Healthbeat Report: The 3-D Dilemma


Chicago-lands ABC WLS TV news just finished showing a HealthBeat segment where I was interviewed on the "Avatar 3D Vision Syndrome" during the 10 PM time slot. Here is a bit of the transcript....click on the title above for the full transcript and video....(Photo by Waldo Duran...thanks Waldo!)

February 25, 2010 (CHICAGO) -- Digital technology is making the 3-D experience like nothing before. But many people still say trying to see in stereo leaves them with a headache, stomach ache or both. That could be a sign of an undiagnosed vision problem. And there may be a way to fix it.

For decades, 3-D was seen as more of a gimmick than an art form. Today's three-dimensional experience is challenging that perception. And by spring you could have a 3D TV in your home.

But even in this advanced form3-D is leaving some viewers feeling sick. Angela Brusnman is one of them.

"Throughout the experience it's definitely an ocular headache. You can tell it's definitely coming from right behind the eyes," said Brunsman.

Complaints include headache, nausea, dizziness and fatigue. There are no hard numbers but its estimated anywhere from 4 to 10 percent of the population can't watch or tolerate 3-D.

"Anywhere from 3 million to 9 million or more will have binocular vision dysfunctions that will stop them from enjoying 3-D movies," said Dominick Maino, O.D., optometrist, Illinois Eye Institute.".....


I went on to discuss how we can treat those binocular vision disorders that stop my patients from enjoying 3D movies....

The newscast also interviewed an Ophthalmologist, who did not think optometric vision therapy would help adults...it's too bad he has not stayed up to date on all the new neuroplasticity research that clearly shows even adult brains can change in a positive fashion with the right therapy!! I'll post the link to the video as soon as it becomes available.

Untreated Vision Problems In Elderly Associated With Increased Risk Of Cognitive Decline.

From AOA News:

MedPage Today (2/23, Bankhead) reported that, according to a study published online in the American Journal of Epidemiology, "untreated vision problems in older age are associated with an increased risk of decline in cognitive function and Alzheimer's disease." In a study of "625 participants followed for an average of 10 years," researchers found that "uncorrected poor vision was associated with a five- to 10-fold greater risk of Alzheimer's disease and a five-fold greater risk of cognitive decline without dementia, compared with older people who had very good or excellent vision."

Reuters (2/24, Norton) reports that while it remains unclear why untreated vision problems contribute to dementia, one study author theorized that poor vision may prevent some seniors from fully taking part in a social life, exercising, reading, and performing activities to keep their minds active, all of which could help stave off dementia.

Help with IEP and 504 Plans

I just had a parent write me saying:

Are you aware of a comprehensive list that suggests possible 504 plan/IEP accommodations for each separate visual processing diagnosis area? I am part of a parent networking group and many of our families have children with visual processing diagnoses. However, when they approach the school for a 504 plan, they find themselves needing to 'educate the educators'! As such, it would seem beneficial to have a list of specific accommodations that might be applicable to each diagnosis, rather than walking in with a three page list of possible accommodations and overwhelming the school team. Many standard accommodations most likely apply to most/all of the diagnoses, but perhaps there are some that apply to only certain diagnoses.

Thank you for your time and for your many valuable contributions to 'education & awareness' regarding visual processing. Our daughter's world changed dramatically when we finally got her diagnosed and treated appropriately for convergence insufficiency/binocular dysfunction. The world is a MUCH less frustrating place for her now!


So here's the list we use at the Illinois Eye Institute. This may be a good starting point.

Area Adjustments

Gross Motor Encourage individual motor activities
Select games/activities that ensure success

Laterality / Directionality Label directions on paper
Point to the direction when giving instructions

Allow use of finger, pointer, or highlighter
Point out / highlight important features
(See suggestions under visual discrimination)

Visual Closure Point out significant features
Allow tracing of forms with finger prior to copying

Visual Memory / Allow use of aids (i.e. mnemonics)
Visual Sequential Memory Reinforce visual information with other sensory aids
Reduce the number of steps in visual tasks

Visual Motor Integration Reduce time on written work
Allow oral or taped responses
Use large diameter pencils
Allow boundaries for printing
Color code materials
Allow tracing of forms prior to copying

Auditory-Visual Integration Stress single modality (auditory or visual – not both at the same time)

Amazing 3D Photography by Almont Green


I just received an email from a wonderful photographer who specializes in 3D photography. He has developed a keen interest in binocularity and stereopsis because of this. His FAQ notes that....

Almont Green uses lenticular lens technology to create a real three-dimensional photograph. His multi-perspective images come from reality, a true photographic image – not from inside a computer. To date, lenticular has been used primarily for winking-eye-type animations and cut-up, stacked images created with computer software. Years ago, there were multi-lens film cameras but their fixed (and low quality) lenses limited the quality and precise alignment required for accurate “what you see in real life” recreation. Some people are experimenting with a single camera solution that moves along a rail, but this process is limited to objects that don’t move and is analogous to closing one eye and moving your head from side to side. Almont’s process is unique and his photos go beyond “museum quality”. Their limited-run availability makes them appropriate for collectors. As you move one of Almont’s photos,the images stay stable and the level of depth is so palpable,people often turn them over to see if the object is sticking out the other side.

Click on the title above to check out his website and click here to go to his blog. I am also going to list his blog here under "Blogs of Interest" on the right hand side of this blog. DM

Is There a “Language of theEyes”?

Is There a “Language of theEyes”? Evidence from Normal Adults, and Adults with
Autism or Asperger Syndrome

Previous work suggests that a range of mental states can be read from facial
expressions, beyond the “basic emotions”. Experiment 1 tested this in more
detail.... Results indicated that:
(1) Subjects show remarkable agreement in ascribing a wide range of mental
states to facial expressions, (2) for the basic emotions, the whole face is more
informative than either the eyes or the mouth, (3) for the complex mental states,
seeing the eyes alone produced significantly better performance than seeing the
mouth alone, and was as informative as the whole face. In Experiment 2, the
eye-region effect was re-tested,... Results were broadly similar
to those found inExperiment 1. InExperiment 3, adults with autism orAsperger
Syndrome were tested using the same procedure as Experiment 1. Results showed
a significant impairment relative to normal adults on the complex mental states,
and this was mostmarked on the eyes-alone condition. The results fromall three
experiments are discussed in relation to the role or perception in the use of our
everyday “theory of mind”, and the role of eye-contact in this.

Differential development of visual attention skills in school-age children

...Children aged 7–17 years and adults aged 18–22 years were tested on three aspects of visual attention: the ability to distribute visual attention across the field to search for a target, the time required for attention to recover from being directed towards a target, and the number of objects to which attention can be simultaneously allocated. The data suggested different developmental trajectories for these components of visual attention within the same set of participants. This suggests that, to some extent, spatial, temporal and object-based attentional processes are subserved by different neural resources which develop at different rate. In addition, participants who played action games showed enhanced performance on all aspects of attention tested as compared to non-gamers. These findings reveal a potential facilitation of development of attentional skills in children who are avid players of action video games. As these games are predominantly drawing a male audience, young girls are at risk of under-performing on such tests, calling for a careful control of video game usage when assessing gender differences in attentional tasks.

Helping people see in 3-D



From the Herald Citizen.... "Your peripheral vision is connected very intimately with your balancing system," said Dr. Jason Clopton, developmental optometrist and director of the Center of Vision Development in Cookeville. "When you get a lot of information in your peripheral vision -- like on a big screen -- and a lot of movement, it may give you this sensation that you're physically moving when you're not. If the two systems are working together, you shouldn't have any difficulties at all." A movie in 3-D works by projecting two images on the screen, with each image seen by one eye. The images are then merged into one by your brain. If the images aren't perceived correctly, it will be difficult to merge or fuse them into 3-D....

The Early Course of Autism

...There has been much debate about the early course of autism, specifically the earliest age at which autism may be detected. At present scientific evidence suggests that autism is dominantly genetic, and so researchers expect that there may be early signs of autism even in infancy. Traditionally, however, autism is not diagnosed until age 2-3, when parents bring their children to medical attention, or when signs are detected on routine well-child visits or in day-care....

Oxytocin Touted As Autism Treatment

...in the study, adults with autism or Asperger's disorder received an intravenous infusion of pitocin (synthetic oxytocin) or placebo (saline solution) over a four-hour period. During that time, participants were monitored for repetitive behaviors that are hallmarks of autism spectrum disorders including need to tell/ask, touching, and repeating. These behaviors were assessed at a baseline and throughout the course of the infusion. "Repetitive behaviors are often overlooked as symptoms of autism in favor of more dramatic symptoms like disrupted social functioning," explained Hollander. "However, early repetitive behavior is often the best predictor of a later autism diagnosis."

The study found that the infusion produced results that were both clinically and statistically significant. Hollander noted a rapid reduction of repetitive behaviors over the course of the oxytocin infusion, whereas no such reduction occurred following the placebo infusion. ...

Hormone-infused nasal spray found to help people with autism

...The study, involving 13 adults with either a high-functioning form of autism or Asperger syndrome, a mild form of the disorder, found that when the subjects inhaled the hormone oxytocin, they scored significantly better on a test that involved recognizing faces and performed much better in a game that involved tossing a ball with others. ....

Placebos Advocated as Active Treatments

...The placebo effect is a real and therapeutic psychological phenomenon that, with more research, could be exploited more systematically in medical practice, said Australian researchers....

Parent Writes about Child with IAXT

I recently received a comment on one of my posts where a parent writes about her infant with an intermittent alternating exotropia (eye turn out). The ophthalmologist says surgery is the only cure. The optometrists wants to do patching and other non-surgical intervention. The parents do not want surgery and asks me for advice. This blog does not give medical advice and all who read this should consult their own doctors about what to do. Since I have not examined this little one I really do not want to make any specific suggestions.

Here's what I would suggest for a hypothetical patient however, if the following were true and varified by my examination results:

The eye turn is relatively infrequent.
No neurological or pathological (disease) etiology has been found.
No major refractive error is found (no large amounts of nearsightedness, farsightedness, astigmatism)

I would suggest to these hypothetical parents to:
1.) Watch the child closely and keep a log where you would write down how often the eye turns during the day, which eye, and for how long. This would give us a better idea of the frequency of the eye turn.
2.) If the eye turn in infrequent, I would monitor the child closely or prescribe prism to allow the visual system to develop binocularity (two eyed fusion) as much as possible.
3.) If one eye turns in more frequently than the other, I would have the parents patch the eye used most often while engaging the child in handeye activities. I would monitor this very closely so I do not make the better seeing eye amblyopic.
4.) If both eyes alternate fixation equally, again I would monitor and give the child prism glasses to help fusion develop.
5.) If one eye turned in all the time, I would patch the other eye while engaging in active therapy. I would monitor this closely and again use prism glasses.

Although strabismus surgery usually results in good outcomes if the surgery is done early, these outcomes seem to occur even if done when the child is older. Please remember surgery is not the cure some ophthalmologists may tell you it is. If you've been reading this blog, you know surgical outcomes vary greatly for each patient and over time.

I am concerned that no cause has been found for the eye turn. I would definitely look deeper in the XTs etiology.

Remember this blog and I do not give medical advice. Talk to your doctor. Get a second opinion. Visit http://www.covd.org for doctors who have expertise in this area. Good Luck. DM
