The authors characterized a murine model of herpes simplex virus (HSV) reactivation in which recurrent herpetic keratitis was obtained in up to 80% of animals. Five weeks after ganglionic latency was established in National Institutes of Health inbred mice after corneal inoculation, HSV type 1 (HSV-1) was reactivated by irradiating the previously inoculated eye with ultraviolet (UV) light. Comp...

A retrospective review of 68 consecutive episodes of microbial keratitis complicating 66 penetrating keratoplasties (PKs) showed major risk associations: suture-related problems (50%), contact lens wear (26%), previous herpes simplex infection (15%), graft failure (15%), and persistent epithelial defects (15%). Topical steroid (85%) and antibiotic (59%) usage were common iatrogenic factors. Hal...

Prostaglandin A2 (PGA2) inhibited the replication of herpes simplex virus type 1 in rabbit and human cornea stromal cells at concentrations of 1 to 5 microM while causing significant toxicity at 55 to 150 microM. Despite favorable therapeutic indices in cultured cells, PGA2 was not effective as a therapeutic agent in the treatment of herpetic keratitis in a rabbit model. The sequelae of disease...

Corticosteroids are being rn;;ed in different ophthalmic disorder as anti-inflamatory agent.  A.C.T.H. stimulated the supra renal glands and causes an increase steroid concentration of the blood. Corticosteroids can be used as anti­inflamatory agent locally ar.d systemically.  The new corticom,teroids like prednison, dex­xametason and prednisolon are more effective ( 5 to 10 times) than the o...

Herpes simplex keratitis (HSK) belongs to the major causes of visual morbidity worldwide and available methods of treatment remain unsatisfactory. Primary infection occurs usually early in life and is often asymptomatic. Chronic visual impairment and visual loss are caused by corneal scaring, thinning, and vascularization connected with recurrent HSV infections. The pathogenesis of herpetic ker...

herpes simplex virus (hsv) causes a wide range of pathologies in the human central nervous system (cns) such as stroke. it was proposed that there is an association between hsv infection and stroke with different results reported by the researchers using different methods. this study aimed to investigate the frequency of hsv among stroke patient and control groups. we detected hsv in 28 stroke ...
