What is an Optometrist?

Optometrist: A health care professional who is licensed to provide primary and specialized eye and vision care services:

An optometrist is a Doctor of Optometry, an O.D. (Doctors of Medicine, or MDs are NOT Optometrists.). To become an optometrist, one must complete pre-professional undergraduate college education followed by 4 years of professional education in a college of optometry. Many optometrists also do a residency.

Flu vaccines for all kids, federal panel advises

5 ways medical physics has changed health care

Many of the greatest inventions in modern medicine were developed by physicists who imported technologies such as X rays, nuclear magnetic resonance, ultrasound, particle accelerators and radioisotope tagging and detection techniques into the medical domain. There they became magnetic resonance imaging (MRI), computerized tomography (CT) scanning, nuclear medicine, positron emission tomography (PET) scanning, and various radiotherapy treatment methods. These contributions have revolutionized medical techniques for imaging the human body and treating disease.

photorefractive keratectomy and laser-assisted subepithelial keratectomy in children

Photorefractive keratectomy and LASEK were effective and stable surgical alternative treatments in children with refractive errors who were unable to tolerate or who failed conventional methods of treatment.

Comment: PRK and LASEK were done under general anesthesia. There is always risk involved when you place children as young as 12 months of age under general anesthesia. Also note that PRK and LASEK significantly affects the thickness of the cornea. As we age, the cornea thins. Since these children will probably have an opportunity to live well into their 70's and 80's, what will happen to these corneas over time? This procedure is NOT for most children...but may be appropriate in limitted cases. DM

Herbal Supplement May Protect Memory After Age 85

Among 118 people 85 or older, those who took the supplement (ginkgo extract ) reliably had a 70% lower risk of developing mild memory problems than those who took a placebo, Hiroko Dodge, Ph.D., of Oregon State University here, and colleagues reported online in Neurology.

Comment: I'm not 85 yet....but will need all the help I can get when I get there! (Actually, my wife says I could use some help in the memory department right now! DM

Google to launch electronic health records project.

Both the Wall Street Journal and Government Health IT have stories about how Google, Microsoft and others will host your personal medical records to share with whomever you think appropriate. Unfortunately, these business' are not held to the HIPPA standards that we are expected to uphold....would advertisers market allergy products to you if they found out you have allergies? Could cause many privacy problems.

Autism's origins: Mother's antibody production may affect fetal brain

The mothers of some autistic children may have made antibodies against their fetuses’ brain tissue during pregnancy that crossed the placenta and caused changes that led to autism, suggests research led by Johns Hopkins Children’s Center investigators and published in the February issue of the Journal of Neuroimmunology.

The causes of autism, a disorder manifesting itself with a range of brain problems and marked by impaired social interactions, communication disorders and repetitive behaviors, remain unknown for an estimated 90 percent of children diagnosed with it. Genetic, metabolic and environmental factors have been implicated in various studies of autism, a disorder affecting 1 in 150 U.S. children, according to estimates by the Centers for Disease Control and Prevention.

Comment: Autism's etiology continues to be a mystery. Click on the title to read the full story. DM

TV Could Be Disrupting Your Kid's Sleep

It may seem like a good idea: Use a bit of TV viewing to help your young child get to sleep.
But a growing body of research is finding that infants and children under the age of 3 who watch TV -- even too much TV during the day -- struggle with interrupted sleep and irregular bed and naptime schedules.

LASIK failure toll can be high

Comment: Besides the problems noted in this story, I've also seen patients develope binocular vision problems (strabismus, convergence excess, etc) as well. Please recommend that all LASIK patients have a comprehensive binocular vision assessment before surgery. DM

FDA to study effects of complications from eye surgery; some blame them for depression, suicide

Patients who undergo vision-correcting laser eye surgery sign a release form with an extensive list of risks, but some researchers and former patients say a potential complication is not mentioned: depression that can lead to suicide...."Frustration and sorrow can follow any unsuccessful surgery, but when the procedure leaves a patient with unremitting eye pain or permanently impaired vision, the emotional toll can be severe."

Retinopathy of Prematurity

Fleck BW et al. - Retinopathy of Prematurity (ROP) occurs when premature birth interrupts normal retinal vascular development. Postnatal tissue oxygen levels are significantly higher than those present in utero. Oxygen therapy further increases oxygen levels in the developing retina.

Prematurity and Amblyopia

O'Connor A et al. - There are numerous reports of an increase in refractive errors and amblyogenic factors in the low birth weight population relative to children born at full term. One key aspect of a screening programme is the age at testing as this dictates the possible tests used which impacts on the efficacy. However, although the prevalence of strabismus and refractive errors is well documented the development of these conditions is poorly understood so for this and other reasons it is difficult to devise the most effective screening programme.

Ametropia, Preschoolers' Cognitive Abilities, and Effects of Spectacle Correction

Comment: Have your young child's eye examined immediately. Wearing glasses improves visual motor function! DM

Ametropia, Preschoolers' Cognitive Abilities, and Effects of Spectacle Correction . nne-Catherine Roch-Levecq, PhD; Barbara L. Brody, MPH; Ronald G. Thomas, PhD; Stuart I. Brown, MD Arch Ophthalmol. 2008;126(2):252-258.

Objectives To examine cognitive abilities of low-income preschoolers with uncorrected ametropia and effects of spectacle correction.
Methods Baseline and 6-week data from a longitudinal controlled study were analyzed. Subjects were 70 preschoolers (mean age, 4.6 years; 60.0% were female; and 85.7% were Latino), including 35 children with previously uncorrected ametropia and 35 emmetropic control subjects. Ametropia was defined as bilateral hyperopia of 4.00 diopters (D) or more in children aged 3 to 5 years, astigmatism of 2.00 D or more in children aged 3 years and 1.50 D or more in children aged 4 and 5 years, or a combination of both. Emmetropia was defined as 2.00 sphere diopters or less and 1.00 cylinder diopter or less in both eyes. Ametropes were assessed before and 6 weeks after correction and compared with control subjects. Primary and secondary outcome measures were Beery-Buktenica Developmental Test of Visual-Motor Integration and Wechsler Preschool and Primary Scale of Intelligence–Revised scores, respectively.
Results At baseline, uncorrected ametropes scored significantly lower on the Beery-Buktenica Developmental Test of Visual-Motor Integration (P = .005) and the Wechsler Preschool and Primary Scale of Intelligence–Revised performance scale (P = .01). After 6 weeks of correction, the ametropic group significantly improved on the Beery-Buktenica Developmental Test of Visual-Motor Integration compared with emmetropic control subjects (P = .02).

Conclusions Preschoolers with uncorrected ametropia had significant reduction in visual-motor function. Wearing spectacles for 6 weeks improved Beery-Buktenica Developmental Test of Visual-Motor Integration scores to emmetropic levels.

Government Concedes Vaccine-Autism Case in Federal Court - Now What?

After years of insisting there is no evidence to link vaccines with the onset of autism spectrum disorder (ASD), the US government has quietly conceded a vaccine-autism case in the Court of Federal Claims.


Comment: I'm not convinced just yet. You can settle a legal case for many reasons. No research that I know of indicates mercury as a cause of autism. DM

Binocular photophobia after surgical treatment

Lew H, Kim CH, Yun YS, Han SH. Binocular photophobia after surgical treatment in intermittent exotropia. Optom Vis Sci. 2007 Dec;84(12):1101-3.

PURPOSE: This study examined the rate of binocular photophobia in intermittent exotropia patients before surgical correction, and the factors affecting this rate. The study also investigated the factors affecting postsurgical disappearance of binocular photophobia.

METHODS: The study involved 162 basic type intermittent exotropia patients who underwent surgical correction between March 2001 and January 2006. The study did not include patients with entropion, congenital cataract, or retinal abnormalities. Parents of the patients were questioned to determine which patients had monocular eye closure in bright light and which had disappeared after bilateral lateral rectus recession. Data was analyzed to determine the factors affecting monocular eye closure before surgery and disappearance after surgery.

RESULTS: Of 162 patients, 96 patients had binocular photophobia (60.2%). Photophobia was found to be associated with an angle of exodeviation at distance >25 Prism Diopter (Delta) (p 3D 0.02), and stereoacuity worse than 60 s (p 3D 0.02). We defined satisfactory surgical outcome as a deviation of <10>.

Comment: Surgical intervention can have unwanted side effects. Please ask your ophthalmic surgeon about these unwanted side effects before having any surgery. DM

Patching for Amblyopia

Objectively monitored patching regimens for treatment of amblyopia: randomised trial

Participants: 97 children with a confirmed diagnosis of amblyopia associated with strabismus, anisometropia, or both.

Conclusions Substantial (six hours a day) and maximal (12 hours a day) prescribed occlusion results in similar visual outcome. On average, the occlusion dose received in the maximal group was only 50% more than in the substantial group and in both groups was much less than that prescribed. Younger children required the least occlusion.

Comment: Recent studies suggest that as little as 2 hours of patching a day with active therapy is also very effective. DM

Computer Vision Syndrome

Though it will probably never lead to a world-wide ban of computers, an estimated 40 percent to 70 percent of computer users suffer from dry, irritated eyes associated with Computer Vision Syndrome. The good news is that it can be treated.

Older Children More Likely to Develop Vision Disorders

In a study of more than 6,000 Los Angeles-area children – the largest study of its kind – researchers at the Keck School of Medicine of the University of Southern California (USC) found that both strabismus (commonly known as cross-eyed or wall-eyed) and amblyopia (often referred to as lazy eye) were more prevalent in older children than in younger children.

Vision is Critical for Child Development

...When it comes to early childhood development, vision is critical. Experts estimate the 80 to 90 per cent of early learning takes place through vision, placing visually impaired youngsters at risk of experiencing significant developmental delays.

That’s because a person’s visual system involves much more than the eyes; it interacts with the body’s muscles to develop reaching, crawling, grabbing and walking skills in infants and children. In fact, two–thirds of the functions of the brain are associated with vision....

Maximizing BrainWare Safari

Maximizing Your BrainWare Experience

by Dominick Maino, OD, MEd, FAAO, FCOVD-A

In order to maximize the effects of BrainWare Safari software, you may need to ensure that your child’s visual system is working correctly. The areas that should be assessed by your pediatric optometrist include: Visual Acuity, Refractive Error, Binocularity and Eye Health. (Originally published in BrainWare Bulletin May 2007)

Visual Acuity
The measurement of Visual Acuity is used to determine how clear your vision is at all distances. If you are farsighted, nearsighted or have astigmatism1, your eye sight may not be clear enough to allow you to maximize the learning effects of BrainWare Safari. Your vision will not only be “fuzzy” but can also lead to visual discomfort, fatigue, and headaches, as well as an avoidance of many near tasks such as reading or using a computer.

Refractive Error
Refractive Error is the amount of myopia (nearsightedness), hyperopia (farsightedness) and astigmatism you may have. All three of these vision disorders can affect how well and comfortably you see. All three can be easily corrected by using appropriately prescribed eye glasses.

Binocularity
An assessment of Binocularity or eye teaming often includes an evaluation of the quality of eye movements (saccades2 and visual tracking/pursuits), eye coordination (convergence/divergence), focusing (the ability to maintain clear vision at near), depth perception (3D vision) and many other functional vision areas. If any of these visual skills are poor, you can experience double vision, headaches, blur at near and many other symptoms that would make using a computer difficult. Your optometrist may recommend special glasses, optometric vision therapy or other treatment options to correct many of these problems.

Eye Health
Although eye health problems in children are usually rare, the more frequently seen problems include “pink eye” (conjunctivitis) and ocular allergies. Conjunctivitis can be caused by viruses, bacteria and allergies. Allergies, for instance, typically result in itchy, watery eyes that make concentrating on any activity very difficult. Your pediatric optometrist can diagnosis and treat these problems so that your child can see clearly and comfortably.

School Vision Screenings
School Vision Screenings frequently miss many of the potential problems noted above. Only a comprehensive eye and vision examination will make sure your child is ready for everything
BrainWare Safari has to offer.

If you want to maximize the benefits of BrainWare Safari, you should make sure your children’s eyes see clearly, work together appropriately and are healthy. For additional information on this topic, use your Internet connection to go to the following websites:
