Distinguishing infective versus noninfective keratitis.
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.
