Orbital cellulitis is an infective process involving ocular adnexal structures posterior to the orbital septum.1 It is an ocular emergency that not only threatens vision but also can lead to life-threatening complications such as cavernous sinus thrombosis, meningitis, and brain abscess. Visual loss ranges from 7.1% to 23.6%, which may be due to optic atrophy, central retinal artery occlusion, or exposure keratopathy with ulcer formation.2,3 Catastrophic local sequelae (infarction of optic nerve, sclera, choroid, retina) and intracranial spread (in sinus infections most common being frontal sinus, followed by ethmoid and maxillary sinuses) occur in untreated cases. The prognosis is good if prompt medical treatment is received.Abstract
