Virtual 3D technologies have reached a tipping point in recent years. 3D is now being used in various areas including movies, television, video games, education, and medical imaging. While 3D provides an immersive experience, prolonged 3D viewing can cause vision problems collectively known as 3D vision syndrome. The symptoms of 3D vision syndrome include headaches, eyestrain, blurred vision, and double vision. It is diagnosed through a comprehensive eye exam and binocular vision testing. Treatment involves prescribing glasses, vision therapy exercises to improve binocular function, and taking breaks when viewing 3D content. A case study describes one patient's experience with 3D vision syndrome and successful treatment through optometric vision therapy.
3D Vision Syndrome:A Technologically Induced Visual ImpairmentDominick Maino
3D Vision Syndrome is a public health imperative that if left undiagnosed and untreated will result in millions of individuals world wide who cannot benefit or enjoy 3D content. Individuals experience many symptoms including but not limited to headaches, blurred vision, double vision, asthenopia, eyestrain, and vision induced motion sickness. This disorder can be diagnosed and then treated with glasses, prisms, and optometric vision therapy. Once treated most individuals can then enjoy and benefit from viewing 3D content.

My students and I wrote several translations of how to conduct an eye examination (mostly my students since my language skills are not very good!). I know there are many ways, and perhaps better ways to ask these questions, but this could be a starting point. Feel free to adapt this to your needs and to make this even better. Please share when you do.

Neuroplasticity and Vision Therapy for Adults; A Case SeriesDominick Maino
This poster was presented at the American Optometric Association's Annual meeting in Boston, MA 06/2016
The bottom line:
The visual cortex has the capacity for experience dependent change (neuroplasticity) throughout life. Unfortunately, when it comes to the adult with binocular vision problems, this is not always recognized as being true even though there is strong clinical evidence to suggest a high level of adult neuroplasticity. Current research shows that adults tend to have numerous anomalies associated with the binocular vision system especially within certain populations. This case series demonstrates how those even approaching 70 years of age can benefit from optometric vision therapy.

Writing the Perfect Poster Abstract in 20 Minutes or LessDominick Maino
One of the easiest ways to begin your publishing career is to present a poster during one of the many annual meetings held by professional optometry. These meetings include but are not limited to the College of Optometrists in Vision Development, American Academy of Optometry and the American Optometric Association. This presentation reviews the step by step process involved in writing an abstract that will be accepted for presentation by these and other organizations most of the time. Once the abstract is written, you are one third of the way to making a significant contribution to the optometric literature. The other two thirds include, creating the poster and writing the final paper to be submitted to an appropriate journal for publication (the last two topics will be addressed at other meetings and/or within future VDR articles). You are encouraged to bring information for a case report and/or case series that you wish to use for a poster in the future.
This course presents the latest information concerning cortical visual impairment, its etiology, diagnosis and treatment. Various topics reviewed include cortical vs cerebral visual impairment, ventral/dorsal visual streams, visual acuity, and contrast sensitivity. Also discussed are various retinoscopy techniques, overlapping functional vision disorders, and visual stimulation/therapy for these disorders.
Course Objectives
At the end of this course, the participant will:
Be able to identify cortical vs cerebral visual impairment
Be able to access various vision functions such as visual acuity, contrast sensitivity, oculomotor and accommodative disorders
Be able to treat the diagnosed vision problems with all the tools available to the optometrist (spectacles, low vision devices, vision rehabilitative techniques)
Be aware of and use outside resources to supplement and add to any therapeutic interventions recommended

Conclusion
It is time for all to put aside our agendas,
our biases, our preconceived notions. It is time
to work together to determine best practices
even if it is contrary to prevailing opinion. The
world is not flat. Amblyopia can be treated at
any age. And optometric vision therapy is an
appropriate treatment modality for disorders of
he binocular vision system.

Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.
