[Orbital cellulitis in children: Report of 60 cases]

The goal of this study was to describe the epidemiological, etiological, clinical and therapeutic features and clinical course of orbital cellulitis in children, and to assess the risk factors for retroseptal involvement.

This was a retrospective study including 60 children (67 eyes) diagnosed with orbital cellulitis. Two groups were defined according to the clinical form: pre- or retroseptal.

We studied 29 cases (34 eyes) of preseptal cellulitis and 31 cases (33 eyes) of retroseptal cellulitis. The mean age was 4 years. The male: female ratio was 1.3. The prescription of anti-inflammatory drugs and antibiotics prior to hospitalization was noted in respectively four and 10 patients. Eyelid edema was the principal sign (100% of cases); exophthalmia was noted in 19 eyes, ptosis in 27 eyes and chemosis in 10 eyes. Oculomotor disorders were present in 4 eyes. The mean C-reactive protein level was 53.15±27mg/l in preseptal cellulitis and 92.09±21mg/l in the retro-septal cases. Orbital computed tomography was performed in 31 patients and MRI in 5 patients. The pathway of entry of the orbital infection was primarily from the sinuses (23 cases). All of our patients had received broad spectrum intravenous antibiotic therapy. Three children had a cavernous sinus thrombosis and had been treated with anticoagulant therapy. Surgical drainage was performed in five patients. The course was favorable and without sequelae for all the patients. Two independent risk factors for retroseptal involvement were identified: the prescription of anti-inflammatory drugs prior to hospitalization, and sinus involvement.

Orbital cellulitis in children is a serious infection and requires close collaboration between the ophthalmologist, otolaryngologist, and pediatrician in order to be diagnosed and treated early so as to improve the prognosis for vision and life.
