Abstract
To examine the widely accepted dogma that the eye is an immune-privileged organ that can suppress antigen immunogenicity, we explored systemic immune responses to a model vaccine antigen (tetanus toxoid) delivered to six compartments of the rodent eye (ocular surface, corneal stroma, anterior chamber, subconjunctival space, suprachoroidal space, vitreous body). We discovered that antigens delivered to corneal stroma induced enhanced, rather than suppressed, antigen-specific immune responses, which were 18- to 30-fold greater than conventional intramuscular injection and comparable to intramuscular vaccination with alum adjuvant. Systemic immune responses to antigen delivered to the other ocular compartments were much weaker. The enhanced systemic immune responses after intrastromal injection were related to a sequence of events involving the formation of an antigen "depot" in the avascular stroma, infiltration of antigen-presenting cells, up-regulation of MHC class II and costimulatory molecules CD80/CD86, and induction of lymphangiogenesis in the corneal stroma facilitating sustained presentation of antigen to the lymphatic system. These enhanced immune responses in corneal stroma suggest new approaches to medical interventions for ocular immune diseases and vaccination methods.

Abstract
Herpes simplex viruses (HSVs) can cause a variety of infections, including genital herpes. Despite effective antiviral therapy, HSV infections remain a significant worldwide public health problem. Vaccines offer the best hope for controlling spread and limiting HSV disease. This article discusses the pathogenesis and immunobiology of mucocutaneous HSV infections, summarizes the spectrum of diseases caused by HSV, and provides a review of the field of HSV vaccine research. This article also discusses what might be realistically expected of a vaccine intended for control of genital herpes and explores the question of whether a vaccine that is effective in controlling genital HSV disease might also be effective in controlling nongenital HSV disease. The efficacy of such vaccines for the full spectrum of HSV disease will eventually determine the timing and targeting of immunization, ranging from selective immunization in preadolescence to universal childhood immunization as part of the routine childhood regimen.

Abstract
Herpes stromal keratitis (HSK) is a blinding infectious disease that results from an array of immunopathogenic processes, including herpes simplex virus 1 (HSV-1)-specific T helper 1 (Th1) and Th2 cells, cytotoxic T cells and antibodies. As discussed here by Wayne Streilein and colleagues, strategies designed to prevent and treat this syndrome must be aware of the fact that the disease is multifactorial in its cause and pathogenesis.

Abstract
Herpes simplex virus (HSV) glycoproteins E and I (gE and gI) can act as a receptor for the Fc domain of immunoglobulin G (IgG). To examine the role of HSV IgG Fc receptor in viral pathogenesis, rabbits and mice were infected by the corneal route with HSV gE- or gI- mutants. Wild-type HSV-1 produced large dendritic lesions in the corneal epithelium and subsequent stromal disease leading to viral encephalitis, whereas gE- and gI- mutant viruses produced microscopic punctate or small dendritic lesions in the epithelium and no corneal disease or encephalitis. These differences were not related to the ability of the gE-gI oligomer to bind IgG because the differences were observed before the appearance of anti-HSV IgG and in mice, in which IgG binds to the Fc receptor poorly or not at all. Mutant viruses produced small plaques on monolayers of normal human fibroblasts and epithelial cells. Replication of gE- and gI- mutant viruses in human fibroblasts were normal, and the rates of entry of mutant and wild-type viruses into fibroblasts were similar; however, spread of gE- and gI- mutant viruses from cell to cell was significantly slower than that of wild-type HSV-1. In experiments in which fibroblast monolayers were infected with low multiplicities of virus and multiple rounds of infection occurred, the presence of neutralizing antibodies in the culture medium caused the yields of mutant viruses to drop dramatically, whereas there was a lesser effect on the production of wild-type HSV. It appears that cell-to-cell transmission of wild-type HSV-1 occurs by at least two mechanisms: (i) release of virus from cells and entry of extracellular virus into a neighboring cell and (ii) transfer of virus across cell junctions in a manner resistant to neutralizing antibodies. Our results suggest that gE- and gI- mutants are defective in the latter mechanism of spread, suggesting the possibility that the gE-gI complex facilitates virus transfer across cell junctions, a mode of spread which may predominate in some tissues. It is ironic that the gE-gI complex, usually considered an IgG Fc receptor, may, through its ability to mediate cell-to-cell spread, actually protect HSV from IgG in a manner different than previously thought.

Abstract
A majority of cases of preventable and/or curable ocular morbidity and blindness are caused by ocular infections. They may account for 70 to 90% of all ocular morbidity seen by family doctors, general practitioners, health centers, and local ophthalmologists in both developed and developing countries. Unfortunately, most health authorities and doctors, including ophthalmologists, consider these diseases to be of little or no importance because they are not fully aware of the high prevalence of these infections and the blinding sequelae which may occur following incorrect diagnosis and treatment. Also, they are not aware of the social and economic impact of these infections in the absence of proper management and implementation of preventive measures. In this review, we examine present knowledge of chlamydial and common viral ocular infections. We discuss the problems of diagnosis, management, and prevention and propose solutions relevant to developed and developing countries.

Abstract
A/J mice were immunized subcutaneously with ultraviolet light (UV) inactivated herpes simplex virus type-1, MP strain (HSV-MP). Control A/J mice were immunized subcutaneously either with media (unimmunized controls) or with live HSV-MP (immunized controls). Immunized and control mice were challenged ocularly with either MP or mP strain HSV-1 after corneal scarification and were followed for 3 weeks post corneal challenge. The mice were observed during this time period for signs of herpes simplex keratitis (HSK), lid lesions and encephalitis. At the time of sacrifice, the ipsilateral trigeminal ganglia were removed and assayed for latent HSV-1 using cocultivation on Vero cell monolayers. The results of these studies demonstrated that immunization with UV inactivated HSV (UV-HSV) gave the same protection against keratitis and encephalitis as immunization with live virus. Furthermore, the cocultivation assays indicated that immunization with either live HSV-1 or UV inactivated HSV-1 protected against the establishment of latency.

Abstract
Primary inoculation of mice and rabbits with an avirulent HSV-1 thymidine kinase negative (TK-) mutant reduced keratitis, mortality, and superinfection of the trigeminal ganglion (TG) as measured by cocultivation and iontophoresis-induced ocular shedding following ocular challenge with HSV-1 McKrae and W strains. However species differences were demonstrated; with complete protection in rabbits, and incomplete protection in mice. In mice, BUDR/autoradiography and restriction enzyme analysis identified both HSV-1 McKrae and W strains as having superinfected the TG, established latency and reactivated. Also, the avirulent TK negative inoculating strain was altered to a virulent TK positive strain through possible in vivo selection, mutation &/or host-modification, and possible in vivo recombination with the virulent challenge strains. We conclude that lower species differences require that potential HSV-1 vaccines be tested in non-human primates prior to clinical trials, and that a DNA-free subunit herpes vaccine represents a safer alternative to a live virus vaccine.

Abstract
The value of hyperimmune gammaglobulin (HGG) therapy in ulcerative herpetic keratitis was assessed in rabbits. HGG treated of early disease in normal rabbits was very effective, producing a 10-fold rise in the virus concentration needed to infect 50% of sites (CID50) and an 88% inhibition of ulceration after 2 days. The efficacy of the gammaglobulin preparations tested depended on their anti-HSV antibody content. Established disease was considerably less responsive to HGG therapy. No conclusive effect of HGG therapy could be demonstrated in rabbits with a previous HSV skin infection ('immunised'). Corticosteroid-induced geographic ulceration in immunised rabbits was not prevented by concurrent HGG therapy. The findings indicate that HGG is unlikely to represent a useful therapy for ulcerative herpetic keratitis but that it may be valuable in primary disease and in long-term prophylaxis.

Abstract
Since the great majority of patients possess immune response to herpes simplex virus (HSV), the influence of a topical anti-inflammatory corticosteroid (0.1% clobetasone butyrate) on ulcerative herpetic keratitis was studied in rabbits with a previous HSV skin infection (immunised) and compared with that in normal rabbits. Corticosteroid treatment had a much greater ulceration-exacerbating effect in immunised than in normal animals. On day 7 the mean area of ulceration in immunised rabbits were 3 times greater in treated eyes. 0.01% clobetasone butyrate treatment had less effect on immunised rabbits; 0.001% had no effect. It is concluded that the immunised rabbit provides a useful experimental model for studying the relationship between concentration of topical anti-inflammatory agents and enhancement of herpetic ulceration.

Abstract
The importance of specific immunity, especially cell-mediated, in resistance to herpes simplex disease is well documented, and animal experiments show that immune responses to previous herpetic infection can give considerable protection against reinfection in epithelial keratitis. Since susceptibility to stromal herpetic keratitis is probably determined in part by the extent of virus proliferation in the epithelium, immune responses to herpes simplex virus were studied in patients with epithelial or stromal keratitis, a group of patients with keratitis who were also severely atopic, and controls. The parameters measured were lymphocyte transformation, production of macrophage migration inhibition factor, and levels of serum antibody and immunoglobulin. No group differences were found except for a slight decrease in the whole blood culture assessment of lymphocyte transformation in stromal keratitis patients compared with seropositive controls and patients with epithelial disease. It is considered that in a small group of patients a deficiency in the specific cell-mediated immune response plays a role in determining the spread of virus into the corneal stroma.
