Direct ophthalmoscopy

Perform basic ophthalmoscopy and identify common abnormalities.

Target · Perform independently0% ready

Do it yourself on a patient, with support available if you need it — the GMC’s highest new-grad level (“indirect supervision”).

Overview

Fundoscopy — a discriminating FY1 skill and directly relevant to the ophthalmology-adjacent presentations (red eye, sudden vision loss). Master the systematic sweep: red reflex → optic disc → vessels → macula.

Indications

  • Assessing the red reflex (cataract, retinoblastoma in children)
  • Diabetic & hypertensive retinopathy
  • Papilloedema (raised ICP)
  • Sudden visual loss (central retinal artery/vein occlusion)

Contraindications & cautions

  • Avoid pharmacological dilation if angle-closure glaucoma is a risk, or where pupillary responses must be monitored (e.g. head injury) — always ask before dilating

Equipment

Direct ophthalmoscope (check the light and battery)Mydriatic drops (e.g. tropicamide 1%) if dilation permittedA darkened room

Step by step

Prepare
  1. 1Dim the lights; dilate the pupil if appropriate and consented
  2. 2Set the ophthalmoscope to 0 dioptres; ask the patient to fix on a distant point
Examine
  1. 1Use your right eye/hand for the patient’s right eye (and left for left)
  2. 2Elicit the red reflex from ~arm’s length
  3. 3Approach ~15° temporally, following a blood vessel back to the optic disc
  4. 4Assess the disc — colour, margins, cup:disc ratio
  5. 5Follow the four vascular arcades; assess AV nipping/haemorrhages/exudates
  6. 6Finally ask the patient to look at the light to view the macula

Complications

  • None significant; transient dazzle. Pharmacological dilation blurs vision for hours — warn re: driving.

OSCE tips

  • Right-to-right, left-to-left — getting the wrong eye/hand loses easy marks.
  • An absent red reflex is a red flag (cataract; leukocoria = retinoblastoma in a child).
  • Comment on the disc systematically; “I would ideally dilate for a full view” shows good practice.
