Space Owl: A Red/Blue Anti-Suppression Vision Therapy Game

Space Owl: A Red/Blue Anti-Suppression Vision Therapy Game


Does Dyslexia Disable Teachers?

Does 'dyslexia' disable teachers?


"...the two different labels were associated with differences in the teachers' beliefs about their efficacy in helping the children. They indicated that the label 'dyslexia' evoked responses that suggested it was seen as a fixed disability, and that the teachers believed their ability to help children with 'dyslexia was unlikely to develop over time...."

Could an insulin nasal spray help treat Alzheimer's?

Could an insulin nasal spray help treat Alzheimer's?


"Every 67 seconds, someone in the US develops Alzheimer's disease. More than 5 million Americans are living with the condition and it is responsible for around half a million deaths each year. But in a new study, researchers from the Wake Forest Baptist Medical Center in Winston-Salem, NC, reveal they may have found a promising new treatment for the disease - in the form of an insulin nasal spray...."

Autism blood test nears market

Autism blood test nears market


".....In a potentially major advance in diagnosing autism spectrum disorder, San Diego's Pediatric Bioscience is preparing to sell a blood test later this year that would detect risk of one of its most common forms.
The company's test detects antibodies in a woman’s blood that can cause what it calls “maternal autoantibody-related” autism, which the company says, based on clinical studies, represents 23 percent of all autism cases.....

Improvement in reading symptoms following botulinum toxin A injection for convergence insufficiency type intermittent exotropia

Improvement in reading symptoms following botulinum toxin A injection for convergence
insufficiency type intermittent exotropia

Comments: After "convergence exercises" were conducted, those still with symptoms were injected with Botox. Many of the subjects improved after this injection. This was a small study and "convergence exercises" were not fully described. Perhaps if they did optometric vision therapy and not convergence exercises (which may or may not have treated accommodative dysfunctions associated with the CI IXT), injecting Botox may not have been needed.

Video games as vision therapy

Video games as vision therapy

"....“The video games are designed in such a way that the weak eye views a strong target that reliably attracts attention to it to enable it to see the target,” .......“The strong eye is also presented with a target, but it is not seen by the observer because the weak eye suppresses the vision of the strong eye from consciousness.”.....

Comment: Optometrists have known that amblyopia is a binocular (two eyed) brain problem for a very long time. That is why binocular vision therapy (and not just patching alone)  is so important when it comes to treating this serious vision disorder. This is one more step moving all in the right direction when thinking about, diagnosing and treating amblyopia!

Binocular vision in amblyopia: structure, suppression and plasticity

Binocular vision in amblyopia: structure, suppression and plasticity


"....The amblyopic visual system was once considered to be structurally monocular. However, it now evident that the capacity for binocular vision is present in many observers with amblyopia. This has led to new techniques for quantifying suppression that have provided insights into the relationship between suppression and the monocular and binocular visual deficits experienced by amblyopes. Furthermore, new treatments are emerging that directly target suppressive interactions within the visual cortex and, on the basis of initial data, appear to improve both binocular and monocular visual function, even in adults with amblyopia. The aim of this review is to provide an overview of recent studies that have investigated the structure, measurement and treatment of binocular vision in observers with strabismic, anisometropic and mixed amblyopia....."

Comments: Amblyopia (aka lazy eye) has always been a binocular vision/brain problem AND can only be treated appropriately using binocular vision therapy. Amblyopia's reduction in vision is the outward sign of the problem. Using principles of neuroplasticity, you can change the brain so that the patient not only sees better, but also has better depth perception (3D vision) which is important to maintain the better visual acuity AND ones quality of life!!

Evaluation of Visual Function and Retinal Structure in Adult Amblyopes.

Evaluation of Visual Function and Retinal Structure in Adult Amblyopes.


"....Multifocal VEP amplitudes and latencies were significantly affected in amblyopic eyes and, to a lesser extent, in nonamblyopic eyes. Multifocal VEP response latencies were more delayed in anisometropic eyes than in strabismic eyes, suggesting that anisometropic and strabismic amblyopia may represent different neural abnormalities......"

Comments: Another reason why strabismus surgery may not be the first thing you recommend for those with eye turns!
