  • Let’s Get Down to STRABusiness

    • Get your growth mindset in gear as we start with the fundamentals of ABC (learning a safe approach when working with patients with anomalous binocular correspondence), learn the ups and downs of treating with patients with vertical challenges and the ins and outs of patients with exotropia and esotropia. A fun and dynamic workshop geared toward active vision therapist/doctor/patient care TEAM members learning through patient stories, hands-on discovery and interaction. The goal is to help end the senseless struggle and misinformation about the joys and challenges of people with strabismus.

  • Learn: • The historical shift of care from anomalous retinal correspondence, to

    anomalous correspondence to anomalous binocular correspondence, (ABC)

    • A safe vision therapy approach for strabismus and ABC, to avoid diplopia

    • The value and art of emphasis on peripheral fusion lock before central fusion to gain stereovision

    • What difference stereovision can make in daily life

    • What opportunities may be blocked without vision therapy

    • Core vision therapy procedures to use gain peripheral fusion and stereovision

    • To collaborate regarding ABC with your colleagues , OMD and other professionals

    • About resources available regarding ABC

  • Introduction

  • Start With Why!

  • DISCLAIMER – VISION ISN’T EVERYTHING…

    VISION IS A PIECE OF THE PUZZLE

  • VISION GUIDES US • Seeing

    • Processing

    • Directing action in response to visual information, other senses and past experience

    • Eyes, brain and body working together

    • Directing movement

    • A learned process

    • Rehabilitation - neuroplasticity

  • VISION IS LEARNED VISION CAN BE RE-LEARNED VISION CAN BE ENHANCED

    VISUALLY READY TO LEARN? VISUALLY READY TO WORK? VISUALLY READY TO PLAY? VISUAL SKILLS CAN BE DEVELOPED

  • •How is vision impacting what you NEED to do?

    •How is vision impacting what you WANT to do?

    •How is vision impacting HOW WELL you want to do it?

  • WHAT IS STRABISMUS?

    Two eyes don’t align Called strabismus or tropia

    Test: unilateral cover test

    Eso, exo, vertical, hyper, hypo, com, non- comitant,

  • Cover Test

    •Direction of misalignment: • Inward: convergent strabismus or esotropia

    • accommodative esotropia

    • Outward: divergent strabismus or exotropia • Vertical: vertical strabismus, hyper or hypotropia

    •Which eye turns: • Right eye (OD) • Left eye (OS) • If goes back and forth between eyes: alternating • One eye more than another OD >OS, OS > OD

  • •At what distance is the misalignment: •Distance •Near

    •Is the angle the same in all 9 areas of gaze •Yes: comitant •No: non-comitant

    • III Nerve, • IV Nerve • VI Nerve • Brown’s Syndrome

    •Amount of time: •Constant •Once in a while: intermittent

  • Alternating Cover Test

    •Amount of deviation

    •Measured in prism diopters

  • Language is important:

    I am a person with strabismus vs. I am a strabismic

    Patient has strabismus vs. Patient is strabismic

    Patient is a person vs. Patient is a diagnosis

  • Goals in Vision Therapy Patient vs. Doctor Goals

    • Being less clumsy

    • More comfortable with night driving

    • Eyes more cosmetically aligned

    • Not just about stereopsis

    • Stereopsis may be a bonus

    Versus:

    • Better optometric findings and stereopsis

  • Start With Why

    Patients with Vertical Strabismus Challenges

  • •What problems can a vertical imbalance create or compound for a person’s body?

    •What impact can vertical imbalance have on being anxious, fearful or fearless?

    • That problems can a vertical imbalance create or compound for a child under 5 years old?

    Visually:

  • •What problems can a vertical imbalance create or compound for a person in kindergartener to 2nd

    grade?

    •What problems can a vertical imbalance create or compound for a person reading chapter books?

    •What problems can a vertical imbalance create or compound for a person learning to read music and/or play an instrument?

    Visually:

  • •What problems can a vertical imbalance create or compound for a person involved in sports?

    •What problems can a vertical imbalance create or compound for a person that is a gamer?

    •What problems can a vertical imbalance create or compound for an adult?

    Visually:

  • • Look directly your hand and feel corner of wall. Is it straight? Put ambient lenses on. •What does the corner of the wall look like? • Look at your hand and feel the corner of the wall.

    What does it look like? What does it feel like? • Intellectually one knows that it is straight but their

    eyes now tell them and their touch agrees that the wall is curved. • The visual input overrides the tactile information at

    hand. •Vision guides motor.

  • Patient Questionnaire Alderwoodvisiontherapy.com/patientforms/

  • What tests and/or findings are helpful to gain information regarding a vertical imbalance?

    • Cover Test: distance and near

    • EOM: range

    • Vertical and horizontal deviation distance and near

    • Vertical and horizontal range distance and near

    • Accommodation

    • Stereopsis

    • Suppression

    • Sensory Motor Evaluation

  • Worth 4 Dot

  • Preschool Tests

  • Dinosaur Stereopsis Test for Preschoolers

  • How can a sensory motor evaluation (SME) be helpful to you in planning vision therapy?

  • SENSORY MOTOR EVALUATION/BROCK STRING

  • Nerve palsies and their impact on vision therapy

  • Exam Forms

  • Prism Adaptation Test • If no area of fusion, compensatory prism may aid

    fusion so that visual ranges, flexibility and sustaining skill can be developed through vision therapy •Trial minimal power of prism in trial frame for 30

    minutes in the reception area and then retest. Can you reduce the amount of prism power and maintain fusion?

    • If prism helps gain fusion, prescribe minimal prism to gain fusion to use in conjunction with vision therapy. • CAUTION!!! If more prism power is needed at the end

    of 30 minutes, avoid prism. Using compensatory prism may be problematic and patient may continually adapt need more power.
