KGW investigation: LensCrafters selling used glasses as new?

...It's the nation's largest optical store chain, and it had a secret.

At least until KGW obtained an internal company memo.

Turns out those expensive new glasses you just purchased might have already been worn by another customer.

Dr. Robert Forbes has just started a new optometry practice in Happy Valley, but for more than a decade, he leased office space from the LensCrafters store inside Clackamas mall. He says he left because of what he calls distasteful new business practices inside LensCrafters....

Comments:This is unacceptable. All patients should go to practices they know and trust. DM

What's New in Autism Research from Pubmed

Here's what's new. Go to PubMed to get the full abstract.

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.



Allen MLBrief report: decoding representations: how children with autism understand drawingsJ Autism Dev Disord. 2009 Mar;39(3):539-43. Epub 2008 Sep 23.

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.

D.M.Riby@newcastle.ac.uk

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.

Faja S, Webb SJ, Merkle K, Aylward E, Dawson G. Brief report: face configuration accuracy and processing speed among adults with high-functioning autism spectrum disorders.J Autism Dev Disord. 2009 Mar;39(3):532-8. Epub 2008 Aug 27.

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. ....

Ageing Brains Show Great Promise For Rejuvenation

...In research published in Stem Cells, Dr Daniel Blackmore and his colleagues at the Queensland Brain Institute (QBI) have shown that moderate exercise directly increases the number of stem cells in the ageing brain. ...

Comments: Ok...it REALLY is time for me to get away from this dang computer and start moving about!! DM

Changes In Brain Architecture May Be Driven By Different Cognitive Challenges

...Scientists trying to understand how the brains of animals evolve have found that evolutionary changes in brain structure reflect the types of social interactions and environmental stimuli different species face...

Comments: Environment plays a role in brain development and evolution. I thinnk optometry has known this for some time. DM

Brain Plasticity: Changes And Resets In Homeostasis

...In an article published in the June 25th edition of the journal Neuron, researchers at the Hotchkiss Brain Institute, University of Calgary, have found that synaptic plasticity, long implicated as a device for 'change' in the brain, may also be essential for stability. ...

Could Estrogen Improve Outcomes After Traumatic Brain Injury, Shock?

...UT Southwestern Medical Center researchers are conducting two pilot clinical trials to determine whether a single, early dose of estrogen can improve survival and neurological outcomes after severe traumatic brain injury or traumatic hemorrhagic shock...

American Optometric Association Approves Optometric Board Certification At Annual Meeting

..."Our members' actions Friday suggest that optometrists see the need for a mechanism to clearly demonstrate continued competency to patients, legislators and payers," said Randy Brooks, O.D., president of the AOA. "The creation of the American Board of Optometry will provide a unified national platform to establish and demonstrate competency and value and will position our profession solidly for the future." ...

Neurological Differences Support Dyslexia Subtypes

...Parts of the right hemisphere of the brains of people with dyslexia have been shown to differ from those of normal readers. Researchers writing in the open access journal BMC Neuroscience used magnetic resonance imaging (MRI) to compare the two groups, and were able to associate the neurological differences found with different language difficulties within the dyslexic group. ...

Further Gene Mutations Linked To Autism Risk

...Pieces in the complex autism inheritance puzzle are emerging in the latest study from a research team including geneticists from the University of Pennsylvania School of Medicine and The Children's Hospital of Philadelphia (CHOP). The study identified 27 different genetic regions where rare copy number variations - missing or extra copies of DNA segments - were found in the genes of children with autism spectrum disorders, but not in the healthy controls. The findings are published June 26 in the open-access journal PLoS Genetics....

UC Davis Researchers Develop New Test For Fragile X Syndrome

...Researchers at UC Davis have developed a new test that will measure the protein deficit responsible for fragile X syndrome - the single-most common cause of intellectual impairment and the most-commonly inherited cause of autism...

ADHD Genes Found; Known To Play Roles In Neurodevelopment

...Pediatric researchers have identified hundreds of gene variations that occur more frequently in children with attention-deficit hyperactivity disorder (ADHD) than in children without ADHD. Many of those genes were already known to be important for learning, behavior, brain function and neurodevelopment, but had not been previously associated with ADHD....

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

More success stories for my former students!













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


My students' Success!


When my students succeed in life, I like to think that I might have had a small part to play in that success. Drs. Patricia and Angelica Perez are doubly successful....as great optometrists and twins! Both were featured as the cover story in Women in Optometry , a supplement to the Review of Optometry this past June. Patricia and I also serve on ICO's Alumni Council. My congratulations to both!

Many of you know this, but I am also a very proud optometric twin. My brother Joseph is Chief of Optometry at the Kansas City, VA Hosptial. He is a low vision specialist so even though we deal with different aged populations...we both strive to increase vision function in our patients. If there are any other optometric twins out there, let me hear from you. DM

Characteristics of associated craniofacial trauma in

...Adult males are the most common victims in craniofacial trauma, and road traffic accidents were responsible for the majority. Most of the patients sustained mild head injuries and were managed conservatively. Open reduction and internal fixation with miniplates was used for displaced facial bone fractures....

Fixing My Gaze Reviewed in New England Journal of Medicine

My good friend and colleague, Dr. Len Press sent this to me:

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

Thriller



Thriller by MJ. Good song. Strange fellow.

Corneal Power and Astigmatism in Down Syndrome.

... The majority of the DS group have significant refractive errors including an increased prevalence of oblique astigmatism. Corneal curvature in DS is not related to spherical (M) or astigmatic (J0, J45) refractive error. Further research is required to better understand the association between the ocular structures of the DS eye and their impact on functional vision....
