PURPOSE To report a case of peripheral ulcerative keratitis and necrotizing scleritis precipitated by trauma in a patient with mixed cryoglobulinemia due to hepatitis C viral infection. METHODS Case report and literature review. RESULTS A 62-year-old man with a history of mixed cryoglobulinemia developed an episode of necrotizing scleritis and peripheral ulcerative keratitis one month after...

Reactivation of herpes zoster ophthalmicus (HZO) can present as corneal involvement without any precedent neuralgia or characteristic herpetic rash. This form HZO be the first manifestation reactivation varicella virus and masquerade peripheral ulcerative keratitis. A 45-year-old male treated for necrotizing fasciitis (NF) one month back presented with painful diminution vision in right eye (RE...

PURPOSE Acanthamoeba keratitis usually presents as a necrotizing stromal inflammation. We report a rare presentation of granulomatous inflammation in Acanthamoeba keratitis METHODS Retrospective clinico-pathologic case series. RESULTS Five corneal tissues (3 corneal buttons, 2-eviscerated contents) from patients suffering from severe Acanthamoeba keratitis not responding to anti-Acanthamoeb...

Two cases of necrotizing keratitis following laser refractive corneal surgery, with stable and controlled Crohn's disease are described. A 40-year-old woman developed bilateral stromal inflammation and inferior thinning in the right eye along the flap edge within 1 day of uneventful bilateral IntraLase laser-assisted in situ keratomileusis. The other case is a 30-year-old man who also developed...

The inflammatory response to herpes simplex virus infection of the cornea was studied in athymic nude (nu/nu) and heterozygote (nu/+) BALB/c mice. Although athymic mice were highly susceptible to HSV infection and died 13 to 17 days after corneal inoculation, they failed to develop necrotizing keratitis of the cornea. Heterozygote mice survived the initial virual infection, but many of these mi...

PURPOSE Herpetic stromal keratitis (HSK) is a T-cell-mediated inflammatory disease initiated by a herpes simplex virus (HSV) infection of the cornea. Recently, studies in the HSK mouse model have shown that the immunopathogenic T cells are directed against the HSV protein UL6 cross-reacting with an unknown corneal autoantigen. Whether this type of autoimmunity plays a role in human HSK was anal...

We developed a murine model of ocular herpes simplex virus (HSV) disease which is particularly suited for testing stromal keratitis because most animals show some evidence of infection. Using this model, we characterized the ocular disease patterns caused by ten recent low-passage clinical isolates of HSV-1, as well as those caused by the established laboratory strains HSV-1 KOS and HSV-2 333. ...

Herpes simplex virus (HSV) keratitis is a common cause of ocular and visual morbidity. In this article, we systematically review published randomized clinical trials (RCTs) for HSV epithelial and stromal keratitis in order to establish a rational evidence-based foundation for treatment of these disorders. Articles for review were identified in the MEDLINE database from January 1, 1966, to May 3...

Multifocal stromal infiltrates or "satellite lesions" have been considered a characteristic feature of fungal keratitis. We examined two patients with nontuberculous mycobacterial keratitis who clinically presented with satellite lesions. The keratitis consisted of multifocal stromal infiltrates with indistinct white and fluffy margins. Both patients received topical fortified amikacin therapy ...

Stromal herpetic keratitis has a poor prognosis. To date, corticosteroids appear to be the most efficatious agents against the condition. However, corticosteroids are immuno6uppresive, and may cause recurrences. The recent findings of decreased cellular immunity in the condition offer the possibility of using levamisole as the therapeutic agent. The present investigation was undertaken to evalu...
