For the purpose of this symposium, the term "keratitis" implies suppurative nonviral and viral keratitis. Corneal ulcers have been described in ancient literature. But even today, despite the availability of a wide range of newer antimicrobials and new diagnostic techniques, infective keratitis continues to pose a diagnostic and therapeutic challenge. This article focuses on the key diagnostic clinical features of the most common organisms causing infective keratitis - bacteria, fungi, viruses, nocardia and acanthamoeba - in India. While the clinical features in some cases are fairly straightforward, most cases challenge the clinician. We describe the salient clinical features which can help arrive at a diagnosis to begin appropriate treatment immediately, prior to the laboratory report.
