2.4A — Contradictions Matrix

A structured comparison of the 2018 specialist findings and the 2026 routine assessment, demonstrating why both cannot be correct

This section presents a structured contradictions matrix comparing the 2018 specialist neuro‑visual assessment with the 2026 routine optometric findings. Each contradiction is followed by the clinical reality and the governance implications. Together, they demonstrate why the 2026 findings are not clinically possible for a permanent neurological visual impairment.

Contradiction 1 — Vertical Nystagmus

2018 Specialist Finding: Vertical nystagmus present, consistent, permanent, and non‑fluctuating.

2026 Routine Finding: Nystagmus described as “intermittent”, “variable”, and “inconsistent”.

Why Both Cannot Be True: Neurological nystagmus does not come and go. It is constant and does not fluctuate.

Clinical Reality: If nystagmus appears “intermittent”, it was not measured correctly.

Governance Impact: The 2026 assessment misrepresents a permanent neurological feature, creating an unsafe clinical record.

Contradiction 2 — Eye‑Movement Control

2018 Specialist Finding: Permanent impairment of pursuit and saccadic control; no improvement possible.

2026 Routine Finding: Eye‑movement control described as “inconsistent” or “not present today”.

Why Both Cannot Be True: Neurological impairment of eye‑movement control does not resolve or vary between appointments.

Clinical Reality: Routine optometry cannot measure neurological eye‑movement impairment.

Governance Impact: The 2026 clinician interpreted neurological features through an ocular lens, leading to clinically invalid conclusions.

Contradiction 3 — Stability of Condition

2018 Specialist Finding: Condition stable, permanent, and non‑variable for over 30 years.

2026 Routine Finding: Condition described as fluctuating, with features appearing and disappearing.

Why Both Cannot Be True: Neurological visual impairment does not fluctuate. Variability indicates measurement failure.

Clinical Reality: The 2026 assessment used methods incapable of detecting neurological impairment.

Governance Impact: The 2026 findings undermine continuity of care and contradict the long‑term clinical baseline.

Contradiction 4 — Spatial Awareness

2018 Specialist Finding: Severe, permanent spatial‑awareness impairment affecting navigation and real‑world safety.

2026 Routine Finding: No spatial‑awareness issues identified.

Why Both Cannot Be True: Routine optometry cannot measure spatial awareness or functional vision.

Clinical Reality: The absence of findings in 2026 reflects the limitations of the test, not an improvement in the condition.

Governance Impact: Failure to identify spatial‑awareness impairment increases safeguarding risk.

Contradiction 5 — Functional Vision

2018 Specialist Finding: Functional‑vision limitations documented in detail, including fatigue, instability, and difficulty in complex environments.

2026 Routine Finding: No functional‑vision assessment performed; no functional limitations recorded.

Why Both Cannot Be True: Functional‑vision impairment cannot disappear simply because it was not assessed.

Clinical Reality: The 2026 assessment omitted the core domain of neurological visual impairment.

Governance Impact: The omission creates an inaccurate clinical narrative that minimises risk.

Contradiction 6

Nature of Impairment (Neurological vs Ocular)

2018 Specialist Finding: Impairment is neurological, permanent, and non‑recovering.

2026 Routine Finding: Findings interpreted as if the impairment were ocular and variable.

Why Both Cannot Be True: A neurological condition cannot behave like an ocular condition.

Clinical Reality: The 2026 clinician used the wrong clinical framework.

Governance Impact: The assessment method was inappropriate, making the findings clinically unsafe.

Contradiction 7 — Continuity of Care

2018 Specialist Finding: Assessment aligned with 30 years of consistent specialist evidence.

2026 Routine Finding: Assessment conducted without access to the 2018 report or the full clinical history.

Why Both Cannot Be True

A clinician cannot produce accurate findings without the baseline for comparison.

Clinical Reality: The missing 2018 report directly contributed to the errors in 2026.

Governance Impact: This represents a failure of record‑keeping, continuity, and clinical governance.

Contradiction 8 — Interpretation of Symptoms

2018 Specialist Finding: Neurological features interpreted correctly within a neuro‑visual framework.

2026 Routine Finding: Neurological features interpreted as ocular variability.

Why Both Cannot Be True: Neurological symptoms do not behave like ocular symptoms.

Clinical Reality: The 2026 clinician misinterpreted neurological signs due to inappropriate methodology.

Governance Impact: Incorrect interpretation led to unsafe conclusions and an inaccurate clinical record.

Contradiction 9 — Baseline Reference

2018 Specialist Finding: Findings consistent with the established baseline.

2026 Routine Finding: Baseline not accessed, referenced, or replicated.

Why Both Cannot Be True: A valid assessment must reference the established baseline for a permanent condition.

Clinical Reality: The 2026 assessment was conducted without essential clinical context.

Governance Impact: This breaks continuity of care and undermines the reliability of the record.

Contradiction 10 — Safeguarding Visibility

2018 Specialist Finding: Risks clearly documented and understood.

2026 Routine Finding: Risks minimised or not identified.

Why Both Cannot Be True: A permanent neurological impairment cannot become “low risk” due to a routine test.

Clinical Reality: The 2026 assessment failed to recognise functional‑vision risk.

Governance Impact

This creates direct safeguarding concerns.

This concludes Part 2. The contradictions identified across the clinical, functional, and governance domains make clear that the 2026 findings cannot be relied upon for any aspect of care or decision‑making. Part 3 now examines the wider systemic consequences — how these errors spread across services, how risk was amplified, and how the collapse of continuity created a multi‑layered governance failure.
