Infectious crystalline keratopathy: management of three cases with different risk factors

We present the management of three cases of infectious crystalline keratopathy. The first one, in a 46-year-old patient with two previous penetrating keratoplasties; the second one, in a 46-year-old patient with chronic alcoholism and limbal insufficiency; and the third one, in a 70-year-old patient with bullous keratopathy. Other systemic conditions that may mimic infectious crystalline keratopathy, such as multiple myeloma, gout or cystinosis were ruled out on each patient by laboratory testing. The cases were managed with topical or topical and systemic treatment that led to the disappearance of the symptoms. Infectious crystalline keratopathy is a chronic and indolent pathology in which interlamellar bacterial plaques are observed in absence of apparent ocular inflammatory signs. Microorganisms penetrate the cornea through epithelial defects, commonly after a penetrating keratoplasty, although other risk factors may be present.
