Scope
The Bottom Line
- Assess pain, photophobia, vision change, contact-lens use, trauma, chemical exposure, discharge, pupil and corneal appearance.
- Measure visual acuity in each eye where possible because external redness alone does not define severity.
- Use fluorescein and other examination techniques only when trained and interpret them with the referral pathway.
- Do not start topical corticosteroid for an undifferentiated red eye without ophthalmic advice.
Practical clinical workflow
Safety boundaries and escalation
- Reduced vision, severe pain, fixed or irregular pupil, corneal opacity, penetrating trauma or acute-glaucoma features requires emergency ophthalmology.
- Chemical injury requires immediate prolonged irrigation and urgent specialist advice.
