Herpes simplex virus type 1 (HSV-1) can infect the cornea and achieve ganglionic latency. HSV-1 can later be activated by a variety of effectors although the exact mechanism of reactivation is unknown. Rabbits harboring latent HSV-1 strain McKrae can be induced to shed virus by ocular iontophoresis of epinephrine to the cornea. No studies have been done to investigate if corneal nerves are nece...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2013009702 DESCRIPTION A previously healthy 6-year-old male child presented in the emergency department with a 4-day history of painless erythematous-papulomacular rash that started on the left side of the forehead. The lesions became blistered and confluent, spreading to the nasal bridge...

BACKGROUND Long-term treatment with antiviral agents has been shown to prevent recurrences of genital and orofacial herpes simplex virus (HSV) disease, but it is uncertain whether prophylactic treatment can prevent recurrences of ocular HSV disease. METHODS We randomly assigned 703 immunocompetent patients who had had ocular HSV disease within the preceding year to receive 400 mg of acyclovir...

The clinical features of HIV/AIDS-related ocular manifestations in Korean patients were investigated in this study. Data on 200 consecutive Korean patients diagnosed with AIDS who visited the Seoul National University Hospital from January 2003 to June 2008 were reviewed. Fifty-seven patients (28.5%) had ocular manifestations, and they showed significantly lower CD4+ T cell count than patients ...

PURPOSE To assess the relative impact of elevated T-helper 2 (T(H)2)- and reduced T-Helper 1 (T(H)1)-dependent immune responses on ocular herpes simplex virus type 1 (HSV-1) infection. METHODS Signal transducer and activator of transcription protein 4 knockout mice (BALB/c-STAT4(-/-)) and wild-type BALB/c control mice were immunized with avirulent HSV-1 strain KOS or were mock-immunized. Thre...

We used a herpes simplex virus (HSV) type 1 ribonucleotide reductase (RR) null mutant (ICP6 delta) to study the role of HSV-1 RR in ocular HSV infections. We found that ICP6 delta was unable to induce vascularization of the cornea or stromal keratitis following inoculation into the cornea of BALB/c mice, but was able to induce a transient mild blepharitis. The parental strain (HSV-1 KOS) and a ...

UNLABELLED Acquired immune deficiency syndrome (AIDS) is associated with a wide spectrum of systemic and ocular infectious diseases. Little information is known about Herpes Simplex Virus type 1 (HSV-1) keratoconjunctivitis in association with AIDS. Because HSV-1 is becoming, day by day, a common eye disease (nearly 100% patients of over 60 years old harbor HSV in their trigeminal ganglia at au...

A mouse model for ocular reactivation of herpes simplex virus type 1 (HSV-1) was modified and used to study the effect of strain difference on the frequency of ocular HSV reactivation. Outbred male NIH white mice were immunized with 1.0 ml of anti-HSV serum with a neutralizing titer of 1:400 24 hr before infection and bilaterally infected at 10(5) plaque-forming units/eye with one of three HSV-...
