A 51-year-old woman presented with acute diplopia. Findings include right ptosis, a dilated, unreactive pupil, and impaired adduction and vertical ductions (figure 1). A skin lesion was noted on the right tip of the nose, residual from a vesicular rash over the right forehead 3 weeks earlier (figure 1). MRI demonstrated enhancement of the cisternal third nerve, obviating the need for angiograph...

Using nonsense and deletion mutants of herpes simplex virus type 1, we investigated the roles of three immediate-early proteins (ICP4, ICP27 and ICP0) in the establishment and reactivation of ganglionic latency in a mouse ocular model. DNA hybridization, superinfection-rescue, and cocultivation techniques provided quantitative data that distinguished between the failure of a virus to establish ...

Nearly 34 million people are currently living with HIV/AIDS: ocular complications are common, affecting 50% to 75% of all such patients at some point during the course of their illness. Cytomegalovirus retinitis is by far the most frequent cause of vision loss in patients with AIDS. Although the prevalence of cytomegalovirus retinitis is decreasing in industrialized countries because of the wid...

Infectious agents have been identified as a major cause of specific types of human cancers worldwide. Several microorganisms have been identified as potential aggravators of ocular adnexal neoplasms; however, given the rarity of these neoplasms, large epidemiological studies are difficult to coordinate. This study aimed to conduct an exhaustive search for pathogenic DNA in lymphoproliferative d...

herpes simplex virus type 1 establishes a latent infection in the peripheral nervous system following primary infection. during latent infection, virus genome exhibit limited transcription, with the hsv lats consistently detected in latency infected ganaglia. following ocular infection viral latency develops in the trigeminal ganglia. in this study pcr has been used for detection of hsv-1 nucli...

PURPOSE To calculate the incidence and prevalence of herpes simplex virus (HSV) eye disease in a large, well-defined population in Northern California, USA, and to determine the recurrence rate following an initial episode of disease in this cohort. METHODS A retrospective, observational, cohort study using population-based data and medical record review. The patient database of a large, regi...

PURPOSE The herpes simplex virus type 1 (HSV-1) U(S)1 gene encodes host-range and ocular virulence determinants. Mutations in U(S)1 affecting virulence are known in strain OD4, but the genomic variation across several strains is not known. The goal was to determine the degree of sequence variation in the gene from several ocular HSV isolates. METHODS The U(S)1 gene from six ocular HSV-1 isola...

background and aims: herpes simplex virus (hsv) is a common cause of corneal disease and is the leading infectious cause of corneal blindness among developed nations. this study is aimed to provide an estimation of the incidence of herpes simplex virustype-1, 2(hsv1, 2) and varicella zoster virus (vzv) in tears and swab from eye infection by polymerase chain reaction (pcr) in eye disease in a s...

PURPOSE To elucidate the manifestations of ocular injuries in the colored corn starch dust explosion at a Taiwan water park. METHODS This is a retrospective, non-comparative, consecutive-interventional case series. Fifty explosion-injury patients on 27 June 2015 treated at Chang-Gung Memorial Hospital, Linkou, were included. Thorough ophthalmic examinations were based on emergent triage and c...
