Orbital cellulitis is an infection of the tissues around and behind the eye, most often arising from sinusitis (especially in children), sometimes from a skin or dental infection. The preseptal form (in front of the eyelid septum) is distinguished from the more serious orbital form (behind the eye).
The signs
A red, hot, very swollen eyelid, pain, fever. Warning signs — reduced vision, pain on eye movement, exophthalmos, double vision, feeling generally unwell — point to the orbital form.
A medical emergency
Orbital cellulitis requires an emergency consultation: antibiotics, most often with hospital admission for orbital forms, and a CT scan looking for an abscess and the causative sinusitis. Surgical drainage is sometimes necessary.
After the episode
Treating the entry point (sinusitis, dental focus, skin lesion) and close follow-up prevent recurrence.
Frequently asked questions
What is the difference between preseptal and orbital cellulitis?
The preseptal form stays in front of the septum: swollen eyelid but normal eye, preserved vision, painless movements. The orbital form involves the tissues behind the eye: it is the one that threatens vision and requires hospital admission.
