Orbital cellulitis

Abstract

Orbital cellulitis is a significant infection that affects the ocular adnexal and associated orbital tissues. It is often a clinical diagnosis and can present as an ophthalmological emergency. The soft tissues posterior to the orbital septum are involved. Thus, the infection is deep and requires aggressive intervention compared with the more superficial infection of pre-septal cellulitis. Failure of prompt diagnosis and early treatment can lead to loss of vision and can be potentially life-threatening. The article discusses the clinical features, risk factors and management of orbital cellulitis. It provides an overview of the important differentials to consider and resultant complications that can occur.
