Visual system injury claim
Vision injury after a motor accident
A motor accident can injure the globe, retina, optic nerve, ocular muscles or visual pathways in the brain. Blurred vision is not one diagnosis and loss of sight is not assessed from a claimant estimate. Clauses 6.242-6.243 require an ophthalmologist to measure the visual system using AMA4 Chapter 8 and the correction normally worn before the accident.
Accident mechanism and diagnosis
How can this injury happen in a motor accident?
Airbag, glass or facial impact
Direct trauma may cause corneal injury, lens dislocation, retinal damage, globe rupture or orbital fracture affecting eye movement.
Head injury or optic nerve trauma
Rapid force, skull fracture or intracranial injury may damage the optic nerve, optic chiasm or visual pathways.
Vascular or pressure complication
Trauma can produce retinal vascular injury, haemorrhage or pressure-related damage requiring urgent ophthalmology care.
The injuries that may actually occur
- corneal scar or irregularity
- traumatic cataract or lens dislocation
- retinal tear, detachment or haemorrhage
- optic neuropathy or visual pathway injury
- orbital fracture with restricted eye movement or diplopia
- loss of an eye or severe globe injury
Symptoms and functional effects to document
- reduced near or distance vision
- missing areas of visual field
- double vision or difficulty tracking
- light sensitivity, glare or poor contrast
- depth-perception and mobility problems
- reading, screen, driving and work-safety limitations
Urgent health warning
Sudden loss of vision, a curtain or shower of floaters, severe eye pain, a distorted pupil, penetrating injury or new double vision after a crash requires urgent medical assessment.
Medical evidence
What tests and findings matter?
The ophthalmology diagnosis and repeatable measurements should match the claimed functional loss. Neurological visual loss may also require neuro-ophthalmology, imaging and brain-injury evidence.
| Test or record | What it can establish | What it cannot establish alone |
|---|---|---|
| Best-corrected visual acuity | Measures near and distance central vision using the correction ordinarily worn before the accident. | Uncorrected blur or one inconsistent chart result does not establish permanent visual WPI. |
| Formal visual field testing | Maps repeatable peripheral or central field loss and can identify optic nerve, retinal or brain-pathway injury. | A subjective confrontation test alone may be insufficient for permanent field quantification. |
| Ocular motility and diplopia assessment | Documents restricted movement, misalignment and the positions in which double vision occurs. | Intermittent blur is not the same as measured diplopia or ocular-motor impairment. |
| Slit-lamp, retinal and optic imaging | Identifies corneal, lens, retinal, orbital or optic-nerve pathology and tracks treatment response. | An image finding must be causally linked and functionally assessed; it does not set WPI alone. |
A separate legal classification
Threshold injury is not the same as WPI
A diagnosed injury to the eye, optic nerve, retina, orbital structures or central visual pathways may support a non-threshold physical injury. Visual symptoms caused only by a soft tissue injury, medication or an unsupported complaint require separate analysis. WPI is a later and different measurement.
A non-threshold classification does not set a WPI percentage. Conversely, a low or zero WPI assessment does not necessarily decide the threshold-injury classification. Physical and psychiatric WPI are assessed separately and cannot be combined to determine whether impairment is greater than 10%.
Motor Accident Guidelines Part 6
How is permanent impairment assessed?
Under clauses 6.242-6.243, an ophthalmologist applies AMA4 Chapter 8. The relevant components can include corrected central visual acuity, visual fields and ocular motility or diplopia. AMA4 Chapter 8 then converts the supported visual-system impairment to WPI. The assessor must account for a first or different post-accident correction rather than rating avoidable uncorrected blur.
| Assessment issue | CTP method | Important limit |
|---|---|---|
| Central vision | Measure best-corrected near and distance acuity under AMA4 Chapter 8. | The correction ordinarily worn before the accident is the starting point under clause 6.243. |
| Peripheral or central field loss | Use reliable formal visual-field results and the Chapter 8 field method. | Poor reliability indices or inconsistent fields require explanation before rating. |
| Diplopia and ocular motility | Assess repeatable double vision and movement loss under the applicable Chapter 8 method. | Symptoms are not added again if already represented in the same visual-system loss. |
What may result in 0% or no assessable WPI?
- temporary blur that resolves or is fully corrected back to the pre-accident state
- subjective visual difficulty without reproducible ophthalmic or neuro-ophthalmic findings
- an incidental eye condition not caused or worsened by the accident
- a test result that is unreliable and not supported by the clinical picture
What may support a higher assessment if verified?
- permanent loss of corrected central acuity
- reproducible visual-field loss affecting functional vision
- persistent diplopia or ocular-motor restriction under the Chapter 8 method
- loss affecting both eyes or multiple visual functions where the method permits their integration
Combination and overlap rules
- The visual-system components are integrated using AMA4 Chapter 8 rather than simply adding test percentages.
- Facial scarring, cranial nerve injury or brain injury may use separate methods only where distinct impairment remains and overlap is avoided.
- Psychiatric WPI from adjustment to vision loss is assessed separately and cannot be combined with physical WPI to pass the greater-than-10% test.
What does not establish impairment by itself?
- blurred vision reported without ophthalmology measurements
- a scan abnormality without matching visual loss
- wearing stronger glasses by itself
- one unreliable visual-field test
Crash-specific examples
Orbital fracture with double vision
CT identifies the fracture, while ophthalmology measures ocular movement and diplopia after treatment. The fracture image alone does not set visual WPI.
Optic nerve injury after head trauma
Serial acuity, fields, optic imaging and neuro-ophthalmology opinion help connect the crash to permanent loss and distinguish it from pre-existing eye disease.
Claim file preparation
Evidence checklist
Practical next steps
What should you do next with a vision injury after a motor accident claim?
Start with the insurer's most recent written decision and identify what is actually disputed: treatment, weekly payments or work capacity, threshold injury, permanent impairment, causation, or damages. These are separate questions and may require different evidence and review procedures. Record the date of the decision and every review deadline shown before gathering further material.
- 01
Preserve the claim and the decision under review
Keep the claim number, accident date, insurer letter, certificate of fitness and any internal review or Personal Injury Commission correspondence together. Do not assume that a treatment approval or payment of statutory benefits decides fault, damages eligibility or WPI.
- 02
Obtain evidence that answers the disputed issue
For this injury, the useful starting material includes emergency and ophthalmology records from the first visual change and best-corrected near and distance acuity results. Clinical testing may include Best-corrected visual acuity and Formal visual field testing. Ask the treating practitioner to record the diagnosis, accident causation, objective findings, treatment response and current functional limits rather than symptoms alone.
- 03
Use the correct review process
Compare the insurer's reasons with the records it relied on. A threshold-injury decision, treatment refusal, weekly-payment decision and WPI assessment do not all follow the same review process. The decision letter should identify available internal review or dispute steps and the applicable deadline.
If the decision, medical material or deadline is unclear, send the key documents for a focused review before lodging a broad objection. See the CTP disputes guide or contact NSW CTP Claim. Advice depends on the facts, evidence and current law; a review cannot guarantee a claim outcome.
Assessment source
Visual-system assessment under the NSW CTP Guidelines
Assessment source: Motor Accident Guidelines Part 6, clauses 6.242-6.243; AMA4 Chapter 8 (pages 210-222), including the applicable visual-system conversion method.
Threshold injury: A supported structural eye, optic nerve or central visual injury may be non-threshold; symptoms and WPI must still be assessed separately.
What the assessor checks
- assessment by an ophthalmologist
- usual pre-accident correction
- corrected acuity, fields and ocular motility as applicable
- causation and reliable repeatable results

- subjective blur
- uncorrected acuity alone
- an incidental scan finding
- one unreliable field result

Frequently asked questions
- Who assesses visual WPI in a NSW CTP claim?
- Clause 6.242 requires assessment by an ophthalmologist.
- Is vision assessed with or without glasses?
- The assessment uses the correction ordinarily worn before the accident. If the crash caused a first or different correction, the difference is accounted for.
- Does a normal eye scan rule out visual impairment?
- No. Acuity, fields and ocular motility can identify functional visual loss, but the findings must be reliable and causally related.
- Can diplopia be part of WPI?
- Yes, where persistent double vision and ocular-motor findings satisfy the applicable AMA4 Chapter 8 method.
- Does permanent vision loss automatically establish damages?
- No. Statutory benefits, threshold classification, WPI and common law damages each have separate legal requirements.
