Purpose To study: the epidemiology of an outbreak of adenoviral keratoconjunctivitis in a UK teaching hospital; disease presentation and its effect on clinical diagnostic efficiency; patterns of viral transmission between staff and patients; the effectiveness of infection control procedures in minimising outbreaks.Methods Prospective/retrospective clinical audit and retrospective audit of virological culture results: all viral culture swabs taken during an outbreak of adenoviral keratoconjunctivitis were analysed. The case records of patients whose viral swabs were positive for adenoviral culture were traced.

We recommend that all patients with a suspected diagnosis of post-SC should undergo CT scan (post-contrast orbits and post-contrast head, with multiplanar reformats and a careful review of the SOV and the cavernous sinus). Particular attention should be paid to exclude intracranial complications including subdural empyema and cerebral abscess. As soon as a diagnosis of post-SC is made, in addition to informing the referring clinical team, urgent opinion should be sought from ear, nose and throat (ENT), neurology and ophthalmology with a view to urgently drain of the paranasal sinuses`.

The diagnosis of pediatric orbital and periorbital conditions is addressed by a combination of a good clinical history, examination, fundoscopy and imaging. The main imaging modalities available are ultrasound, computed tomography and magnetic resonance imaging. This pictorial review focuses on the relative advantages of imaging methods in common pediatric orbital and periorbital pathology. Salient features of each condition will be discussed, providing key diagnostic signs to aid evaluation of children presenting with orbital symptoms and signs.
