The task

Assume that today's date is 22 October 2026. You have just completed Mrs Bhatia's annual diabetic eye examination.

You are an optometrist in a community optometry practice.

Address the letter to Dr Suresh Trivedi, General Practitioner, 45 King Street. In your answer: expand the relevant notes into complete sentences; do not use note form; use letter format.

Case notes

Patient details

  • Name: Mrs Orla Bhatia
  • DOB: 14/03/1977 (49 yrs)
  • Address: 8 Elm Avenue
  • GP: Dr Suresh Trivedi; attends practice yearly for diabetic eye exam

Social background

  • School administrator, full-time; long hours, irregular meals
  • Married, 2 teenage children
  • Enjoys gardening and sings in local choir
  • Says husband 'keeps nagging her about sweets' and they argue about it

Medical history

  • T2DM dx 2019 — metformin
  • Hypertension — perindopril
  • Hypothyroidism — thyroxine, stable
  • Appendicectomy 1995
  • Allergies: NKDA

Ocular history

  • Last exam 10/2025: no diabetic retinopathy; mild myopia, glasses for distance
  • Wore soft contact lenses in her 20s; now glasses only
  • Father had cataract surgery aged 70

History today

  • Occasional blurred distance vision, varies day to day, past 2/12
  • Reports home BGLs often 'in the teens'; admits control poor; missed last 2 GP appts
  • Unsure of latest HbA1c result
  • Pt critical of GP clinic: 'impossible to ever get an appointment there'
  • Complained about cost of new frames last year

Examination

  • VA with current specs: R 6/6, L 6/6
  • Refraction: small myopic shift both eyes since 10/25 — not prescribed (likely due to fluctuating BGLs)
  • IOP within normal limits both eyes; anterior eyes healthy
  • Dilated fundus: scattered microaneurysms only both eyes; no retinal haemorrhages
  • OCT macula: no oedema; no maculopathy either eye
  • Retinal photos taken — copy available for GP

Assessment

  • Mild non-proliferative diabetic retinopathy (NPDR) both eyes, no maculopathy — new since last exam
  • Blurred vision likely fluctuating refraction from hyperglycaemia, not retinopathy

Plan

  • Findings explained; advised good BGL + BP control ↓ risk of progression
  • Advised to report promptly any sudden ↓ vision, new floaters or distortion
  • Recall 12/12 for dilated exam + OCT; earlier if symptoms
  • Recommend GP review of glycaemic and BP management
  • Re-check refraction once BGLs stable; new specs then if needed
  • Pt intends to book GP appt this week

Who is reading, and what do they need?

Dr Trivedi is the GP managing Mrs Bhatia's diabetes and hypertension. He may not know retinopathy has appeared, and he must act on a request to review glucose and blood pressure management. He needs clear findings, what explains the blurred vision, and follow-up plans, in plain terms without ocular detail.

What to include

Selection is the skill the Content and Conciseness criteria reward. These notes earn their place:

Case noteWhy it belongs
Mild NPDR both eyes, no maculopathy; new since last exam 10/2025This is the main finding and the reason for writing. The change from no retinopathy last year makes it relevant.
Scattered microaneurysms only; no retinal haemorrhages; OCT no oedemaThese findings support the grading and show no maculopathy, in a concise form the GP can use.
Blurred vision likely fluctuating refraction from hyperglycaemia, not retinopathyThe GP needs to know the symptom's likely explanation, which links to glycaemic control. Keep the hedging as the assessment states it.
Home BGLs often 'in the teens'; admits control poor; unsure of latest HbA1cThis is the patient's own report and the basis for the recommended glycaemic review.
Missed last 2 GP appts; intends to book appointment this weekIt is relevant to follow-up. Word it neutrally, together with her stated intention to book.
Hypertension on perindopril; T2DM on metforminMedicines connect to the recommended review of glycaemic and BP management. Keep it brief as the GP already knows them.
Advised to report sudden ↓ vision, new floaters or distortion; recall 12/12This shows what advice she has and the follow-up arrangement, so the GP can reinforce it.
Retinal photos available; re-check refraction once BGLs stableThe GP can request the photos, and the refraction plan explains why no new spectacles were prescribed.

What to leave out or compress

Case noteWhy it goes
Says husband 'keeps nagging her about sweets' and they arguePrivate family conflict with no role in the findings or requests, and it may sound judgemental.
'Impossible to ever get an appointment there'Trap: it seems linked to her missed appointments, but it is a complaint about the GP's clinic and including it would be tactless.
Complained about cost of new frames last yearA past comment about cost has no bearing on this update.
Father had cataract surgery aged 70; soft contacts in her 20sOld or family eye history that does not affect today's findings or the requests.
School administrator, irregular meals; choir; gardening; two teenagers; appendicectomy 1995Social colour and unrelated surgery. Do not use job or meals to suggest a cause that the notes do not state.
VA 6/6 both eyes, IOP normal, anterior eyes healthy; hypothyroidismCompress to a very short mention at most. They are normal or stable and do not change what the GP does.

A paragraph plan for this case

Open with the purpose of the update and today's annual examination, then give the new retinopathy finding with the contrast to last year and the explanation for the blurred vision. Follow with her reported glucose control and appointments, then the advice given, recall and the specific recommendation for the GP.

Where candidates slip on this task

  • Do not attribute the blurred vision to retinopathy. The assessment says it is likely fluctuating refraction from hyperglycaemia, and the changed prescription was not issued for that reason.
  • State clearly that the retinopathy is new since October 2025 and that there is no maculopathy. Do not drop either detail, and do not suggest progression is certain or impossible.
  • The notes record a dilated examination but give no after-dilation advice, so do not invent any. Do not blame the patient for missed appointments or quote her criticism of the practice.

Questions about this task

Do I include her complaint about getting GP appointments?

No. It is criticism of the recipient's clinic and is not clinically useful. The relevant facts are that she missed two appointments and intends to book one this week.

Can I state her HbA1c?

No. No result is on the card and she is unsure of her latest one. You can mention her reported home readings and recommend a review of glycaemic management.
