Extension of preseptal cellulitis, particularly in young children in whom the orbital septum is not fully developed. This is a less common route of infection [1] . Direct inoculation of the orbit from trauma. Post-traumatic orbital cellulitis tends to develop within 72 hours of the injury. Post-surgery including orbital, lacrimal, strabismus and vitreoretinal surgery. Haematogenous spread from distant bacteraemia.
