The note that says "fundus normal - not dilated"

Duty. An optometrist–patient relationship existed, creating a duty of reasonable care in assessment, diagnosis and referral.

Breach. The standard is what a reasonably competent optometrist would do in these circumstances. Three points matter: (a) concluding "fundus normal" without dilation in a 54-year-old with small pupils and new daily headaches is difficult to defend; (b) transient visual obscurations in that setting are a recognised red flag for raised intracranial pressure and ordinarily require careful disc evaluation, ideally dilated, and a low threshold for referral; (c) "? migraine, reassure" with no review interval left the patient with no safety net. The failure may lie in the reasoning as much as in the omission.

Causation. Would timely disc assessment and referral more probably than not have led to earlier diagnosis and preserved field? That is the central factual dispute, and expert evidence will frame it. The likely defence is that progression was inevitable or that the patient would not have attended sooner.

Damage. Bilateral field loss is serious and quantifiable.

The record. A thin note does not by itself create liability, but it weakens the defence of clinical judgment, because the practitioner is usually the one who must show the care was given. The reception sticky note is also part of the file and cannot be discarded.

Do not manufacture a note. Writing "I checked the disc and it was fine" now - backdated, undated or otherwise - is a false record. If detected, and electronic metadata makes detection likely, it destroys credibility on every other issue and may itself be misconduct independent of the original care.

A legitimate addendum is different. You may add a new, dated and timed entry stating: reviewed on [date]; the record does not document disc assessment; I have no independent recollection beyond the note; any recollection I do have is as follows. Keep it factual and short, and tell the indemnifier it exists.

Preserve everything. Do not delete or "tidy" the reception sticky note; it is part of the clinical record and may be discoverable.

Responding to the lawyer. Route the request through your indemnifier. Release copies as authorised - usually on the patient's signed authority - retain the originals, and keep a disclosure log recording what was sent, to whom and when. Do not discuss the case with the patient's representatives or the employer, and do not contact the patient directly if he is represented. Notify your insurer before you reply, and follow its wording on any communication about the care.

1. A dilation protocol. Dilated disc assessment for new headaches, transient obscurations or unexplained visual symptoms, with consent and an angle check documented. Written protocols are the clearest evidence that the practice's standard matches the profession's.
2. Red-flag prompts in the record template that force a documented decision: disc seen? dilated? referred? reviewed by when? This converts a silent omission into a positive entry either way.
3. Closed-loop referral tracking - who books, who checks the letter was sent, who confirms the patient attended. The commonest failure in these cases is not the missed diagnosis but the referral that evaporated.
4. Written safety-netting at the end of the visit, copied to the patient.
5. Peer review of a sample of records for high-risk presentations.
6. A culture that permits uncertainty - "I am not sure, please come back or let me refer" - without loss of face.

Legally, these measures do two things: they make the correct action the default, and they generate the documentation that shows the practice's standard of care in any later claim. Remediation after the event is worth doing even when a complaint is already live, but it must be genuine, recorded and dated - not a page written for the file.
