PART 2

Why the 2026 Assessment Was Not Clinically Appropriate

Part 2 explains why the 2026 assessment was not clinically appropriate. It sets out the neurological nature of the young person’s impairment, the specialist baseline that guided their care for more than three decades, and the methodological errors that led to clinically impossible findings. This section forms the foundation for understanding the safeguarding and governance concerns that follow.

2.1 — The Nature of the Young Person’s Impairment

 

The young person’s visual impairment is neurological, not ocular. This distinction is fundamental to understanding why the 2026 assessment was not clinically appropriate.

 

A neurological visual impairment arises when the brain’s visual pathways are damaged. In this case, the injury occurred in childhood and resulted in:

  • permanent disruption of eye‑movement control
  • vertical nystagmus that does not fluctuate
  • impaired spatial awareness
  • reduced functional vision in real‑world environments

These features were documented consistently by a specialist over a 30‑year period, forming a stable clinical baseline. This baseline is not speculative — it is the product of decades of specialist neuro visual assessment, using methods designed specifically for neurological impairment.

 

Neurological visual conditions do not behave like routine eye conditions. They do not “come and go”, they do not “resolve”, and they do not fluctuate in the way ocular conditions sometimes can. They are permanent, non‑variable, and functionally significant.

 

Because of this, the young person has always required:

  • specialist neuro visual assessment, not routine optometry
  • functional‑vision evaluation, not standard sight tests
  • interpretation by clinicians trained in neurological impairment
  • continuity of care, because the baseline is essential for safety

Routine optometry — including WGOS‑standard assessments — is designed to measure ocular function: refraction, acuity, lens power, and general eye health.

 

It cannot measure:

  • neurological nystagmus
  • impaired eye‑movement control
  • visual‑processing deficits
  • spatial‑awareness impairment
  • functional‑vision limitations

These require specialist methods that were used consistently for three decades.

The 2026 assessment did not use those methods. It assessed the young person as though they had a routine ocular condition, not a neurological injury.

 

This mismatch between condition and method is the foundation of the clinical inappropriateness that follows in the rest of Part 2.

2.2 — Why Routine Optometry Was Inappropriate

 

The 2026 assessment was carried out using routine optometric methods. These methods are designed for ocular conditions — issues with the eyes themselves — such as refractive error, lens changes, or general eye health.

 

They are not designed to assess neurological visual impairment.

This distinction is critical. Routine optometry measures:

  • visual acuity
  • refraction
  • lens power
  • ocular alignment
  • general eye health

These tests assume that the brain’s visual pathways are functioning normally.

In the young person’s case, they are not.

 

The impairment is neurological, caused by early‑life injury to the visual pathways. This affects:

  • eye‑movement control
  • vertical nystagmus
  • spatial awareness
  • visual processing
  • functional vision in real‑world environments

None of these can be measured with routine optometric tools.

Why routine optometry cannot assess neurological vision

 

Neurological visual impairment requires:

  • specialist neuro visual testing
  • functional‑vision evaluation
  • analysis of eye‑movement control
  • assessment of visual‑processing ability
  • interpretation by clinicians trained in neurological conditions

Routine optometry does not include these methods. It cannot detect:

  • neurological nystagmus
  • impaired pursuit and saccadic control
  • spatial‑awareness deficits
  • visual‑processing limitations
  • functional‑vision impairment

These are the core features of the young person’s condition.

The 2026 clinician used the wrong clinical framework

 

By applying routine optometric methods to a neurological condition, the clinician:

  • assessed the wrong system
  • used tools that cannot measure the impairment
  • interpreted neurological symptoms as if they were ocular
  • produced findings that contradict the established baseline
  • created a misleading clinical record

This is not a minor technical issue. It is a fundamental mismatch between:

  • the nature of the impairment, and
  • the method used to assess it.

Why this matters

 

When the wrong clinical framework is used:

  • neurological impairment appears “variable” when it is not
  • permanent features appear “intermittent” when they are not
  • functional limitations are missed
  • safeguarding needs are underestimated
  • the clinical record becomes inaccurate
  • the young person’s safety is compromised

The 2026 assessment did not fail because of a single error. It failed because it used a methodology that was never capable of assessing the condition in the first place.

 

This is the foundation of the clinical inappropriateness that unfolds in the sections that follow.

 

With the limitations of routine optometry established, the next section sets out how these methodological errors directly affected the 2026 assessment and led to conclusions that could not be clinically correct.
