do not rely solely on what is shown to the eyes in order to 'see'. Instead the brain constructs a complex prediction. .... "We are continuously anticipating what we will see, hear or feel next. If parts of an image are obstructed we still have precise expectation of what the whole object will look like. ..."When direct input from the eye is obstructed, the brain still predicts what is likely to be present behind the object by using some of the other inputs to come up with best 'guesses'......

PIDS releases position statement on immunization exemptions

...The Pediatric Infectious Diseases Society recently issued a position statement that “opposes any legislation or regulation that would allow children to be exempted from mandatory immunizations based simply on their parents’, or in the case of adolescents, their own, secular personal beliefs.”....
“Hundreds of thousands of deaths have been prevented through routine immunizations and tens of billions of dollars have been saved, making childhood immunizations one of the most cost-effective components of our public health system,” according to the position paper....
But fraudulent scientific data and surrounding media and celebrity hype has led to a pushback against vaccination, according to the statement. In some cases, this has led to a resurgence of some diseases, including the most recent measles outbreak.....“Even a small number of unimmunized individuals in a community can facilitate the spread of disease,” according to the statement. The risk for measles is 35 times greater for an exempt child than a vaccinated one, 23 times higher for pertussis and nine times higher for varicella......"

Have a piece of string? Test your 3-D vision


Have a piece of string? Test your 3-D vision by Suzanne Kantra
When the first 3-D movies started hitting the theaters, I was excited to take my kids to see them. I realized early on, though, that I was not enjoying 3-D — I just got headaches.


So I spoke to Dr. Dominick Maino, professor of pediatrics and binocular vision at the Illinois College of Optometry/Illinois Eye Institute, about my issue. It turns out I had one of the symptoms of a binocular vision problem that interfere with 3D viewing, which also include nausea, dizziness and lack of depth perception. This issue affects approximately 16 percent of people, yet few realize they have a 3-D vision problem.

Dr. Maino points out, binocular vision isn’t just about enjoying movies. Binocular vision problems can affect your ability to focus on a page when reading or a ball while playing sports, drive a car or ride a bike......
