OSCE Guide: Eye Examination
๐ Introduction
- ๐งผ Wash your hands before starting.
- Introduce yourself, confirm patientโs name & DOB.
- Explain: โIโd like to check your eyesight, eye movements, and back of the eye with a light.โ
- Gain informed consent and ensure comfort.
๐งฐ Equipment Needed
- Snellen chart ๐ (or equivalent, 6 m distance)
- Pen torch ๐ฆ
- Ophthalmoscope ๐๏ธ
- Near vision chart (optional, 33 cm)
๐ Step 1: General Inspection
- Look for facial asymmetry, abnormal head posture.
- Eyelids โ ptosis, swelling, redness.
- Conjunctiva โ injection, discharge.
- Sclera โ jaundice, vascular congestion.
- Cornea โ scars, opacities.
- Clinical pearl: Painful red eye with halos = acute glaucoma ๐จ.
๐ Step 2: Visual Acuity
- Snellen chart at 6 m (record as 6/6, 6/9, etc).
- Test one eye at a time (occlude, not press).
- If unable to read top line โ move closer, then CF (count fingers), HM (hand movements), LP (light perception).
- Repeat binocular vision if needed.
- Pearl: Always do VA before using drops, lights, or ophthalmoscope.
๐ฆ Step 3: Pupils
- Size, shape, symmetry.
- Light reflexes: Direct + consensual.
- Accommodation reflex: Constriction & convergence on near target.
- Clinical pearl: RAPD (swinging light test) โ optic nerve pathology (e.g. optic neuritis, severe glaucoma).
๐๏ธ Step 4: Extraocular Movements
- Ask patient to follow finger in an H-pattern.
- Check all 6 directions of gaze.
- Look for restriction, nystagmus, or diplopia.
- Pearl: CN VI palsy = failure of abduction; patient turns head towards lesion.
๐ Step 5: Visual Fields (Confrontation)
- Sit 1 m opposite, cover opposite eyes.
- Bring target in from periphery (4 quadrants).
- Patient says โnowโ when seen โ compare with your own field.
- Pearl: Bitemporal hemianopia = pituitary macroadenoma; homonymous hemianopia = stroke.
๐ Step 6: Ophthalmoscopy
- Dim lights, ophthalmoscope at 0 diopters.
- Approach from 15ยฐ temporal with same-side eye.
- Look for:
- Red reflex: absent in cataract/vitreous haemorrhage.
- Optic disc: margins (blurred in papilloedema), colour (pale in atrophy), CDR (raised in glaucoma).
- Vessels: AV nipping (HTN), microaneurysms (diabetes).
- Macula: look last (bright light uncomfortable) โ drusen in AMD.
๐งช Step 7: Extras (if time)
- Near vision (33 cm card).
- Colour vision (Ishihara plates).
- IOP (tonometry, specialist).
- Slit lamp (detailed anterior segment exam).
โ
Closure
- Thank patient, ensure comfort.
- Summarise findings: โVisual acuity 6/9 right eye, normal pupils, normal fields, fundus healthy.โ
- Wash hands ๐งผ.
- Document accurately.
โญ Key OSCE Tips
- Systematic: Inspection โ VA โ Pupils โ EOM โ Fields โ Fundoscopy.
- Always test VA first.
- Compare both eyes side by side.
- Communicate clearly, reassure often.
๐ซ Common Pitfalls
- Forgetting VA at start (examiners often deduct marks).
- Using incorrect Snellen distance.
- Not comparing fields to own normal.
- Poor positioning/lighting in fundoscopy.
