Bacterial keratitis is an opportunistic infection of the avascular corneal stroma, initiated by a breakdown of the epithelial barrier. Corneal abrasion with infected material, extended-wear contact lenses, eyelid disease, and disorders of the ocular surface are predominant contributing factors. Acute bacterial conjunctivitis occurs when sufficient bacteria are introduced into the fornices to overwhelm normal bacteriostatic and flushing mechanisms. Chronic conjunctivitis is associated with a constant adnexal source of bacteria and resolves when the source is successfully treated. Rapid diagnosis and treatment of bacterial keratitis are essential to limit stromal scarring and minimize visual loss.

Idiopathic facial aseptic granuloma (IFAG) is a disorder that usually occurs during early childhood. Its pathogenesis remains poorly understood. The objective of this study was to investigate possible relationships between IFAG and childhood rosacea. This was a retrospective multicenter study of patients attending four French dermatologic centers diagnosed with IFAG between October 2000 and July 2007. Patients and their parents were asked to come for a follow-up visit or to make an appointment for a telephone interview. Clinical symptoms of childhood rosacea were recorded: flushing, permanent or recurrent erythema; facial telangiectasia; papules and pustules on the face without comedones or microcysts; preferential location of the lesions on the convexity of the face; and ophthalmologic involvement of rosacea (recurrent chalazions, conjunctival hyperemia, keratitis). Thirty-eight patients, 20 girls and 18 boys, were included in the study. The median age at the time of diagnosis of IFAG was 43 months, with a median follow-up of 3.9 years. Sixteen patients (42.1%) had at least two criteria of childhood rosacea, 11 of 32 (34.4%) with a single lesion and 5 of 6 (83.3%) with multiple lesions. Children with IFAG are at risk for childhood rosacea, and follow-up is advised, including periodic ophthalmologic assessment.
