Itier RJ, Batty M Neural bases of eye and gaze processing: the core of social cognition.Neurosci Biobehav Rev. 2009 Jun;33(6):843-63. Epub 2009 Feb 24.
Eyes and gaze are very important stimuli for human social interactions. Recent studies suggest that impairments in recognizing face identity, facial emotions or in inferring attention and intentions of others could be linked to difficulties in extracting the relevant information from the eye region including gaze direction. ......We suggest impairments in processing eyes and gaze may represent a core deficiency in several other brain pathologies and may be central to abnormal social cognition.

Young typically developing children can reason about abstract depictions if they know the intention of the artist. Children with autism spectrum disorder (ASD), who are notably impaired in social, 'intention monitoring' domains, may have great difficulty in decoding vague representations. ..... Results are discussed in terms of intention and understanding of visual representation in autism.
Riby DM, Hancock PJ.Do faces capture the attention of individuals with Williams syndrome or autism? Evidence from tracking eye movements. J Autism Dev Disord. 2009 Mar;39(3):421-31. Epub 2008 Sep 12.
The neuro-developmental disorders of Williams syndrome (WS) and autism can reveal key components of social cognition. Eye-tracking techniques were applied in two tasks exploring attention to pictures containing faces. ...... The findings are interpreted in terms of wider issues regarding socio-cognition and attention mechanisms.

The present study investigates the accuracy and speed of face processing employed by high-functioning adults with autism spectrum disorders (ASDs). ..... Results suggest adults with ASD were less accurate, but responded as quickly as controls for both tasks. ....
Comments: Ok...it REALLY is time for me to get away from this dang computer and start moving about!! DM
Comments: Environment plays a role in brain development and evolution. I thinnk optometry has known this for some time. DM
Comments: Just a reminder....all things start in the genes....how they end up often is determined by the environment. If we arrange the environment correctly, we can change, alter, improve the life of kids and adults with ADHD. DM
I've been a member of the Northwest Optometric Associates professional staff for decades now. I've always practiced in a private practice setting through out my career to make sure I kept at least one foot in the real world of optometry while spending most of my time in academia researching, writing, lecturing and teaching in our Illinois Eye Institute's various clinics. I've always had an ICO student working besides me as well. I figured I must have done a pretty good job of teaching because now one of those former students, Dr. Denice Rice-Kelly is my boss on Wednesdays when I'm in the office.
My congratulations to Dr. Rice for being recognized in Women in Optometry (scroll down for story). She is not only an awesome individual who manages the demand of a full time office and family, but also conducts research for major contact lens and spectacle lens companies around the world. If there is any out there who would like a role model to emulate, Dr. Denice Rice-Kelly is an individual of note. DM

From today's issue of the New England Journal of Medicine (7-2-09), an unqualified and ringing endorsement of Sue Barry's book, and of specially trained and imaginative optometrists which reads, in part:
"Capitalizing probably more on latent neuronal connections than on the creation of new ones, Barry benefited from orthoptics — a hidden corner of restorative medicine. With contrived ocular exercises, specially trained and imaginative optometrists treat patients whose eyes are cosmetically aligned but imperfectly foveated. The simplicity of the exercises and of the apparatus (such as beads on a string, papers taped to walls, and strips of film) is bracing for a profession enamored with technology.
The book’s main contribution, however, is exposing the wrong-headed dogma that acuity and binocular vision can be restored only during a critical developmental period. Surgical correction of strabismus is dominated by this notion, first posited by Claud Worth in his landmark 1903 book, Squint: Its Causes, Pathology, and Treatment, and set at a hard stop at 2 years of age by his student Francis Chavasse. The experiments of Hubel and Wiesel are often cited as confirming the lost malleability of the adult brain, but Barry points out that they did no such thing because there was no attempt at restoration of fusion. Her experiences and those she recounts from others belie the “nothing else can be done” message that ophthalmologists gave to her and to her mother throughout her childhood.
Several visual scientists have now demonstrated the reversibility of infantile loss of vision and stereopsis, but blindness to these findings and underappreciation of the solutions offered by orthoptics still persist."
Comments: I have to laugh....at least a little. Optometric vision therapy has never been hidden from our Ophthalmology colleagues....but they (OMDs) have deliberately and continually closed their eyes (and minds) to the possibility that what we have been doing for decades is therapeutically sound and can change how we see.
I also have to laugh at "With contrived ocular exercises, specially trained and imaginative optometrists treat patients whose eyes are cosmetically aligned but imperfectly foveated. The simplicity of the exercises and of the apparatus (such as beads on a string, papers taped to walls, and strips of film) is bracing for a profession enamored with technology. " Our therapeutic programs (definitely not ocular exercises) are not contrived but well thought out. We also straighten out turned eyes.....and it is the simplicity of some of our therapeutic procedures that make them so effective. Although we often use computers as a part of our therapy program....we also use what has been shown to work from our past.
Also research in neuroplasticity has shown that new neuro-pathways are often created...not just the re-activation of old ones...( see Maino D. Neuroplasticity: Teaching an Old Brain New Tricks. Rev Optom 2009. 46(1):62-64,66-70. (Tested Continuing Education Course))
It is about time for our Ophthalmological colleagues to stop their dedicated ill will towards the profession of Optometry. We are not going anywhere. We examine and take very good care of our patients. We are the primary eye care providers to the United States and its people. Get over it. Move on. Let's work together for the benefit of our patients. You do the surgery. We do everything else...including optometric vision therapy. DM

Comments: Finally spectacles are getting their due. When we prescribe a pair of spectacles....this is VERY important...we stop people from being blind. We save sight. We are awesome! (At this point my wife ususally says something like..."If you don't quit patting yourself on the back you are going to break your arm!!). DM
Comments: Children labeled cotically blind often are not blind at all. Something else is going on. DM
Comments: Although this tells how to write for a medical journal....writing is writing...read this, do it....if what you write is on pediatrics, binocular vision, strabismus, amblyopia, optometric vision therapy, etc....email it to me and we'll put it into the peer review process for Optometry & Vision Development...if it's on other topics send it to the AOA, AAO and other find organizations with journals...see it, do it, write it! It's that easy (and that hard). DM
Comments: For full text of article, click on title above. DM
The use of refractive surgery – LASIK, PRK and even lens exchange – in pediatric patients is relatively new. While some investigators suggest theoretical benefits, others contend that either there is insufficient data to date to support its widespread adoption or the studies to date have been improperly constructed to decipher feasibility. ...
Comments: What are they thinking? Refractive surgery for children? For the vast majority...maybe all...we should not allow this to happen. In my opinion...it most cases this should be considered a form of child abuse. What is going to happen to that child after 20, 30, or 50 years? What very serious eye problems will develop over time. Don't do it. As is noted above...there is insufficient data to date to support its widespread adoption or the studies to date have been improperly constructed to decipher feasibility... DM
Comments: Can you imagine what you could achieve if you linked medication with optometric vision therapy? DM
Visuospatial skills, ocular alignment, and magnetic resonance imaging findings in very low birth weight adolescents
Comment: Get these children in to see a functional/behavioral/developmental optometrist as soon as possible. Active optometric visioin therapy and a bit of brain neuroplasticity should help improve vision function! DM
Comments: Amblyopia (mild to severe) can be improved at practically any age....with atropine, with active optometric vision therapy, with glasses...do it or refer to someone who will! DM
Comments: Since I play the trumpet I found this interesting. Hmmm, perhaps it's time to learn a new instrument? DM
Comments: Read her book, "Fixing My Gaze" today. A most wonderful story. DM
Comments: Functional/Developmental/Behavioral Optometry has known this for decades. MOTOR including motor activities using tools (optometric vision therapy procedures0 changes the brain which changes vision function. DM
