Contact lens induced ulcerative keratitis is a serious complication which can be devastating for the patient if treatment is delayed. Extended wear is the commonest cause of microbial keratitis in contact lens wear. New extended wear silicone hydrogel contact lenses have higher oxygen transmissibility so that they can be worn continuously for 30 days. They can also be used as bandage contact le...

Purpose: To analyze epidemiological and microbiological aspects of microbial keratitis in children and adolescents. Methods: This retrospective cohort study was conducted at the Department of Ophthalmology and Visual Science, Escola Paulista de Medicina, Universidade Federal de São Paulo, between July 15, 1975, and December 31, 2010. We analyzed corneal samples from 859 patients with clinical...

Keratitis, inflammation of the cornea, can result in partial or total loss of vision and can result from infectious agents (e.g., microbes including bacteria, fungi, amebae, and viruses) or from noninfectious causes (e.g., eye trauma, chemical exposure, and ultraviolet exposure). Contact lens wear is the major risk factor for microbial keratitis; outbreaks of Fusarium and Acanthamoeba keratitis...

Experimental Acanthamoeba keratitis was induced in Wistar rats by intrastromal inoculation of Acanthamoeba polyphaga cysts. Keratitis developed in all corneas injected and was characterised by a diffuse granular opacity. The animals were examined for 70 days and a gradual reduction of keratitis was observed. Pathological sections showed liquefactive stromal necrosis and Acanthamoeba localised i...

OBJECTIVE To validate photographic bioimaging for evaluating the severity of herpes simplex virus keratitis. METHODS Stromal keratitis of patients in the Herpetic Eye Disease Study was clinically measured with a slitbeam micrometer and then photographed at trial entry. Calibrated images of 169 eyes were analyzed for the size, location, and density of stromal keratitis and endotheliitis, with ...
