Periorbital and orbital cellulitis in children

Area of Science:

• Ophthalmology
• Pediatrics
• Infectious Diseases

Background:

• Orbital and periorbital cellulitis are common infections affecting the eye socket and surrounding tissues.
• Understanding distinct clinical presentations and causative pathogens is crucial for effective management.
• Distinguishing between preseptal and orbital cellulitis impacts treatment strategies and prognosis.

Purpose of the Study:

• To analyze clinical and laboratory data of 87 orbital and periorbital cellulitis cases.
• To identify distinct clinical presentations and associated pathogens.
• To review pathophysiology and formulate a management approach.

Main Methods:

• Retrospective review of 87 patient cases with orbital and periorbital cellulitis.
• Analysis of clinical data, including history of trauma and infection focus.
• Laboratory investigations included blood cultures and pathogen identification from exudates.

Main Results:

• Two distinct groups emerged: 45 patients without trauma/focus (34% positive blood cultures, 82% Haemophilus influenzae) and 42 with adjacent infection (1 positive blood culture, Staphylococcus aureus/Streptococcus common).
• Thirteen patients had orbital cellulitis, presenting with older age and higher incidence of sinus disease.
• Haemophilus influenzae was a predominant pathogen in cases without a clear infectious source.

Conclusions:

• Clinical presentation and etiology of orbital and periorbital cellulitis vary significantly.
• Prompt identification of causative agents guides appropriate antibiotic therapy.
• Orbital cellulitis in older patients may be linked to underlying sinus pathology.
