Orbital cellulitis (OC) is an infectious inflammation of orbital or periorbital tissues within the bony orbital cavity. Its ocular manifestations and symptoms include proptosis, erythema of eyelids, chemosis, visual acuity decline and diplopia, with or without systemic abnormalities such as fever and headache. Orbital cellulitis is a rare cause of exudative retinal detachment. Orbital cellulitis results from bacterial infection or non-bacterial infectious organisms including fungi and viruses in adjacent tissues including paranasal sinuses, eyelids, face, or distant locations through hematogenous extension. Prompt and appropriate antibiotic administration is the primary treatment for orbital cellulitis, although severe sight/life-threatening complications may still occasionally occur when antibiotics fail to clear up the infection.
A 16-year-old girl developed severe left orbital cellulitis in 4?days. Two exudative retinal detachment lesions were presented in her left eye retina. Blood cultures were performed which identified Staphylococcus aureus. However, the cause for the orbital cellulitis was not idenitfied in this patient. Systemic application of antibiotics together with topical antibiotics and corticosteroid was effective to the improvement of orbital cellulitis and resolution of exudative retinal detachment. The treatment of such clinical condition is that of orbital cellulitis in general. The exudative retinal detachment can resolve to a great extent upon cure of the underlying disease, followed by visual acuity recovery.
