Delayed resolution of eyelid swelling in preseptal cellulitis in a child: beware of causing occlusion amblyopia.

A 7-month-old child presented with a 6-day history of right eyelid swelling and redness. She was being treated with chloramphenicol ointment and oral flucloxacillin by the general practitioner. Clinical examination revealed features of preseptal cellulitis. There was no evidence of orbital involvement and the child was generally well otherwise. Her oral antibiotics were changed and she was adviced to attend for a review in 2 days time. However, the child did not return for a review. Three weeks later following resolution of the eyelid swelling, the child represented with a divergent squint in the right eye. Clinical and orthoptic investigations suggested occlusion amblyopia. The child is currently receiving patching treatment for the amblyopia and is awaiting surgery for squint eye.
