Best Careers 2009: Optometrist

...Optometrist. Ophthalmologist. Optician. Many people confuse them, but a career as an optometrist offers unmistakable advantages. Optometrists on average earn more than twice as much as opticians .... And optometrists get to do most of what ophthalmologists do, ... diagnose and treat eye diseases, perform minor surgery (in some states), and of course fit people for glasses and contact lenses. Yet the required training is years shorter than it is for an ophthalmologist: a four-year, post-bachelor's program.....

...Smart Specialty...Pediatric optometry. The eye problems of children are generally among the most remediable. And the American Optometric Association projects high growth in this niche....

11 Easy Ways to Load Up on Healthy Omega-3 Fats

...Omega-3 fatty acids are essential to good health, but their benefits may be missed because the American diet is chock full of omega-6 fatty acids instead. (Learn more about the pros and cons of omega-3s and 6s here.) Many foods contain both fatty acids. To ensure you get your fill of -3, you'll need to be conscientious at the grocery store. Here are 11 ways to get more omega-3 and crowd out omega-6:...

Motion Illusions Reveal New Insights Into Perception

...In the classic waterfall illusion, if you stare at the downward motion of a waterfall for some period of time, stationary objects - like rocks - appear to drift upward. MIT neuroscientists have found that this phenomenon, called motion aftereffect, occurs not only in our visual perception but also in our tactile perception, and that these senses actually influence one another. Put another way, how you feel the world can actually change how you see it - and vice versa...

Preterm Infants At Risk Of Eye Disease Can Now Be Identified By Their Weight Gain

... simple way of establishing which preterm infants are at risk of developing the eye disease ROP is to follow their weight gain. A new study from the Sahlgrenska Academy, University of Gothenburg, Sweden, suggests that following weekly weight development might replace the need for considerably more expensive ophthalmological examinations...

Lens Thickness Changes Among Schoolchildren in Taiwan

Long-term application of computer-based pleoptics in home therapy: selected results of a prospective multicenter study.

The visual acuity was increased about two logarithmic steps by an occlusion combined with computer training in addition to the earlier obtained gain of the same amount by occlusion alone. Recalculated relatively to the duration of the therapy periods, the computer training combined with occlusion was found to be about twice as effective as the preceding occlusion alone.

ADHD as a (non) allergic hypersensitivity disorder: A hypothesis

Comments: I edit a journal (Optometry & Vision Development) so I know the pressures many journal editors face...but what is right, ethical and moral will never change. It is just wrong to do what these indviduals may have done. Medicine and the research it conducts, really received a "black eye" because of this...DM

First Large Study Of Preschool Children's Vision Finds Need For Improved Care

...The study found that 5.1 percent of participating children had refractive errors that would benefit from prescription eyeglasses, based on current correction standards for this age range. ...Farsightedness was the most common refractive error among both African-Americans (4.4 percent) and white children (8.9 percent); these rates did not change significantly as the children aged....

Comments: Can we finally stop the debate as to whether or not children need comprehensive eye examinations? They do. All should have comprehensive eye and vision examinations at least before they enter school, and then yearly... or minimally at these intervals :3rd grade, 5th grade and before they enter High School. No ifs, no buts, no maybes....they need to be seen by a pediatric optometrist! DM

Scientists Propose New Theory Of Autism

Poor nutrition in the womb causes permanent genetic changes in the offspring

..The new science of epigenetics explains how genes can be modified by the environment, and a prime result of epigenetic inquiry has just been published online in The FASEB Journal (http://www.fasebj.org): You are what your mother did not eat during pregnancy. In the research report, scientists from the University of Utah show that rat fetuses receiving poor nutrition in the womb become genetically primed to be born into an environment lacking proper nutrition. As a result of this genetic adaptation, the rats were likely to grow to smaller sizes than their normal counterparts. At the same time, they were also at higher risk for a host of health problems throughout their lives, such as diabetes, growth retardation, cardiovascular disease, obesity, and neurodevelopmental delays, among others. Although the study involved rats, the genes and cellular mechanisms involved are the same as those in humans....

ECG Before Starting Stimulants for ADHD Called a Cost-Effective Screen

...A screening ECG before starting stimulant medications for kids with attention deficit hyperactivity disorder (ADHD) may be a cost-effective way of picking up unrecognized cardiac problems, researchers said.

Comments: So let me get this straight....it's cost effective to have all these kids get an ECG....but it is not cost effective for all children to have comprehenisve eye examinations? What am I missing here? DM

Do visual impairments affect risk of motor problems in preterm and term low birth weight adolescents?

...Visual impairments influence motor problems in VLBW adolescents, whereas motor problems in small for gestational age adolescents seem to be unaffected by visual impairments.

Assessment of cerebral visual impairment with the L94 visual perceptual battery: clinical value and correlation with MRI findings

ABSTRACT

In this article we describe visual perceptual abilities of a clinical population, referred for visual problems to our multidisciplinary team and assessed with the five computer tasks from the L94 visual perceptual battery. Clinical and neuroimaging findings were correlated with the findings on this task battery. Seventy children (35 males, 35 females) constituted our cohort. Age ranged from 4 to 20 years (mean 7y [SD 3y]). Forty children were born before 37 weeks gestational age. Thirty-six children had cerebral palsy (CP), of whom 24 had spastic diplegia, five had spastic hemiplegia, and four had spastic quadriplegia. Three children had ataxic CP. Perceptual visual impairment (PVI) was established in comparison to the performance age obtained on non-verbal intelligence subtests, instead of chronological age. Our results suggest that children with a history of preterm birth and a clinical CP picture are most at risk for a specific PVI. Correlations among other clinical variables did not define a clinical subgroup more at risk. Children with periventricular leucomalacia were almost equally represented in both PVI and non-PVI groups. Normal magnetic resonance imaging did not exclude the presence of PVI. In these children, however, we found another impairment profile, more in favour of dorsal stream impairment.

Long-term visual outcomes of laser-treated threshold retinopathy of prematurity: a study of refractive status at 7 years

...The majority of patients with diode laser-treated threshold ROP had favourable anatomical and visual outcomes. However, anisometropia, advanced refractive error, strabismus, and perinatal neurological events remain important causes of impaired visual function. Long-term follow-up is very important for early detection and timely treatment of these ocular morbidities....
