Subconjunctival haemorrhage
A free high-yield preview for the UKMLA Applied Knowledge Test, covering how to recognise this condition. The full SA Note notes add investigations, management and complications, with practice questions on this topic.
Key high-yield points
- Bright red patch on the conjunctiva - sharply defined edges, flat
- Asymptomatic in most cases - mild irritation or sensation of fullness possible
- Visual acuity normal - preserved VA distinguishes from sight-threatening red eye
- Pupil reactions normal - normal direct and consensual reflexes
- No discharge - distinguishes from conjunctivitis
- Colour change over time - red → green → yellow, resolves over 1-2 weeks
- Bilateral haemorrhage - raises suspicion of underlying bleeding disorder or systemic cause
Haemorrhage with no visible posterior margin after trauma = red flag for orbital roof or basal skull fracture. Requires urgent ophthalmology referral.
