Vision Loss After Contact Lens-Related Pseudomonas Keratitis Bacterial keratitis caused by this Gram-negative organism is more fulminant and associated with a worse visual prognosis than that caused by most other common bacterial pathogens (1-3,7-9) Subjectively, the patient reports the sudden onset and rapid progression of ocular pain, redness, tearing, photophobia, and blurred vision

Atlas Entry - Varicella-zoster virus (VZV) epithelial keratitis Varicella-zoster virus (VZV) is a Herpes virus responsible for chicken pox and shingles With corneal epithelial involvement, the virus can cause punctate or dendritic epithelial keratitis The pseudodendrites caused by VZV can be differentiated clinically from "true" dendrites caused by Herpes simplex virus (HSV)
Atlas Entry - Herpes simplex virus (HSV) disciform keratitis Herpetic disciform keratitis is a primary endotheliitis resulting in both stromal and epithelial edema in a round (disciform) distribution with keratic precipitates underlying the area of edema The corneal edema and keratic precipitates appear to be out of proportion to the degree of anterior chamber inflammation, in contrast to uveitis with
