Abstract
A 40-year-old Asian Indian woman, diagnosed as having idiopathic panuveitis (elsewhere) 3 years earlier and being treated with oral steroids (20 mg/day) and methotrexate (25 mg/week), presented to us with worsening vision in both eyes. Her best corrected visual acuity (BCVA) was perception of light in her right eye and counting fingers close to face in her left eye. A slit lamp examination showed an anterior chamber (AC) reaction (1+) in both eyes with posterior synechia, a total cataract in her right eye, and pseudophakia in her left eye. The left fundus showed vitritis, vitreous membranes, chorioretinitis, multifocal areas of retinitis, and retinal vascular sheathing. A systemic examination showed extensive multifocal areas of tinea corporis on the hands and torso. Owing to the leukocytosis (22,000 cells/mm3), diagnostic vitrectomy was initially deferred and 100 mg of oral itraconazole was given twice a day for 3 months. The vitritis improved a little and her total white blood cell (WBC) count improved with treatment of the skin infection. Following a diagnostic vitrectomy later in her left eye, resolving areas of retinitis were seen. Complete resolution of eye inflammation was seen at the end of 6 weeks. At the 6-month follow-up, her BCVA was 6/18 in left eye and she was off oral steroids and methotrexate, with no recurrence of inflammation. We speculate a probable association between the ocular inflammation and extensive tinea corporis based on the therapeutic response to itraconazole.

Abstract
The causes of posterior uveitis can be divided into infectious, autoimmune, or masquerade syndromes. Viral infections, a significant cause of sight-threatening ocular diseases in the posterior segment, include human herpesviruses, measles, rubella, and arboviruses such as dengue, West Nile, and chikungunya virus. Viral posterior uveitis may occur as an isolated ocular disease in congenital or acquired infections or as part of a systemic viral illness. Many viruses remain latent in the infected host with a risk of reactivation that depends on various factors, including virulence and host immunity, age, and comorbidities. Although some viral illnesses are self-limiting and have a good visual prognosis, others, such as cytomegalovirus retinitis or acute retinal necrosis, may result in serious complications and profound vision loss. Since some of these infections may respond well to antiviral therapy, it is important to work up all cases of posterior uveitis to rule out an infectious etiology. We review the clinical features, diagnostic tools, treatment regimens, and long-term outcomes for each of these viral posterior uveitides.

Abstract
PURPOSE To describe a patient with sudden unilateral loss of vision associated with white inner retinal lesions and a history of a nonspecific viral infection. METHODS Case report. We reviewed the medical record and retinal angiogram of one patient. RESULTS The patient presented with a sudden loss of visual acuity in the left eye. Fundus examination revealed multiple white inner retinal lesions and hyperemic optic disks in both eyes. Spontaneous improvement of visual acuity and resolution of the retinal lesions were noted over the ensuing weeks. CONCLUSION Retinitis can present as a nonspecific response to various infectious agents. We herein report a case of acute multifocal inner retinitis associated with a nonspecific viral illness.

Abstract
Herpetic eye disease is common and is frequently associated with intraocular inflammation or uveitis. Despite recent advances in measuring anti-herpes virus antibodies and viral DNA in ocular fluids, diagnosis remains largely clinical. The two more common syndromes include anterior uveitis, often associated with keratitis, and the acute retinal necrosis (ARN) syndrome. Treatment is complex and requires careful monitoring to provide the appropriate balance of antiviral medication and corticosteroids. Long-term prophylaxis with oral antiviral agents may be required in selected patients to help prevent the vision-compromising complications associated with recurrences.

Abstract
UNLABELLED Ninety men and women with recurrent genital HSV type 2 participated in a randomized, single-blind, masked investigator, controlled multi-centre study comparing the efficacy of ointment of Canadian propolis containing natural flavonoids with ointments of acyclovir and placebo (vehicle) on healing ability and capacity to remedy symptoms. Thirty individuals were randomized to each group. Treatment was intended to start in the blister phase. All participants had HSV type 2 isolated, confirmed by serum immunoglobulin levels. The participants were examined on the 3rd, 7th and 10th days of treatment by gynaecologists, dermatovenerologists or urologists at seven different medical centres. Apart from clinical symptoms the number and size of the herpetic lesions were noted. At each examination the lesions were classified into four stages: vesicular, ulcerated, crusted and healed. The study ointments were applied to affected areas four times daily. In women with vaginal or cervical lesions a tampon with the appropriate ointment was inserted four times daily for 10 days. Endpoint variables were healing time and time until loss of symptoms. RESULTS On Day 10, 24 out of 30 individuals in the propolis group had healed. In the acyclovir group 14 out of 30 and in the placebo group 12 out of 30 had healed. (p = 0.0015). The healing process appeared to be faster in the propolis group. In the propolis group 15 individuals had crusted lesions on Day 3 compared to 8 individuals in the acyclovir group and none in the placebo group (p = 0.0006). On Day 7, 10 participants in the propolis group, 4 in the acyclovir group and 3 in the placebo group had healed. At the initial examination all patients had local symptoms and 28% general symptoms. At Day 3, 3 patients in the propolis group had local symptoms compared to 8 and 9 in the acyclovir and placebo groups respectively. Of the women, 66% had vaginal superinfections of microbial pathogens at the initial examination. In the acyclovir and placebo groups no change in the vaginal flora was found following treatment whereas in the propolis group the incidence of superinfection was reduced by 55%. (p = 0.10 n.s.). CONCLUSION An ointment containing flavonoids appeared to be more effective than both acyclovir and placebo ointments in healing genital herpetic lesions, and in reducing local symptoms.

Abstract
PURPOSE To describe a case of retinal perivasculitis in an immunocompetent patient with systemic herpes simplex infection. METHODS Polymerase chain reaction amplifications were performed for aqueous and blood samples using primers specific for the following members of the herpesvirus family: cytomegalovirus, Epstein-Barr virus, herpes simplex virus (types 1 and 2), and varicella-zoster virus. The patient was placed on intravenous acyclovir and systemic corticosteroids. RESULTS A positive polymerase chain reaction signal was found only for herpes simplex virus type 1. Vision in the left eye improved from light perception to 20/25, and signs of retinal perivasculitis resolved. CONCLUSION The use of molecular diagnostic modalities in clinical practice may aid in determining infectious etiologies in patients with atypical clinical manifestations.

Abstract
BACKGROUND Different viruses have been reported to be involved in retinal diseases in animal systems. In humans, herpes simplex virus and cytomegalovirus have been found to cause retinal disease. Most of the studied viruses are neurotropic. In this study, the in vitro susceptibility of human retinal pigment epithelial cells (RPEC) to representative members of different groups of human pathogenic viruses was investigated. METHODS Early cultures of RPE C - after two or three passages - were infected with the following viruses: herpes simplex virus (HSV) type 1, human herpesvirus 6 (HHV-6), Epstein-Barr virus (EBV), cytomegalovirus (CMV), adenovirus types 1 and 7, measles virus, parainfluenza virus and coxsackie virus B3. RESULTS Cultures of RPE C could be infected with neurotropic viruses like HSV or measles virus as well as with typical respiratory viruses like parainfluenza or adenoviruses. Coxsackievirus, an enterovirus, replicated as well as human CMV, whereas EBV and HHV-6, two lymphotropic viruses, failed to infect RPE. CONCLUSION These findings suggest that a variety of viruses, including those causing rather common illnesses, might be capable of inducing retinal lesions under certain circumstances due to haematogenous spread during the course of viraemia.

Abstract
We applied the technique of DNA amplification with the polymerase chain reaction to nine aqueous humor and five vitreous samples from HIV-1-infected patients with clinically diagnosed cytomegalovirus retinitis. For the amplification, recently published primers specific for herpes simplex virus (HSV), varicella zoster virus (VZV) and cytomegalovirus (CMV-1) were used. Additionally, a newly developed primer pair specific for the main immediately early gene of CMV (CMV-2) was selected and compared with the published one. All primers were tested on noninfected and HSV-, VZV- and CMV-infected human fibroblast cell culture supernatant, thereby excluding cross-reactivity of the chosen primers. In none of 13 aqueous humor and six vitreous samples of healthy controls was any viral DNA amplified. Using the CMV-1 primers, we detected CMV DNA in five of nine aqueous humor and three of five vitreous samples amplifying a DNA fragment 435 base pairs in length. With the CMV-2 primers, we detected a CMV DNA fragment with a length of 110 base pairs in eight of nine aqueous humor and in four of five vitreous samples. Additionally, CMV DNA was found in three of nine urine and two of nine saliva specimens. Both CMV and HSV DNA were amplified in one aqueous sample. Varicella DNA was not detected in any of the specimens. Thus, the polymerase chain reaction is more sensitive than other comparable diagnostic tests and may provide an alternative to conventional virus isolation and in situ hybridization techniques for the laboratory diagnosis of viral ocular disease.

Abstract
BACKGROUND The ideal management of intraocular inflammation may require a tissue diagnosis. Diagnostic vitrectomy is a well-established method for acquiring such tissue. However, in some patients, the diagnostic pathology is limited to the choroid and retina and vitrectomy may yield no useful information. In such cases, a more aggressive surgical approach to obtain tissue may be useful. METHODS The authors performed chorioretinal biopsies on seven patients with progressive chorioretinal lesions of unknown etiology. Indications for biopsy included: (1) macular-threatening lesions unresponsive to therapy, (2) suspicion of malignancy, or (3) suspicion of an infectious etiology. In all cases, it was expected that the results would alter therapy or other aspects of clinical care. Preoperative visual acuity was 20/200 or worse in each eye biopsied with one or more peripheral chorioretinal lesions present. Biopsy specimens were divided into three parts and submitted for light and electron microscopy, immunohistochemistry, and tissue culture. RESULTS On the basis of the biopsy findings, a diagnosis of multifocal choroiditis and subretinal fibrosis was rendered in three eyes, sarcoidosis in two eyes, and viral retinitis in two eyes. Therapy was changed in five patients. Final visual acuity was unchanged or improved in five eyes. Complications included the progression of lens opacity in all eyes and the development of phthisis in one eye that was extensively diseased preoperatively. CONCLUSION Chorioretinal biopsy may provide useful information for determining the diagnosis and guiding the subsequent management of patients with progressive chorioretinal lesions of unknown etiology.

Abstract
Viruses are one of the most common causes of infections involving the posterior segment of the eye. Such infections can occur either on a congenital or an acquired basis, and may affect primarily the retina or the choroid. Congenital cytomegalovirus (CMV) and rubella infections may result in retinitis. CMV retinitis is also the most common cause of acquired viral retinitis, primarily because of the acquired immunodeficiency syndrome (AIDS). Other types of viral retinitis, such as those caused by herpes simplex or herpes zoster, can occur in immunocompromised or immunocompetent individuals. Retinitis or choroiditis caused by viruses such as measles, influenza, Epstein-Barr virus, and Rift Valley fever virus, typically occurs subsequent to an acute viral systemic illness. The systemic and ocular manifestations, as well as the histopathology, laboratory tests, differential diagnoses, and treatment regimens for each of the individual viruses are discussed in detail.

Abstract
Over the past two decades, the recognition of viral enzymes and proteins that can serve as molecular targets of drugs has revolutionized the treatment of viral infections. Beginning with acyclovir, a number of systemically administered agents which are both relatively safe and effective for the treatment of herpetic infections and human immunodeficiency virus (HIV) infections have become widely available. Because of increased numbers of herpes virus infections, as well as the rising epidemic of HIV infections, the ophthalmologist is, more likely than ever before to be involved in the treatment of severe and frequent ocular infections caused by herpes viruses. In addition, the acute retinal necrosis (ARN) syndrome has been demonstrated to be caused by herpes viruses and a once rare retinal infection caused by cytomegalovirus is common in patients with the acquired immunodeficiency syndrome (AIDS). In this article, four systemic antiviral drugs (Vidarabine, Acyclovir, Ganciclovir, and Foscarnet) that have demonstrated usefulness in the treatment of ophthalmic disease are reviewed in detail with regard to their mechanisms, applications, effectiveness, and side effects.

Abstract
Two patients who had similar clinical presentations of bilateral multiple chorioretinal lesions and needed a correct diagnosis underwent chorioretinal biopsy. The biopsy from one patient demonstrated mainly a B cell infiltrate in choroidal and subretinal nodules, while the biopsy from the second patient showed mainly macrophages in the retina. These findings directed the therapeutic approach taken in each patient. Although chorioretinal biopsy is an invasive procedure with the potential for serious complications, the resultant finding may aid in the diagnosis and guide the subsequent management of certain patients presenting with serious ocular findings of undefined etiology.

Abstract
Two patients developed acute changes in vision two to four weeks after a febrile illness. On ophthalmic examination, each patient had bilateral vitreitis without anterior segment inflammation and multiple, bilateral, round, yellow-white inner retinal lesions that were located in the posterior pole and midperiphery. Laboratory tests did not contribute to a diagnosis. Symptomatic visual loss was caused by neuroretinitis and serous retinal detachment in one patient and by an occluded branch retinal artery in the other. The multifocal retinal lesions resolved gradually without treatment over several months with minimal or no residual retinal changes. Acute multifocal inner retinal lesions may be associated with a preceding nonspecific viral illness and may cause a sudden change in vision if associated with neuroretinitis, serous retinal detachment, or retinal vessel occlusion. We have termed this constellation of ophthalmic findings acute multifocal inner retinitis.

Abstract
The acute retinal necrosis (ARN) syndrome represents a specific pattern of clinical presentation for certain herpes virus infections in the posterior segment of the eye. The classically described triad of the ARN syndrome consists of (1) an arteritis and phlebitis of the retinal and choroidal vasculature, (2) a confluent, necrotizing retinitis that preferentially affects the peripheral retina, and (3) a moderate to severe vitritis. Anterior segment inflammation, optic neuritis, and late retinal detachment are also common features of this disorder. Definitive evidence now implicates at least two members of the herpes virus family; varicella zoster virus and herpes simplex virus as causative agents. This paper summarizes the clinical presentation, as well as the currently recommended treatment regimen for the ARN syndrome, highlighting recent advances that have resulted in a significant improvement in the visual prognosis for affected patients.

Abstract
Following uniocular anterior chamber injection of HSV-1 (KOS) in BALB/c and A/J mice, it is paradoxical that (a) acute retinal necrosis (ARN) develops only in the uninjected eyes, and (b) ARN occurs only in mice that are immunocompetent, event though these mice invariably display anterior chamber associated immune deviation (ACAID), wherein delayed hypersensitivity to HSV antigens is grossly impaired. Previous studies have revealed that ARN develops only if the titer of infectious virus in the contralateral eye exceeds 4 Log10 PFU, indicating that virus infection is essential to ARN. However, HSV-1 titers in contralateral eyes of similarly infected athymic mice also exceed 4 Log10 PFU, even though these mice never develop ARN - implying that virus alone is insufficient to cause retinal cell destruction. In an effort to define the pathogenic immune component of ARN, we have evaluated in vitro viral antigen-specific T cell responses in mice with ARN and ACAID. We found that T cells, harvested from draining ipsilateral cervical lymph nodes and contrateral eye proliferate in response to viral antigens, express IL-2 receptors, and include HSV-1-specific precursor cytotoxic T cells (pTc), but not direct cytotoxic T cells (Tc). Since the time of appearance of HSV-specific pTc in the contralateral eye coincides with entry of infectious virus into that eye, and since their mutual appearance heralds the onset of retinal necrosis, we conclude that destruction of the retina is initiated by virus-specific cytotoxic T cells that lyse HSV-infected retinal cells.

Abstract
A systemically healthy 22-year-old man presented with unilateral acute retinal necrosis (ARN) that featured diffuse retinal whitening throughout the posterior retina, exudative retinal detachment, and a visual acuity of no light perception. Diagnostic vitrectomy revealed necrotic retinal cells containing intranuclear inclusions visible with light microscopy. On electron microscopy, viral particles consistent with a herpes family virus were detected. Culture of the vitrectomy specimen showed herpes simplex, type 1 (HSV 1) and rising convalescent serum ELISA titers to HSV 1 confirmed a recent infection. This case of ARN is unusual for its severity, early macular involvement, and development of exudative retinal detachment. In addition, it represents one of the few reported cases in which HSV 1 has been confirmed by both vitreous culture and serum titers as the etiologic agent. A review of the literature suggests that posterior segment inflammatory conditions secondary to HSV 1 can be associated with exudative retinal detachment, a clinical finding that may help differentiate such conditions from other infectious causes of chorioretinitis.

Abstract
7 cases of multifocal choroiditis and panuveitis are reported here (6 females, 1 male). All clinical data were carefully considered. In all cases an aqueous sampling was made for the detection of anti-herpes virus antibodies in aqueous and serum. 3 specificities were tested: herpes simplex (HSV), herpes zoster (HVZ) and cytomegalovirus (CMV). An intraocular synthesis of specific antibodies was found against VZV in 2 cases and against HSV in 1 case. There was another presumptive case for HSV.

In order to determine whether antiviral immunity is pathogenic in mouse eyes, HSV-1 was injected into the anterior chamber of one eye of adult athymic BALB/c mice. The eyes of these T cell deficient mice were examined clinically and histopathologically for ocular disease. The anterior segment of injected eyes developed progressive inflammatory reactions that eventually destroyed the ciliary body and then progressed to the posterior compartment where partial necrosis occurred, but only in the inner layers of the retina. A milder form of the same process developed between 7 and 10 days in the contralateral eye. Uninoculated eyes displayed little evidence of choroiditis, hemorrhage, massive necrosis, or disintegration of the architecture of the retina. Since these are features that are found in contralateral retinas of euthymic BALB/c mice infected in one eye via the anterior chamber route, it is concluded that acute retinitis found in contralateral eyes of immunocompetent mice has an immunopathogenic basis. However since euthymic mice develop anterior chamber associated immune deviation (ACAID) (and therefore do not display virus-specific delayed hypersensitivity), the identity of the relevant immune effector remains unknown. Based on these observations and our previous ocular findings following intracameral inoculation of HSV-2, we suggest that in susceptible mice, herpes simplex viruses can induce several pathogenetically distinct forms of retinitis, some of which are mediated by virus-specific immune effector cells.

Abstract
The authors have isolated herpes simplex virus type 1 (HSV-1) from the vitreous of two patients with acute retinal necrosis. Clinical and laboratory data suggest that one case represented a primary HSV-1 infection, whereas the other case appeared to be a recurrent HSV-1 infection. In the primary case, changes on magnetic resonance imaging (MRI) suggest spread of the virus posteriorly to both optic tracts and the lateral geniculate ganglia. This case shares many features with the "von Szily" experimental model for HSV retinitis in the mouse.

Abstract
Ocular pathology in the first European case of human bat-borne rabies is described. The patient was a 30-year-old bat scientist who seven weeks after bat bite developed neurological symptoms and died 23 days later. Rabies virus antigens were detected in brain smears. After extensive virological studies the virus turned out to be a rabies-related virus, closely resembling the Duvenhage virus isolated from bats in South Africa in 1980. By light microscopy focal chronic inflammatory infiltration of the ciliary body and of the choroid was found. PAS-positive exudate was seen in the subretinal and in the outer plexiform layers of the retina, and retinal veins showed endothelial damage and perivascular inflammation. Many of the retinal ganglion cells were destroyed. The presence of rabies-related viral antigen in the retinal ganglion cells was shown by positive cytoplasmic immunofluorescence, though electron microscopy failed to identify definite viral structures in the retina. By immunohistochemistry glial fibrillary acidic protein was observed in the Müller's cells, which are normally negative for this antigen but express it as a reactive change when the retina is damaged. Synaptophysin, a constituent of presynaptic vesicles of normal retinal neurons, was not detected in the retina.

Abstract
The authors present a series of seven patients with acute visual loss associated with mild anterior uveitis, multifocal retinal vasculitis, retinal capillary nonperfusion, retinal hemorrhage, disc swelling, and vitreitis. Oral prednisone was of some benefit in these patients and oral acyclovir was generally ineffective. Neovascular complications including retinal, disc, choroidal, and iris new vessels were common, requiring photocoagulation in five patients. Horseshoe tears developed in two patients in zones of uninvolved retina but retinal detachment did not occur. The etiology remains unknown, although it may represent either a localized ocular form of Behçet's disease or other systemic syndrome, infection with a herpes group virus other than zoster varicella virus, or a manifestation of an undefined infectious agent.

Abstract
Ocular herpes simplex disease has a variable pattern of manifestations and recurrences as a result of the site and extent of the infection, the host immunologic events, the trophic damage within ocular tissues, and the toxic effects of antiviral medications. Laboratory research has established a clinical model and a working hypothesis about the complex pathophysiologic features of the disease and the interaction of the virus with its host tissue. Recent studies have further defined the viral genome and its role in virulence and pathogenicity. Antiviral therapy is effective in some but not all aspects of the ocular infection. A proposed clinical classification of ocular herpes simplex is based on the manifestations associated with viral disease and those associated with the host response and the subsequent structural damage. A plan for medical and surgical management of ocular herpes simplex, based on current knowledge of the disease process, relates to the integrity of the epithelium and the presence of active viral disease.

Abstract
Acyclovir, an oral antiviral agent that inhibits viral DNA replication, was used to treat 27 patients (16 males, 11 females) (mean age, 50 years) with vision-threatening herpes simplex virus (HSV) infections. Twenty patients had active stromal keratitis or keratouveitis, four had controlled nonnecrotizing stromal keratitis but could not taper topical medications, and four eczema patients with previous HSV infections had intraocular surgery (1 of these patients also is included in the 20 with active stromal keratitis). All 20 patients with active stromal keratitis or keratouveitis improved on acyclovir, all four patients using acyclovir postoperatively were disease-free while on the drug, but only two of the four patients using acyclovir to assist tapering topical medications were successful. There has been only one recurrence during a cumulative 194 months while on acyclovir. Thirteen patients have remained on acyclovir, and three who stopped acyclovir had prompt recurrences. Acyclovir seems to be a promising adjunct antiviral agent for the treatment of recalcitrant epithelial, stromal, or uveal disease secondary to HSV.

Abstract
Uveitis may be the first presentation of a wide variety of underlying ocular and systemic diseases. It is important for the ophthalmologist to make a specific diagnosis in order to instigate specific therapy and give an accurate prognosis. The ability to recognise the clinical patterns of uveitis and to initiate appropriate investigations should form the basis of the ophthalmologist's management of the condition. To this end, we have considered uveitis under four major patterns of presentation--anterior uveitis, intermediate uveitis, posterior uveitis, and panuveitis--with subclasses within each of these four groups. We have outlined both the investigations which facilitate diagnosis of the possible underlying causes of inflammation and the interpretation of the results of such investigations.

Abstract
Acyclovir has been widely used against the various manifestations of eye disease due to herpes simplex since it first became generally available in the UK nearly five years ago. This paper discusses the rational indications for its use, through considerations of its pharmacology and pharmacokinetics, and through results of the many clinical trials that have been carried out to investigate its effects since its clinical efficacy was first demonstrated in 1979.

Abstract
A chorioretinal biopsy was obtained from a patient with subretinal fibrosis and chronic uveitis. The biopsy specimen was analyzed by conventional light and electron microscopy and by immunohistochemical methods. These demonstrated a markedly inflamed choroid with a predominance of B cells and plasma cells. Complement and IgG were deposited above Bruch's membrane. The subretinal fibrosis tissue contained islands of cells with retinal pigment epithelial characteristics; however, some of these cells demonstrated surface determinants of Müller cells. There were no circulating antiretinal antibodies detected nor could virus be cultured from the biopsy specimen. The clinical appearance of this entity is distinctive and consists of a chronic posterior uveitis with transient initial yellow-white deep retinal lesions and the later development of large white subretinal fibrotic areas. The EOG is markedly decreased. We hypothesize that the immunologic events involved in this entity include antibody production with immunoglobulin and complement deposition leading to retinal and retinal pigment epithelial destruction and a subretinal fibrous proliferation.

Abstract
An immunoperoxidase technique was utilized to identify herpes simplex type I viral antigens in the retina, optic nerve and brain of an adult with herpetic retinitis and encephalitis. Viral antigens were demonstrated in all layers of retina, retinal pigment epithelium and to a lesser extent, in choroid. Oligodendroglia in the right optic nerve and neuronal and glial cells in the grey and white matter of the left frontal, inferior parietal and temporal lobes of the brain also expressed herpes simplex antigens. The sensitive immunoperoxidase method allowed detection of viral antigens in many cells without intranuclear inclusions or surrounding inflammation, and thereby added valuable information regarding the anatomic and cellular localization of herpetic infection. The clinicopathologic features that characterize herpes simplex retinitis in the adult are compared to cytomegalovirus retinopathy.
