Case Presentation Format for the Ophthalmology Practical Exam

An ophthalmology practical case presentation is a clinical argument in a fixed order: state the problem, give the findings that support it, then say what is still uncertain. A reliable default is one-line summary → focused history → reproducible examination → positive findings and relevant negatives → provisional diagnosis and differential → targeted discussion. It is stronger than reading a complete clerking aloud because it lets the examiner see how each fact changes your thinking.

This is a postgraduate examination rehearsal framework for doctors. It is not a local marking scheme, a substitute for supervision, or a management protocol for an individual patient. Your university may prescribe different headings or time limits. Keep its required headings, but retain the reasoning order below.

Build the case around a problem representation

Before you start speaking, reduce the case to one sentence. Include only four things: the patient context, laterality, time course and syndrome. Add a discriminator only if it genuinely narrows the differential.

“This is a 62-year-old patient with painless, progressive reduction of vision in the right eye over two years, with examination localising the principal opacity to the lens. My provisional diagnosis is an age-related cataract; I would still correlate IOP, posterior-segment assessment and fellow-eye findings.”

That sentence does three jobs. It tells the examiner you have identified the dominant problem. It prevents you from prematurely naming a subtype. It also shows that you understand the boundary of the current examination. Do not fill it with details that do not change classification, severity or differential. “Known diabetic, hypertensive, no allergy, no fever” is not a problem representation unless those details are relevant to the observed eye disease.

Use the same structure in every specialty:

The clinical-method principle is simple: a presentation should communicate the history and examination reasoning, not reproduce the entire source record. Clinical Methods from NCBI Bookshelf is a useful general reference for the clinical-history framework; it is not an ophthalmology practical-exam rulebook.

Use a three-minute run-sheet, not a memorised essay

The order below works for most long cases. Mark your actual station time beside it during rehearsal; a three-minute example is only a training device.

Do not announce every heading as though reading an examination form. Use headings in your notebook; in the spoken presentation, join them with causal language. “There is no history of trauma” gains value when you add “which makes a traumatic lens change less likely in this case.” A negative without a diagnostic purpose is merely a longer presentation.

Decide what belongs in the history

The history should change one of five things: localisation, tempo, differential, complication risk or test interpretation. Work from the presenting complaint rather than from a generic systems checklist.

For visual loss, establish onset, course, laterality and functional impact. Ask pain, redness, photophobia, floaters, photopsia or metamorphopsia only when the syndrome makes them discriminating. Ocular history should include relevant trauma, surgery, injections, laser, contact-lens use, glasses and disease in the fellow eye. Systemic disease, medicines and family history belong when they alter the differential or interpretation. In a glaucoma case, steroid exposure, trauma, uveitis, pseudoexfoliation clues, pigment-dispersion history and family history are meaningful branches. In a cataract case, prior ocular inflammation, trauma and rapid symptom evolution may matter more than a long list of unrelated medication names.

Use a relevance test before you speak: if I remove this fact, does the differential, severity assessment or next investigation change? If the answer is no, omit it from the oral summary. Keep a longer record in case the examiner asks.

Relevant negatives are active evidence. Say “There is no pain, corneal oedema or shallow anterior chamber on the information available” only where those observations distinguish a complication you are considering. Never manufacture a negative because it appears in a textbook. If you did not assess a feature, say “I would specifically check…” rather than implying that it was normal.

Present the examination in a reproducible order

Examiners can follow an imperfect finding more easily than a disordered examination. Start with visual function, name the eye and method, then move from external observation to the compartment most relevant to the case. Finish with the fellow eye where appropriate. The exact sequence changes by syndrome, but your sequence should not change halfway through a case.

For a typical anterior-segment case, a useful order is general observation, visual acuity and refraction where relevant, external examination, pupils, slit lamp, IOP, dilated posterior segment if appropriate, then fellow eye. For posterior-segment disease, lead with visual function and media clarity before a structured fundus description. In glaucoma, make cornea/anterior chamber/lens clues, IOP method, gonioscopy, disc and field/OCT correlation explicit. In neuro-ophthalmology or orbit, inspection, acuity, colour/field testing where available, pupils, motility, optic nerve and localisation signs form a more natural sequence.

State the method and limit of a test. “IOP was 24 mmHg” is incomplete without the method in a formal presentation. “The view of the fundus is limited by media opacity” is better than pretending that an optic disc has been assessed. “The field is unreliable because …” is better than calling a defect from an unqualified printout. Precision about limits is not weakness; it is diagnostic discipline.

Convert observations into implications

Keep a private two-column note as you examine:

This approach prevents two common errors: a catalogue of signs with no conclusion, and a conclusion with no cited evidence. Give two or three decisive positives, then one or two negatives that genuinely separate the leading alternative.

Make the diagnosis a bounded claim

The safest diagnostic sentence has three parts:

“The most likely diagnosis is [condition] because of [two or three positive findings]. The principal alternative is [alternative]; I would distinguish it by [specific history, sign or test]. I cannot yet determine [uncertain subtype/severity/complication] because [limit].”

For example: “The most likely diagnosis is primary open-angle glaucoma because of the open angle, glaucomatous rim change and a concordant reliable field defect. A secondary open-angle mechanism remains a differential if the history or anterior-segment findings identify one. I would not call progression without comparable reliable serial evidence.” This format is appropriate because it connects diagnosis to the available evidence and resists overclassification.

Do not say “definitive” unless the station has supplied the necessary evidence. Do not turn “likely” into indecision either. A candidate who names the leading diagnosis, justifies it and identifies the missing discriminator sounds more clinically organised than one who gives a long, unranked differential.

Answer investigation questions by purpose, not by shopping list

When asked “What investigations would you do?”, first identify the question. Then name the investigation, what it would establish, and a limitation if relevant.

For viva, do not drift into a patient-specific treatment plan. Say “The examination discussion would then depend on the complete assessment, current local protocol and supervision.” This is both honest and appropriate for an education page.

Recover when the examiner interrupts

Interruption is usually a signal to discuss, not proof that the presentation has failed. Pause, answer the new question directly, then use a bridge back to the run-sheet:

• “That finding supports my working diagnosis because … . Returning to the examination, the next relevant point is …”
• “I do not have sufficient information to make that subtype claim. The discriminator I would seek is …”
• “I would separate those two possibilities using …”
• “The limit here is the unavailable/poor-quality test; I would not overinterpret it.”

Avoid defending a scripted order at the expense of the question. The examiner may deliberately move from the disc to gonioscopy, from a cataract to the fellow eye, or from history to prognosis factors. Treat each move as a request to reveal your logic.

Practise with a closed-book audit

After examining a case, prepare one page only. Present from it aloud, then compare it with the findings. Do not score how polished you sounded; score whether each claim had evidence.

Run the same case twice. In run one, speak normally. In run two, have a colleague interrupt after your history and after your diagnosis. That rehearsal exposes whether you understand the case or only remember the paragraphs. Use the OphthaMCQ case-presentation format resource if a fixed practical template would help your notebook; use the OSCE, Practical & Viva Voce Ready bundle for wider station practice. For topic-specific correlation before a glaucoma or cataract case, the verified on-site glaucoma study guide and cataract study guide are relevant revision routes. DNB candidates can also use DNB / MS / DO past five-year papers to identify recurring discussion themes.

Match the format to the case without losing the logic

A universal template is useful only if you can adapt it. In a retina case, the symptom-to-localisation bridge may deserve more time than an exhaustive external examination. In an orbital case, inspection and motility may come before slit-lamp detail. In a glaucoma case, leave time to describe the angle and demonstrate disc-field correlation. In a cataract case, do not rush past the cornea, chamber, pressure and limit of posterior view in order to announce a familiar lens label. The sections change in emphasis; the three-part logic does not: claim, evidence, uncertainty.

This also helps with a deliberately incomplete station. If an examiner gives an image but no field printout, say what the image supports and what it cannot settle. If a pressure measurement has no method, report the value as supplied and identify the missing context. If a patient cannot complete a test, distinguish an unavailable result from a normal result. These phrases show that you understand evidence quality rather than merely missing a line from a script.

A final thirty-second close

When asked to conclude, do not repeat the whole history. Deliver a compressed assessment: “In summary, the principal syndrome is [X], supported by [A] and [B]. The immediate differential is [Y] because [discriminator]. The main unresolved point is [Z], for which I would seek [specific examination/test information].” This close gives the examiner an easy opening for a viva question and stops the presentation from fading into a generic management recital.

Your notebook should therefore contain two versions of every case: a full finding record and a three-minute argument. The full record protects accuracy; the short version trains order. Whenever a new fact changes the diagnosis, add it to the argument. Whenever a fact does not change the argument, retain it in the record but do not automatically speak it.
