Blepharitis
A free high-yield preview for the UKMLA Applied Knowledge Test. Below are the key points to recognise blepharitis — the full SA Note notes add investigations, management, complications and 10 practice questions.
Key high-yield points
- Bilateral chronic grittiness, soreness, burning of eyelid margins
- Sticky eyes in the morning - secretions and crusts accumulate overnight
- Red eyelid margins - redness localised to lid edge, not the conjunctiva
- Dry eye symptoms - paradoxical watering from reflex tearing
- Vision is not affected - any visual acuity change should prompt urgent alternative diagnosis
- Associated conditions: hypothyroidism (meibomian gland dysfunction), rosacea, seborrhoeic dermatitis
Chronicity (months to years, bilateral) distinguishes blepharitis from acute conjunctivitis. Itch is less prominent than in allergic conjunctivitis.
