A child has fever, a swollen red eyelid, proptosis, pain on eye movement and reduced eye movements. What is the diagnosis and management?

Answer and explanation

Correct answer: B. Orbital cellulitis, treated with IV antibiotics after urgent imaging

  1. Step 1: Proptosis, painful and limited eye movement point to infection behind the orbital septum. Step 2. It threatens vision and can spread intracranially, so it requires admission, IV antibiotics and CT. Answer: Orbital cellulitis, treated with IV antibiotics after urgent imaging. Why not the others: Preseptal cellulitis lacks proptosis and ophthalmoplegia. Allergic eye disease has itch and no fever. A stye is a localised lid infection.
