In my position as pediatric ophthalmologist I see many young patients, often on an emergency basis. A few months ago, I received a call from the children hospital emergency room. A 2 week old baby was presented with copious purulent discharge from her eyes that started a few days before. Her parents were distraught and quite anxious with their first baby. I immediately made the diagnosis of ophthalmia neonatorum, but was perplexed as this much discharge is usually seen as a result of gonococcal infection, which starts shortly after birth. A quick look at Wills Eye Manual and Drug Guide powered by Skyscape on my PDA refreshed my memory and displayed the option of chlamydial infection. These two Skyscape produt's specified how to calculate the dosage of systemic antibiotic treatment, which saved me from trying to look for it on a computer or call one of the pediatricians in ER. The mother was then referred for tests to see if she harbored this infection. Indeed, Wills Eye Manual and Drug Guide let me reach a diagnosis and formulate a treatment quickly and easily. During the ensuing days I saw the baby improving dramatically to the relief of her parents.
