The American Optometric Association has taken on the task of informing its membership and the patients we serve about the binocular vision problems that can spoil the 3D movie cinematic experience.
If your focusing, eye teaming and eye movement systems are not functioning appropriately you may experience eye strain, double vision, nausea and many other symptoms. The good news is that your family optometrists can diagnose and treat these vision problems with optometric vision therapy.
The AOA was kind enough to use me as a vehicle to get the word about these binocular vision problems...they even suggested that you not only consult the AOA website but that you also use the MainosMemos blog as a resource for the latest in vision care research information.
I want to thank all of my AOA colleagues. I deeply appreciate what you do for the profession, our patients and for the trust you have placed in me to help you tell this very important story!
I would also like to suggest that those have problems with 3D movies and television also consult the College of Optometrists in Vision Development website at http://www.covd.org, the Illinois Eye Institute, and the doctors and staff of Northwest Optometric Associates. DM
Comments: I keep reminding my students that your patients are no more honest than you are when you are a patient and your doctor is asking you case history questions. Our job is not to catch our patients in a lie...but rather to make it easier for them to tell us the truth! DM
"We found fathers are more inclined than mothers to activate exploratory behavior by being less protective," says Paquette. "The less the parent is protective, the more activated is the exploratory behavior in the child. Children who were optimally stimulated, meaning they were exploratory yet respective of the rules, were 71 percent boys. Meanwhile, 70 percent of children who were risk averse were girls." ...

Eye Fatigue While Watching 3-D Movies May Signal Need For Eye Exam, Optometrist Says.
HealthDay (4/8, Gardner) reported, "An estimated 30 percent of moviegoers have enough eye coordination to see 3-D, but only with a struggle. These are the ones more likely to get headaches and eye fatigue while watching 3-D on the big screen, said" optometrist Jeffrey Anshel, OD. While "die-hard movie fans might benefit from dramamine [dimenhydrinate] or other motion-sickness medications," they "could take it as a clue that" their "eyes need a full exam, Anshel said."
It sounds very interesting.. and the job you are doing over here seems
very good. We wish to hear more updates regarding the conference and
may be you can send us the Audio Visual materials if possible. That
would be really great..So that we can present here to the optometry
students over here.
Nabeen....I'm not sure what country you are in, but I thank you for your kind comments about my blogs concerning the conference...all of you who want to know more about the ICBO/NORA 2010 2010 Conference please visit http:.//www.oepf.org, DM
One of the ICBO/NORA innovations for this meeting has been the introduction of a conference newsleter. Today's issue (Friday) gives a few highlights about yesterday's events (It discusses VS Ramachandran's excellent presentation: The Human Brain--Molecules to Metaphor")and informed the reader that Robert Williams (Exec Director OEP) is to receive the Doctor of Humane Letters degree at SCO's graduation ceremonies). The editors of the newsletter asked a few attendees to write up their perceptions of the presentations for publication. I was asked to write about a very special presentation for publication in tomorrows newsletter edition...
I informed the powers that be that since I am not only an accomplished writer and editor that I was sure my review would be absolutely perfect as written and would need little to no editing on their part...(please note tongue placed firmly in cheek). I was informed that what I wrote might need some editing after all, however....so I am publishing for your reading pleasure the full, unedited and unabridged review.
If you like it....tell the powers that be I was right....if you don't like it...tell me, I want to know who you are!!! (;-)>
A Distant Memory: Near to the Heart
Dominick M. Maino, OD, MEd, FAAO, FCOVD-A
The J Field Foundation website (http://www.jfieldfoundation.org/) notes that: "A near-fatal car accident left Jennifer Field with a traumatic brain injury at the age of 17. Through the autobiographical one-woman show “A Distant Memory” Jennifer shares her journey of hope and recovery." Her performance of “A Distant Memory” at the International Congress of Behavioral Optometry and the Neuro-Optometric Rehabilitation Association joint meeting confirmed attendees already strongly held opinion that we must continue to learn about and help those with TBI.
She came on stage with a halting walk. She sat stiffly on a stool. Back straight, eyes straight. She began to speak. She said, “I am not an alcoholic, drug addict, or mentally impaired.” Her speech was slightly hesitant with a “ouw” sounding tone integrated in to her speech that you might associate with any of those noted in her opening commentary.
She used video to show her skills as an accomplished equestrian. Then you hear the sound of a car crash. And she told her story of the accident…the sounds, lights, and the cessation of breathing…
I was sitting right in front and when she played music during her presentation our eyes met briefly and she smiled… The smile was asymmetrical….it was obvious that she had worked very hard to retrieve that smile from a different time
Videos of Jennifer’s mom were used extensively. Optometrists work with moms just like hers all the time. We understood this mom, her love and concern. She went on to describe the acute care scene and her early care as a non-responsive patient. The family was asked to bring in familiar objects to interact with her….even horse manure. (Remember she was crazy in love with horses!)
Finally she was able to open an eye. Finally she could say her name…in a gentle whisper….and her true rehabilitation journey began…. After transferring to the Rehabilitation Institute of Chicago, she worked hard and eventually went home. She tried to ride again, but couldn’t handle the horse the way she had in the past. Her boy friend drifted away. She learned that roller-blading was not a good idea. She learned that relationships can still hurt. She learned she didn’t “need” to be taken care of…but it would be OK if a “strong, sensitive, handsome genius” wanted to take care of her.
Jennifer discussed the many therapies she had utilized….including yoked prisms and contact lenses prescribed Dr. William Padulla. Her distorted world was less distorted. Her gait improved and her diplopia was eliminated. Life was better.
Jennifer graduated Magna Cum from Wheaton College and is an accomplished painter, poet, and actress… and now her story continues.
Unlike many doctors, researchers and others in health care, behavioral optometrists do not need to be reminded why we do what we do every day. We do it for all the Jennifer’s and all the moms. We do it so that Jennifer’s story is not a solo…but a chorus singing of their many successes in living a life of consequence. We do it not because this is our job, but our profession.

A film can certainly be enhanced by 3D. It is a whole new sensory experience and that is a good and bad thing. Because the film is inconsistent with real life, it can lead to feeling tired. ...
In the real world, a person's eyes converge when they look at nearby objects and diverge when they look into the distance. At the same time, a person's eyes have to focus....

I just spent this morning with more than 500 colleagues from around the world listening to VS Ramachandran, MD, PhD discuss neuroscience and neuro-rehabilitation. He is a remarkable individual with a great lecture style....and presents the most interesting information that is that supports what behavioral optometry has been doing for decades. The ICBO/NORA 2010 has already met all my expectations....and we are not done until Sunday! DM

Comments: I wonder what would have happened if optometric vision therapy was used to treat these patients? Since myopia development appears to be linked to retinal defocus, blur, accommodation and the heterophoria....it would be a great project to see what would happen if OVT treated these areas and its affects on myopia development.

V.S. Ramachandran is Director of the Center for Brain and Cognition and Professor with the Psychology Department and Neurosciences Program at the University of California, San Diego, and Adjunct Professor of Biology at the Salk Institute. Ramachandran’s early work was on visual perception but he is best known for his experiments in behavioral neurology which, despite their apparent simplicity, have had a profound impact on the way we think about the brain.
Ramachandran has published over 180 papers in scientific journals. He is author of the acclaimed book “Phantoms in the Brain” NEWSWEEK magazine has named him a member of “The Century Club” – one of the “hundred most prominent people to watch in the next century.”
Jennifer Field was 17 when a car accident left her comatose and severely brain injured. Few expected her to survive. But she did. Fewer expected any kind of recovery. Now, she travels the country, performing a one-woman show, re-living her story so that others who’ve suffered traumatic brain injuries never lose hope.
Comments: Jennifer is one of the Keynote speakers at this year's International Congress of Behavioral Optometry and Neuro-Optometric Rehabilitation Association join meeting this week in California. Hope to see you there! DM
Maino D, Schlange D, Donati , Bakouris C, Nikoniuk M. A Gun Shot to the Head: Oculo-Visual & Perceptual Anomalies. Peer reviewed poster presented at the International Congress of Behavioral Optometry. Ontario, CA 04/2010
Traumatic brain injury (TBI) results from mild, moderate or severe trauma to the head. The use of firearms, motor vehicles and falls causing the most deaths from TBI with firearms being the leading cause of death among persons aged 20 to 74 years. The CDC estimates that 5.3 million Americans (2% of the US population) have suffered a TBI. More than 1.4 million people a year sustain a TBI with 50,000 of these individuals dying and 235,000 being hospitalized.
CASE REPORT: A 25 y/o H M with a history of a gunshot to the right side of the head presented with left side spasticity, hemianopsia, diplopia, problems tracking a moving object and reading difficulty. AO had completed a post TBI rehabilitation program (OT, PT, Speech/Lang), but still has PT 2X a week. His current medications include Phenytoin, Sertraline, Kepra and Baclofen. AO had no known allergies. He had a small amount of myopia and astigmatism. An exotropia with left hyper was noted at far/near. Other functional vision and vision information processing problems were noted as well. The fundus was remarkable for temporal ON pallor. His final diagnosis was exotropia, hypertropia, diplopia, suppression, oculomotor dysfunction, accommodative instability, dry eye, optic nerve pallor, left emianopsia, visual attention disorder nd multiple vision information processing anomalies. A multifocal prescription was given with both ground in and Fresnel prisms. Artificial tears and Omega-3s with appropriate hydration were suggested for the dry eye. In/out of office optometric vision therapy program was started. He showed many of the oculo-visual anomalies associated with Post Trauma Vision Syndrome. We have decreased his dry eye symptoms, eliminated his diplopia and significantly improved his oculomotor abilities. Because of this, his reading and quality of life has already improved. Unfortunately after several visits he decided not to continue therapy primarily because of transportation issues and possible non-acceptance of his limitations. All individuals with TBI should be assessed and treated by an optometrist who may be able to provide additional rehabilitative services beyond those routinely offered by the medical community.
The mom (blogger, foundation president, wonderful person) who practically single handedly saved the vision of Illinois' children wrote a great review of the movie How to Train Your Dragon 3D. Janet Hughes writes on her blog:
Amazing. Incredible. Out-of-this-world!
Advocating for healthy eyes and good vision took a new turn… into 3D!
“How to Train Your Dragon” earns FIVE STARS from me. If you haven’t seen a 3D movie yet, THIS is one movie not to be missed!
Unfortunately, nine to eighteen million Americans will NOT enjoy a 3D movie due to undetected vision problems.
Amblyopia (lazy eye), strabismus (eye turns), and binocular vision disorders (such as CI or convergence insufficiency) will hinder the visual experience of a 3D movie.....
