[Orbital infections].

Orbital cellulitis is a rare occurrence in ophthalmology practice. It is heterogeneous in terms of etiology, anatomical form and severity. Most often, it occurs adjacent to a sinus infection (frequently ethmoidal). Management must be systematized, adapted to the clinical examination and ancillary testing, and above all, proactive, since in certain situations, the functional and/or vital prognosis may be at stake. A clinical examination and urgent CT scan are essential for making the correct diagnosis, enabling us to assess the severity of the condition and determine whether surgery is required in addition to antibiotic therapy.
