Herpes simplex virus-1 (HSV-1) infects the majority of the world’s population during their lifetime. The prevalence of HSV primarily depends on geographic location, socioeconomic status, and age. HSV ocular disease rarely manifests as primary disease and most commonly as a recurrent disease. Recurrent HSV affects all the anterior segment structures in various clinical forms. In the cornea, HSV ...

Herpes simplex virus type I (KOS) was instilled onto the eyes of rabbits with experimentally induced xerophthalmia (vitamin A deficient) and control animals fed a vitamin A supplemented diet. The severity of the herpes virus-induced corneal disease, assessed by biomicroscopic examination and by counting the number of corneal lesions as well as by determining the virus titers, was significantly ...

BACKGROUND Herpes uveitis has been previously reported to present with hyphema, but hemorrhagic hypopyon is rarely reported as a herpetic uveitis manifestation. We report a case of herpes simplex virus (HSV) presenting with hemorrhagic hypopyon, and speculate on the underlying pathophysiology with relation to an intravascular lymphoma which was subsequently diagnosed as a result. CASE PRESENT...

Ocular herpes simplex virus (HSV) infection remains a major cause of corneal blindness. Several topical and oral antiviral medications have been used to treat herpetic keratitis. Advances in topical ophthalmic antivirals have been made over the past several decades. The first antivirals that were discovered were cytotoxic, while the antivirals developed more recently, such as acyclovir and ganc...

Introduction Herpes Simplex keratitis (HSK), caused by Herpes Simplex Virus type 1 (HSV-1), is the leading cause of infectious corneal blindness in the western world [1]. Initial infection develops through ocular surface entry from droplet spread [2]. Once HSV-1 has breached the epithelial barrier of the ocular surface, it is recognized by Toll-Like Receptors (TLRs), which then activate the app...

The induction of the interferon mechanism in rabbit corneal, conjunctival, iris, and kidney tissue cultures with polyinosinic-polycytidylic acid complex protects against infections with herpes simplex virus. The degree of protection is inversely proportional to the viral challenge dose and is significantly enhanced by the addition of neomycin. The potential application of these observations to ...

Human Herpes Virus (HHV) is a DNA virus and is the most important viral pathogen causing intraocular inflammation. HHV is classified into types 1-8. Among these types, HHV-1, HHV-2, HHV-3 Varicella Zoster Virus (VZV) and HHV-5 Cytomegalovirus (CMV) are known to cause herpetic viral retinitis, including acute retinal necrosis and CMV retinitis. Herpes viral retinitis can be diagnosed from charac...

PURPOSE To report the diagnosis, management, and outcome of acute retinal necrosis syndrome in children. METHOD Case series of three consecutive children aged 11 years and younger who were diagnosed with acute retinal necrosis. In addition to full ocular and systemic examinations, the children underwent vitreous biopsy (Patients 1 and 2) or aqueous tap (Patient 3) for polymerase chain reactio...
