Myopia and Education: There is a link!!!

...................Higher levels of school and post-school professional education are associated with a more myopic refraction. Participants with higher educational achievements more often were myopic than individuals with less education.................

Involuntary eye movement a foolproof indication for ADHD diagnosis

Involuntary eye movement a foolproof indication for ADHD diagnosis


....Attention deficit hyperactivity disorder (ADHD) is the most commonly diagnosed -- and misdiagnosed -- behavioral disorder in American children. Now a new study can provide the objective tool medical professionals need to accurately diagnose ADHD. The study indicates that involuntary eye movements accurately reflect the presence of ADHD......

Lead in preschool kids' blood tied to behavioral problems

Lead in preschool kids' blood tied to behavioral problems

Although it is well documented that lead exposure lowers children's IQ, we know little about its effect on their behavioral and emotional health. Now, a new study shows that emotional and behavioral problems are apparent even at relatively low levels of lead exposure in preschool children, and they go up in line with rising blood lead levels.
Writing in the journal JAMA Pediatrics, Dr. Jianghong Liu of the School of Nursing at the University of Pennsylvania, Philadelphia, and colleagues report how they analyzed links between blood lead levels in over 1,300 Chinese preschoolers and behavioral and emotional problems, such as showing signs of being anxious, depressed, or aggressive......

Do not disturb! How the brain filters out distractions

Do not disturb! How the brain filters out distractions

You know the feeling? You are trying to dial a phone number from memory... you have to concentrate.... then someone starts shouting out other numbers nearby. In a situation like that, your brain must ignore the distraction as best it can so as not to lose vital information from its working memory. A new paper published in Neuron by a team of neurobiologists led by Professor Andreas Nieder at the University of Tübingen gives insight into just how the brain manages this problem.
The researchers put rhesus monkeys in a similar situation. The monkeys had to remember the number of dots in an image and reproduce the knowledge a moment later. While they were taking in the information, a distraction was introduced, showing a different number of dots. And even though the monkeys were mostly able to ignore the distraction, their concentration was disturbed and their memory performance suffered......

Vision Therapy Outcomes for those with Traumatic Brain Injury

Vision Therapy Outcomes for those with Traumatic Brain Injury

Effect of oculomotor rehabilitation on vergence responsivity in mild Traumatic Brain Injury

A range of dynamic and static vergence responses were evaluated in 12 individuals with mild traumatic brain injury (age: 29 +/- 3 yr) having near vision symptoms. All measures were performed in a crossover design before and after oculomotor training (OMT) and placebo (P) training. Following OMT, peak velocity for both convergence and divergence increased significantly. Increased peak velocity was significantly correlated with increased clinically based vergence prism flipper rate. Steady-state response variability for convergence reduced significantly following OMT. The maximum amplitude of convergence, relative fusional amplitudes, and near stereoacuity improved significantly. In addition, symptoms reduced significantly, and visual attention improved markedly. None of the measures were found to change significantly following P training. The significant improvement in most aspects of vergence eye movements following OMT demonstrates considerable residual brain plasticity via oculomotor learning. The improved vergence affected positively on nearwork-related symptoms and visual attention.

Effect of oculomotor rehabilitation on accommodative responsivity in mild traumatic brain injury


Accommodative dysfunction is a common oculomotor sequelae of mild traumatic brain injury (mTBI). This study evaluated a range of dynamic (objective) and static (subjective) measures of accommodation in 12 nonstrabismic individuals with mTBI and near vision-related symptoms before and after oculomotor training (OMT) and placebo (P) training (6 wk, two sessions per week, 3 h of training each). Following OMT, the dynamics of accommodation improved markedly. Clinically, there was a significant increase in the maximum accommodative amplitude both monocularly and binocularly. In addition, the near vision symptoms reduced along with improved visual attention. None of the measures were found to change significantly following P training. These results provide evidence for a significant positive effect of the accommodatively based OMT on accommodative responsivity. Such improvement is suggestive of oculomotor learning, demonstrating considerable residual brain-visual system plasticity in the adult compromised brain.



Children with dyslexia at increased risk for physical abuse

Children with dyslexia at increased risk for physical abuse

....Adults who have dyslexia are much more likely to report they were physically abused before they turned 18 than their peers without dyslexia, according to a new study from researchers at the University of Toronto and the University of North Carolina School of Medicine in Chapel Hill.
Thirty-five per cent of adults with dyslexia report they were physically abused before they turned 18. In contrast, seven per cent of those without dyslexia reported that they had experienced childhood physical abuse.....

'Lost in translation' issues in Chinese medicine

'Lost in translation' issues in Chinese medicine

Millions of people in the West today utilize traditional Chinese medicine, including acupuncture, herbs, massage and nutritional therapies. Yet only a few U.S. schools that teach Chinese medicine require Chinese-language training and only a handful of Chinese medical texts have so far been translated into English.
Given the complexity of the language and concepts in these texts, there is a need for accurate, high-quality translations, say researchers at UCLA's Center for East-West Medicine. To that end, the center has published a document that includes a detailed discussion of the issues involved in Chinese medical translation, which is designed to help students, educators, practitioners, researchers, publishers and translators evaluate and digest Chinese medical texts with greater sensitivity and comprehension.
"This publication aims to raise awareness among the many stakeholders involved with the translation of Chinese medicine," said principal investigator and study author Dr. Ka-Kit Hui, founder and director of the UCLA center.......

Randomized pediatric autism clinical trial conducted entirely online

Randomized pediatric autism clinical trial conducted entirely online

....UC San Francisco researchers have completed the first Internet-based clinical trial for children with autism, establishing it as a viable and cost effective method of conducting high-quality and rapid clinical trials in this population.
In their study, published in a recent issue of the Journal of the American Academy of Child and Adolescent Psychiatry, the researchers looked at whether an Internet-based trial was a feasible way to evaluate whether omega-3 fatty acids helped reduce hyperactivity in children with autism. The authors found that not only was it a valuable platform for conducting the randomized clinical trial, but that it was both cost and time effective, as well....

The Treatment of Amblyopia in Adults

The Treatment of Amblyopia in Adults

I was recently quoted in the Dr. Patch blog. 

....Can amblyopia still be treated in adults? It’s a question thousands would like answered and you can find countless articles all taking different stands and confusing us more and more on the matter.
The question remains: can adults suffering from their amblyopic eye benefit from an effective treatment or is this just wishful thinking?
Please note that the Dr. Patch website is dedicated to selling eye patches and other occlusion devices for children and adults. They have a wide variety of occlusive devices available, so most will be able to find something that works for their child/patient.
In addition they do a pretty good job at providing information about amblyopia, strabismus and other similar problems. I would like to see more information about vision therapy and how this treatment option emphasizes the binocular vision aspect of treating amblyopia as a binocular vision problem and not just a problem of visual acuity.
Please note I have no financial interest in this blog or the products it sells.
