  1. BINOCULAR DYSFUNCTION REMEDIATION I ACCOMMODATIVE THERAPY

  2. Accommodative Dysfunctions • Run along the vertical axis of the new fangled, BVA ‘O’ MATIC CHART • Less severe: towards center • More severe: towards periphery

  3. AE PCE 2ºAE LOW/ NORMAL HIGH/ NORMAL CE CI LOW HIGH HIGH/ NORMAL LOW/ NORMAL PCI PCE 2ºAI AI

  4. Accommodative Dysfunctions • Off vertical axis: increased vergence involvement • Left: PCI or CI • Right: PCE (secondary to accommodative excess or insufficiency)

  5. AE PCE 2ºAE LOW/ NORMAL HIGH/ NORMAL CE CI LOW HIGH HIGH/ NORMAL LOW/ NORMAL PCI PCE 2ºAI AI

  6. Accommodative Insufficiency (AI) • More severe at bottom edge • Vergence is a secondary modality to address • 5 accommodative activities first 2-3 sessions • Incorporate 2 vergence activities after 2rd session

  7. Accommodative Excess (AE) • More severe at top edge • Usually expect smaller “gains” each week of Tx compared with insufficiency • Vergence is a secondary modality to address • 5 accommodative activities first 3-4 sessions • Incorporate 2 vergence activities after 3rd session

  8. Accommodative Infacility (AInf) • Towards periphery (usually a older, more severe cases) • Top: “Classic” accommodative infacility • Diagnostic criteria for AE PLUS • Difficulty clearing MINUS (and plus) on monocular +/-2.00 facility • Takes longer to remediate than other accommodative Dx

  9. Accommodative Infacility • Towards periphery (usually a older, more severe cases) • Bottom: accommodative infacility with accommodative insufficiency • Diagnostic criteria for accomm. insufficiency AND... • Difficulty clearing PLUS (and minus) on monocular +/-2.00 facility • Takes longer to remediate than AE and AI, but shorter than true infacility

  10. Therapy Techniques for Accommodation Tx • Monocular Hart Chart Rock: • Monocular Lens Rock: • Monocular window screen rock: • Alternate occlusion methods (lens rock or far/near rock): • *Red/Red Rock: • *Binocular A/S Chart Rock:

  11. Vergence Techniques for Accommodation Tx • Brock string: • Add ladybug vergence • Add BI/BO flippers • Add BOP/BIM

  12. Vergence Techniques for Accommodation Tx • Vectogram: • Add spatial localization • Add BI/BO flippers • Add BOP/BIM • Eccentric circles: • Add spatial localization • Add BI/BO flippers • Add BOP/BIM

  13. Tips For Vision Therapy
