Microbial keratitis in children.

Forty-seven eyes with microbial keratitis occurring in 44 children under 16 years of age were studied. Under the age of three, 92% of the infections involved Pseudomonas aeruginosa and/or various streptococcal species; later in childhood the typical adult pattern of infection was more common. Overwhelming systemic infections, malignant disease with orbital involvement and congenital ocular adnexal disease were important predisposing factors in the infant years; trauma and acquired external eye disease became increasingly important in mid-childhood. Surgery was necessary in 28% of the eyes. Frequent tearing and lack of patient cooperation preclude reliance on topical antibiotic therapy alone. Despite the difficulties, the mainstay of management involves daily biomicroscopic evaluation and regular subconjunctival antibiotic injections. The logistical problems of achieving these aims are discussed.
