Detecting the serious visual disorders of childhood

 Detecting the serious visual disorders of childhood

....Vision is important throughout childhood, leading early developmental
progress, supporting academic achievement and enhancing the general
quality of life. This article is directed towards the early identification of
the serious ocular problems which may arise in children. General
screening and assessment are discussed, including important pointers
in the history and examination. Selected topics include the baby who
cannot see, refractive errors and strabismus, nystagmus, cloudy or prominent
eyes, and trauma.....

The accommodative lag of the young hyperopic patient

The accommodative lag of the young hyperopic patient

...These data from a relatively small but broad sampling of age and clinical status suggest that clinically normal young infants and children with low amounts of hyperopia have similar lags of accommodation from the first few months after birth. Subjects with greater than 4 D of hyperopia, or amblyopia or strabismus, have more variable lags and therefore evidence of abnormal visual experience....

Lazy Eye can Improve With Gaming

Lazy Eye can Improve With Gaming

....Optometry research has been looking at new ways to treat the highly common disorder of lazy eye. While eye patches were long believed to be the only, if imperfect, solution to this problem, new studies have reinforced the notion that having patients play video games could result even greater outcomes.

Amblyopia, also known as lazy eye, is a neurological disorder where the vision in one eye does not develop properly. It is a major cause of permanent visual impairment in childhood and affects nearly three percent of children, according to the National Eye Institute. It is also the most common cause of one-eye visual impairment among young and middle-aged adults. Read More.......

.....Recent research has shown that video games could also help adults affected by the condition. In a study from the School of Optometry and the Helen Willis Neuroscience Institute at the University of California, Berkley, researchers found that playing commercial video games had a noticeable impact on participants. Subjects in the lazy eye treatment pilot project experienced significant improvements in visual acuity and 3D depth perception after just 40 hours of gaming......

Comments: Amblyopia can be improved at any age. Do not let any doctor tell you different. Want more info? Go to http://www.covd.org DM

 3D in the Classroom: See Well, Learn Well
by Dominick M. Maino, OD, MEd, FAAO, FCOVD-A, Editor

It all started around 300 BC when Euclid first
observed that each eye binocular sees an image from a slightly different perspective. Italian Maestro, Leonardo da Vinci in the 1500’s then realized that having two eyes gave us a sense of depth and an ability to perceive distance. Later in the 1800’s Sir David Brewster (of the Brewster Stereoscope fame), Sir Charles Wheatstone (of the Wheatstone Stereoscope fame) and American jurist, author and inventor, Oliver Wendell Holmes (who brought 3D to the masses with his inexpensive Stereopticon) made it possible for many to experience simulated 3D images. ......

Monocular and Binocular Accommodative Flipper Rock Optometric Vision Therapy

Monocular and Binocular Accommodative Flipper Rock optometric vision therapy can be conducted in and out of the optometrist's office as a therapeutic intervention for focusing disorders. The primary focusing dysfunction this procedure treats is accommodative infacility (a problem shifting your focus from near to far and back again). Two of my students developed this video with a bit of editing assistance on my part. This video may be used by all for non-commercial purposes only. Always consult your doctor before beginning any therapy or intervention program.

THX and Optometry College Set Up One-Person 3D Theater

THX and Optometry College Set Up One-Person 3D Theater

My friend and colleague in all things 3D, Phil Lelyveld, notes that: THX has provided equipment and setup assistance to a special eye clinic just opened in Beaverton, Oregon by Pacific University’s College of Optometry.  It is the nation’s first 3D eye exam room to help people with depth perception problems, and hopes also to provide information to the 3D industry to improve the methods they use to display 3D to audiences. The clinic is already discovering what it is about viewing 3D that causes some people to have eye problems.....

Physicians and Self-Prescribing: Just Say ‘No’

Physicians and Self-Prescribing: Just Say ‘No’

....There is great uncertainty and misunderstanding in the United States regarding whether or not physicians are allowed to self-prescribe. Under federal law, physicians are not specifically prohibited from self-prescribing or prescribing for friends and family. According the Opinion 8.19 of the AMA Code of Medical Ethics, “physicians generally should not treat themselves or members of their immediate families.” The AMA cites the following reasons:....

Visual Diagnosis and Care of the Patient with Special Needs

  This is absolutely shameless self promotion....but I think this book is going to be awesome! Please realize that I am biased since I am one of the editors/authors.

This is my second book on this topic. I have also done several chapters in other books, many professional articles and blogs/website publications.

Outcome of Surgery for Esotropia in Children with Down Syndrome

Outcome of Surgery for Esotropia in Children with Down Syndrome

Twenty-one patients with a mean age at surgery of 55 months and a mean ET angle of  36Δ received surgical intervention. Of those 3 patients needed a second surgery and a second operation was recommended for 2 additional subjects.a. The mean length of follow-up was 39 months. At the last follow-up examination, fourteen patients had a deviation of 0-10Δ (thirteen esotropic and one exotropic). Five patients had a final deviation of 11-20Δ (four esotropic and one exotropic). One patient had a residual esotropia of 21-30Δ and one had greater than 30Δ of residual esotropia.

Conclusion: The motor outcomes for esotropia surgery in children with Down syndrome were not as good as those in children with acquired esotropia but were comparable to those in children with infantile esotropia. More children had residual esotropia than consecutive exotropia, which may reflect a tendency toward conservative amounts of surgery or an underlying esotropic tendency in Down syndrome. Parents of children with Down syndrome may be counseled to expect good outcomes in the surgical management of esotropia.
