RESUMO
Although orbital abscess may originate from a number of sources, acute paranasal sinus disease is the most common source of infection. The clinical presentation is eyelid swelling, proptosis, conjunctival chemosis, diplopia, and decreased visual acuity. Diagnostic methods available for evaluating orbital abscess include sinus X-ray, ultrasound, computed tomography(CT), and bacterial culture of abscess content. Orbital abscess is treated with systemic antibiotics, or surgical draining followed by intravenous antibiotic therapy. Prompt diagnosis and treatment are necessary to prevent meningitis, subdural abscess, cavernous sinus thrombosis, frontal sinus thrombosis, visual loss from increased intraorbital pressure, even death. The authors exprienced a 2-month-old female neonate who presented with eyelid swelling, erythema, propotsis, eyeball deviation on right eye. Her orbital CT disclosed orbital abscess and only systemic intravenous antibiotics and topical antibiotic eyedrop instillation improved the symptoms.
