Children that are referred because they fail the eye chart …. Have a distance VA problem Pediatrician screening? School nurse screening? Only 3 states have mandatory vision screening. Only a small percentage of children ever get the care they need 25% of school children have one or more vision problems Undiagnosed untreated vision disorders are very prevalent Cost of untreated vision problems staggering All BV are treatable and preventable: Great Public Health Model

    • 3D Vision Syndrome What constitutes a syndrome?A group of symptoms that collectivelyindicate or characterize a disease,psychological disorder, or otherabnormal condition
    • So is the 3D Vision Syndrome Really a Syndrome? Yes.The symptoms and signs consistentlyinclude: headaches, nausea, dizziness, avision induced sense of motion, diplopia,blurred vision and eyestrain; as well as adisconnect between accommodation andvergence.
    • The 3D’s of 3D Viewing:Discomfort, Dizziness and Lack of Depth Discomfort: Since 3D viewing is based on the eyes converging in front of or beyond the screen, viewing 3D images can potentially create eyestrain and headaches
    • The 3D’s of 3D Viewing:Discomfort, Dizziness and Lack of DepthDizziness:3D technology canexaggerate visually inducedmotion sickness …causingconsumers to feel dizzy ornauseous during or afterviewing 3D content.
    • The 3D’s of 3D Viewing:Discomfort, Dizziness and Lack of DepthLack of Depth:A viewer lacking binocularvision, simply won‟t see 3D.While this doesn‟t pose anyproblem viewing the screen, itserves as a “vision screening”that something is abnormalwith the viewer‟s binocularvision.

    • 3D Vision Syndrome …… is comprised of a group of symptoms andphysical signs that collectively indicate orcharacterize a functional vision and/or eyehealth disorder that manifests when viewingsimulated 3D technology. These signs andsymptoms include but are not limited toheadaches, blurred vision, eyestrain, doublevision, dizziness/nausea, decreased depthperception and vision induced motion sickness.
    • So….is thisreally a publichealth issue? 70/128

Arch Ophthalmol. 2008 Oct;126(10):1336-49.Convergence Insufficiency Treatment Trial Study Group.CONCLUSIONS:Twelve weeks of OBVAT results in a significantlygreater improvement in symptoms and clinicalmeasures of near point of convergence andpositive fusional vergence and a greaterpercentage of patients reaching the predeterminedcriteria of success compared with HBPP,HBCVAT+, and OBPT. Application to ClinicalPractice Office-based vergence accommodativetherapy is an effective treatment for children withsymptomatic convergence insufficiency.

The scientific basis for and efficacy of optometric visiontherapy in nonstrabismic accommodative and vergence disorders.Optometry. 2002 Dec;73(12):735-62.BACKGROUND:For nearly 75 years, optometric vision therapy has been an important mode oftherapy for both children and adults who manifested a range of nonstrabismicaccommodative and vergence disorders.METHODS:In this article, the scientific basis for, and efficacy of, optometric vision therapyin such patients will be discussed. Using bio-engineering models of theoculomotor system as the conceptual framework, emphasis will be focused onstudies that used objective recording techniques to directly assesstherapeutically related changes in oculomotor responsivity.RESULTS AND CONCLUSIONS:The findings clearly support the validity ofoptometric vision therapy. Furthermore, theresults are consistent with the tenets of generalmotor learning.
