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

Randomized clinical trial of treatments for symptomatic convergenceinsufficiency in children. 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.

Ciuffreda KJ. 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.
