Epigenetics

... the term epigenetics refers to changes in phenotype (appearance) or gene expression caused by mechanisms other than changes in the underlying DNA sequence, hence the name epi- (Greek: επί- over, above) -genetics. These changes may remain through cell divisions for the remainder of the cell's life and may also last for multiple generations. However, there is no change in the underlying DNA sequence of the organism;[1] instead, non-genetic factors cause the organism's genes to behave (or "express themselves") differently.........

Comments: Have functional optometrists been practicing "epigenetics" since the 1930's by altering the environment so that gene expression changed resulting in a better functioning visual system? DM

Infl ammation in Alzheimer’s disease: relevance to pathogenesis and therapy

Evidence for the involvement of inflammatory
processes in the pathogenesis of Alzheimer’s disease (AD) has been documented for a long time. However, the infl ammation hypothesis in relation to AD pathology has emerged relatively recently. Even in this hypothesis, the inflammatory reaction is still considered to be a downstream eff ect of the accumulated proteins (amyloid beta (Aβ) and tau). This review aims to highlight the importance of the immune processes
involved in AD pathogenesis based on the outcomes of the two major inflammation-relevant treatment strategies against AD developed and tested to date in animal studies and human clinical trials - the use of anti-inflammatory drugs and immunisation against Aβ.

Scientists identify one genetic cause of long-sightedness.

From AOA First Look:

Australia's Sydney Morning Herald /AAP (2/3, Rose) reports that Australian scientists "have identified one of the genetic causes of long-sightedness, a breakthrough that could lead to the development of a drug to treat vision loss." Researchers "identified changes in the hepatocyte growth factor (HGF) gene which...are now suspected of playing a disruptive role in the proper development of the eye."

Elevated Brain Levels Of Magnesium Enhance Learning And Memory

...New research finds that an increase in brain magnesium improves learning and memory in young and old rats. The study, ...suggests that increasing magnesium intake may be a valid strategy to enhance cognitive abilities and supports speculation that inadequate levels of magnesium impair cognitive function, leading to faster deterioration of memory in aging humans. ...

Wakeful Resting Linked To Improved Memory

New research from the US shows that resting while awake appears to strengthen memory, revealing new insights into how forms of rest other than sleep, affect the memory consolidation process. The findings suggest that even though it may not look like it, when we rest while awake, our brains are still working, something we may find hard to accept in an information technological world that is on the go 24/7.........

Comments: Well, now I can tell Dr. Kent Daum, my Dean at the Illinois College of Optometry, that not only am I doing work while drinking coffee...but also when I'm resting in a wakeful state! DM

Laser-assisted subepithelial keratectomy and Amblyopia

...The mean spherical equivalent (SE) in all 72 hyperopic eyes (47 patients) was +3.42 diopters (D) (range 0.00 to +12.50 D) preoperatively and +0.59 D (range −1.25 to +2.00 D) 1 year postoperatively. After LASIK, 41.7% of eyes had improved corrected distance visual acuity (CDVA). No patient had reduced CDVA or loss of fusional ability; there was a 25.0% improvement in stereopsis at 1 year. The mean anisometropic difference in the hyperopic anisometropic amblyopia subgroup (18 eyes, 10 patients) was 4.39 D (range +1.75 to +7.75 D) preoperatively and +0.51 D (range 0 to +0.875 D) at 1 year. One year postoperatively, 83% of anisometropic eyes were within ±1.00 D of the fellow eye and 94.0% were within ±3.00 D. Postoperatively, 64.7% of eyes had improved CDVA with no reduced CDVA or loss of fusional ability; there was a 22% improvement in stereopsis at 1 year....

Comments: If I am reading these results correctly then...59% did not have improved CDVA, 75% had no improvement in stereopsis and after 1 yr 36% did not have improved visual acuity and 78% did not have an improvement in stereopsis! So you subjected these children to surgery....in which you really have no idea what will happen to their eyes 20 to 60 years down the road...for not a whole lot of improvement! Ok so tell me about the risk vs benefit ratio when standard amblyopia therapy gives just as good or better results without the potential risk? DM

When Your Child Doesn't Want to Read There May Be an Underlying Vision Problem

...Our optometrist told us that many children are misdiagnosed with Dyslexia, Attention Deficit Disorder (ADD), or Attention Deficit Hyperactivity Disorder (ADHD) when it is really a vision problem that is impairing the signal between the eyes and the brain. In the end, vision therapy wasn't the only solution to my son's vision problem. He now wears bifocal glasses to help his eyes focus and work together. He has never complained about wearing glasses. In fact, when we drove away from the doctor's office, he exclaimed, "Look, there's a stop sign!" when we were still a half a block away. I said, "Didn't you see that before?" He said, "I couldn't see it clearly until I got close to it."...

3-D Avatar sickness a public health concern...signs of an underlying vision problem.

Friend and colleague, Dr. Dan Fortenbacher notes that:.....Thanks to Avatar, binocular vision problems that cause stereo blindness are now gaining more public awareness. Yes, the stereo blind individual not only "can't see it" (3-D), but for 165 minutes of this movie they will have a "blurry" or "smeary" visual experience. Thus, for the stereo blind, Avatar is just not enjoyable because it just looks out of focus.

However, for those who have another common binocular vision problem, Convergence Insufficiency (CI), Avatar may make them sick! Yes, Avatar can actually be a "health hazard" for those with weak binocular vision ability. ...

Avatar, 3D Movies, and Our Sense of Identity.

Since I was cross-eyed and stereoblind until I underwent optometric vision therapy at age 48, my friends keep asking me this question. Yes, I saw Avatar, and I saw all the 3D. What I particularly liked was the way the forest appeared to recede far into the distance and the way the seeds of the Tree of Life floated forward in the space between me and the movie screen. Those seeds reminded me of the lovely comb jellies or "sea walnuts" that inhabit the waters around Woods Hole, MA in late summer. Sea walnuts are bioluminescent so at night while swimming you can see them floating at different distances in the dark waters around you....

Comments: My friend and colleague, Susan Barry, PhD, writes a blog for Psychology Today telling of her experiences in 3D (Stereo Sue). She attained 3D vision as an adult and marvels at this wonderful way to view the world every day. Check out what she has to say about Avatar and 3D vision. DM

Controversial eye surgery put on hold

Comments: One of the main problems with LASIK for children is that they will be living into their 90's or longer. As we age our eyes change...which includes the thinning of the cornea....so if you burn off corneal tissue when the patient is a child...what will happen to them when they are in their 90's? We do not know. Be careful. LASIK should not routinely be used for children....DM

Consumer Reports Health Blog:Having trouble seeing 3D?


If you weren’t blown away by the three-dimensional effects in James Cameron’s movie "Avatar" or you left the theater with eyestrain or a headache, your eyes might not be 3D-ready. Around 5 to 10 percent of people don’t have true depth perception, and far more may have trouble with their binocular vision, which is needed to see the 3D images in movies or the new 3D TVs on the horizon.....Also consider asking about a referral to a developmental optometrist, a practitioner specially trained to help patients improve their visual performance, which can help with tasks such as seeing 3D.

Kiplinger Magazine: 13 Careers for the Next Decade

Comment: Optometry is one of the best careers!!

....In these roiling times, what are smart career choices? Of course, the best career for one person can be the worst for another, but I believe these 13 are particularly worthy of attention. From among thousands of occupations, I selected the 13 that rank best overall based on these criteria:

• Likelihood of sustaining at least a middle-class income. This subsumes three factors: likely job growth, income potential and being under the radar (so there's less competition for jobs).

•Socially redeeming. There may be jobs, for example, as casino managers and tobacco executives, but such occupations were immediately excluded from consideration.

•Quality of life. Reasonable work hours, freedom from toxic or noisy work environments, and so on.

•Status. Most Kiplinger readers will not, for example, be attracted to owning gas stations, even though some gas-station owners make a great deal of money.....

Lancet: Time to look beyond MMR in autism research

...Is the measles, mumps, and rubella (MMR) vaccine safe? Yes, acceptably so, is the only conclusion possible to reach in the face of the totality of the epidemiological evidence. There are no substantiated data to suggest that the MMR vaccine causes autism, enterocolitis, or the syndrome first described by Andrew Wakefield and his colleagues in The Lancet in 1998. New research from some of the same authors as the 1998 Lancet report, in conjunction with a Dublin group led by Prof John O'Leary, has been published early online in Molecular Pathology. Fragments of the measles virus genome are reported in 75 of 91 children with ileal-lymphoid-nodular hyperplasia, enterocolitis, and developmental disorder, compared with five of 70 control children. But, crucially, these data do not support any link to the MMR vaccine, since no vaccine-specific strain data are presented for measles, mumps, or rubella. This latest twist has prompted Prof John Walker-Smith to end his silence since the publication of the first 1998 paper, of which he was the senior author.

Brain's Wiring Makes Change Hard

...By the end of January, many New Year's resolutions have been tossed out with the leftover holiday cookies. That's because change is hard -- and neuroscientists are learning why.

Advances in neuroimaging have enabled researchers to peer inside the brains of addicts and patients with addictive behaviors. They can see in real-time what gets patients hooked: how the brain's reward system -- based largely on the neurotransmitter dopamine -- thirsts for more, while inhibitory control centers experience a system failure....

No Link Found Between Autism And Celiac Disease

...Researchers compared blood samples of 34 children with autism to samples of 34 children without autism who had been referred to an outpatient clinic of the same hospital. They looked for two antibodies used to help detect celiac disease--anti-gliadin antibodies and anti-endomysial antibodies. Biopsies of the small intestine were offered to children who tested positive for either antibody to confirm the diagnosis. Each group contained 18 boys and 16 girls between the ages of four and 16.

The study found autistic children were no more likely than children without autism to develop celiac disease. ...

Combined Approach May Be Better Way to Treat Autism

...For years, the behavioral and developmental camps have argued over which theory is more effective in teaching communication and other skills to preschool-aged children with autism.

But while the theories differ, the actual methods the two camps ultimately use to teach children can be strikingly similar, especially when the treatment is naturalistic, or unstructured...

...What moves you to demand better of Illinois? Perhaps the deaths of those nine innocents, six of them Willis children, caused by truckers who paid bribes for their Illinois licenses?

How about your lawmakers' foolish spending and borrowing, and the massive debts that you and your grandchildren now have to retire — does that move you? How about tax policy that drives jobs elsewhere, and government insolvency so severe that employers won't want to be here to pay off all the obligations — does that move you? How about the legislators whose votes long enabled then- Gov. Rod Blagojevich? The foisting on you of Sen. Roland Burris? The refusal of incumbent pols to let you recall them, or to let you vote on Barack Obama's successor in the U.S. Senate?...
