Ophthalmology OSCE Stations: The Complete List and How to Approach Each

Ophthalmology OSCE stations are not a finite official list. The mix, timing and marks change between examining bodies and programmes. What repeats is the task family: examine, perform, interpret, communicate or defend a focused decision. The most reliable approach is a fixed opening, a task-specific middle, and a disciplined close. This guide is for postgraduate examination practice, not a protocol for patient care.

The 15-second read that prevents a lost station

Before you touch a chart, patient or instrument, identify four words in the task: action, target, setting and output. “Demonstrate applanation tonometry and explain the result” is different from “interpret this field” and different again from “counsel a patient before a procedure.” Candidates often perform a good examination and receive poor marks because they answer a nearby question instead of the question on the card.

Use this opening every time it fits the station:

1. Introduce yourself and confirm the relevant identity details.
2. Explain the focused task in plain language and obtain consent where a simulated patient is involved.
3. Check comfort, position, illumination, relevant infection-control measures and any local chaperone requirement.
4. State that you would compare both eyes or obtain the fellow-eye context when appropriate.
5. Perform only what the task asks, then describe, interpret and close.

The RCOphth curriculum and its OST Curriculum Handbook describe broad training capabilities, but neither is an official blueprint for every Indian university or DNB / MS / DO practical. Check your own current candidate instructions first.

The universal five-minute operating sequence

This time plan is a rehearsal tool, not an examination rule. Adapt it when your station timing differs.

If the examiner interrupts, stop and answer. Continuing a memorised script after a new question is a common timing error. If equipment is missing or a patient cannot cooperate, say what you would do next and why; do not silently improvise a different station.

The station-family map

Practise the families rather than memorising dozens of titles. A new station almost always belongs to one of these groups.

No row above is a promise that it will appear in your exam. It is a practice map that lets you prepare for an unfamiliar stem without acting as if every station demands the same full examination.

Script one: examination stations

An examination station needs a visible order. Your spoken language should reveal decisions the examiner cannot see, but it should not become a commentary track.

The examine–describe–interpret sequence

Examine. State the focused preparation: “I would ensure appropriate position and illumination, explain the examination, and compare the other eye where relevant.” Then use the recognised sequence for that test.

Describe. Use laterality, location, size or grade where relevant, and positive findings before conclusions. For example, a formal slit-lamp presentation can move from lids and conjunctiva to cornea, anterior chamber, iris and lens. A fundus presentation can move through media, disc, vessels, macula and periphery. The task may not need every normal structure; state only what creates a coherent answer.

Interpret. Offer a limited conclusion linked to evidence: “The key feature is X, which raises Y; I would correlate it with Z.” Avoid a theatrical differential of ten diagnoses. In a timed station, two justified possibilities are stronger than an unranked list.

Visual acuity, pinhole and refraction records

Examiners are often scoring discipline rather than your ability to name a chart. Check the correct testing distance and whether testing is unaided, aided or pinhole. Test one eye at a time and record the result exactly in the convention your programme uses. If pinhole changes the result, explain what that suggests about an optical component; do not proclaim a final diagnosis from that fact alone. If the candidate or simulated patient cannot complete the test, document the limitation instead of inventing a number.

Slit-lamp examination

Have a sequence before you enter the room. Start with external inspection, then move deliberately through the ocular surface and anterior segment. Alter magnification, beam width, height, angle or illumination only when it answers the question. The common failure is to say “normal anterior segment” after looking briefly through a broad beam. The better viva phrase is: “I would use an appropriate beam to inspect the cornea and anterior chamber, then describe any cells, flare, epithelial defect, infiltrate, oedema or lens change requested by the station.”

Tonometry and gonioscopy

Technique stations reward preparation. Explain what you would check before touching the eye, how you would position the patient, and how you would record the result. A tonometry reading is not an isolated diagnosis: corneal properties, technique, timing, symptoms and optic-nerve/field context may matter. In a gonioscopy station, describe the angle appearance systematically instead of jumping to a label. Where the station asks for a grade, use the classification your examiner specifies.

Fundus examination

Do not hunt only for the expected lesion. Start with laterality and media clarity, then use a reproducible route: optic disc, vessels, macula and peripheral retina as far as the method permits. If dilation or another step is required, explain that it requires appropriate consent and context. Your conclusion should include what you saw and what you could not assess. That limitation is a mark of safe clinical reasoning, not a weakness.

Script two: image and investigation interpretation

Interpretation stations are frequently lost in the first sentence. Candidates name a disease immediately, before checking whether the image is labelled, centred, reliable or even from the eye they think it is.

Use Q–P–L–D–C:

1. Quality: identify patient, laterality, modality and reliability/artefact where visible.
2. Pattern: describe the actual structural or functional pattern.
3. Localisation: say where the pattern sits anatomically or functionally.
4. Differential: give the most plausible interpretation and one sensible alternative if required.
5. Correlation: state what examination, history or paired investigation would support it.

Visual fields

Begin with test quality and reliability indices if provided. Then describe whether the defect is focal or diffuse, its relationship to the horizontal or vertical meridian, and whether the pattern is consistent across eyes. “Inferior arcuate defect” demonstrates more than “glaucoma field.” Do not overcall a single printout: say what correlation with disc, OCT, IOP history or repeat testing would be relevant if the station asks for next steps.

OCT, FFA and fundus photographs

Name the modality and scan orientation. On OCT, describe the retinal layers or contour before attaching a disease label. On FFA, distinguish timing from leakage, staining, blockage or non-perfusion language only when those features are visible. On a photograph, place the lesion by disc/macula/periphery and use morphology. An examiner can award marks for observation even if your final diagnosis needs refinement.

Biometry, topography and ultrasound

These stations often test whether you respect test limitations. First establish which eye and which measurement is displayed. Next identify the pattern relevant to the question, then say what quality or corroboration you would need. Do not offer a definitive lens choice, surgical plan or management instruction from an isolated image in an exam-practice article.

Script three: communication and consent stations

Communication is not a softer station. It tests whether you can turn specialist language into a structured, respectful conversation while recognising uncertainty. The GMC’s Decision making and consent guidance is a useful professional reference for the principles of dialogue, material information and questions; local rules and the patient’s circumstances control real practice.

Use A–G–E–N–D–A:

Avoid false reassurance. “This is nothing to worry about” is usually indefensible when the vignette is incomplete. Better: “I can see this is worrying. I will explain what we know, what remains uncertain, and what information the team needs before deciding the next step.” In a communication OSCE, use the task information supplied. Do not invent a complication, a risk percentage or a guarantee to sound comprehensive.

How to approach common practical prompts

“Show me how you would examine for a RAPD”

The marks usually sit in preparation, comparison and observation. Explain the task, use an appropriate lighting environment, compare direct and consensual responses, perform the swinging-light manoeuvre in a controlled way, and state what pattern you are seeking. Do not simply name “RAPD” after moving the light. If the station asks for causes, give a focused afferent-pathway differential rather than a generic list of red-eye diagnoses.

“Perform a cover test”

Fixation target, distance/near context, cover–uncover versus alternate cover logic, and observation of movement are the essentials. State whether you are looking for tropia, phoria or change with dissociation. If measurement is requested, use the unit and method required by your programme. A cover test can be beautifully performed and still poorly presented if you omit whether the finding was for distance or near.

“Assess a patient with proptosis”

Look before you touch. Observe facial asymmetry, globe position, lids, surface exposure, pupils, motility and optic-nerve-related concerns. Explain what measurements and comparisons you would make. Acknowledge red flags in an examination answer, but do not write a patient-specific treatment plan. The examiner is usually assessing whether you recognise that orbital assessment is wider than exophthalmometry alone.

“Identify this instrument or drug”

Use a four-part answer: exact name, one identifying feature, purpose and one safety/care point. If uncertain, describe the object first rather than guessing a brand. For a drug, add class and the key adverse-effect clue; exact real-world dose verification belongs to authorised product information, not memory alone. This approach works particularly well in mixed practical/viva circuits.

The examiner-facing checklist

Peers often mark too generously because they know what you meant. Use an observable checklist instead. A simple station scorecard can have six domains:

For each domain, score “not seen”, “incomplete” or “clear”. Write one specific feedback line: “You named the field defect before checking reliability,” not “be more confident.” A video of a timed practice station can reveal silent gaps, but use it only with consent and respect for privacy.

A one-week OSCE circuit for residents on duty

The goal is retrieval under a clock, not a marathon of passive checklists. Keep each practice block short enough to survive OPD and night duty.

After every station, write a single “next repetition” instruction. Examples: “say test distance before visual acuity,” “describe field reliability first,” or “stop when interrupted.” Rehearse that correction in the next circuit. Repeating a station that already feels fluent is comforting but has a low return.

Eight errors to remove before the next mock

1. Beginning the examination before reading the task verb.
2. Forgetting laterality, test conditions or a comparison eye.
3. Describing a diagnosis without visible supporting findings.
4. Treating a low-quality investigation as diagnostic.
5. Performing a whole examination when the task asks for one manoeuvre.
6. Using jargon in a communication station without checking understanding.
7. Offering a definitive management plan from incomplete station information.
8. Continuing after an examiner has redirected you.

For structured practical practice, the OSCE, Practical & Viva Voce Ready bundle is the relevant OphthaMCQ route. Pair practical work with the DNB Ophthalmology preparation guide when you are balancing theory and practical revision, and use the ophthalmology glossary to close terms that repeatedly stall a viva. A case-presentation template can also help you rehearse concise summaries; see Case Presentation Format Notes.
