BINOCULAR DYSFUNCTION REMEDIATION I ACCOMMODATIVE THERAPY

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

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

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

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

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

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

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

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