Abstract
A 4-year-old girl presented with acute left visual loss 4 weeks after uneventful chickenpox. She was found to have left necrotising retinitis and profound retinal vasculitis and vitritis. Aqueous humour was PCR positive for varicella-zoster virus. Combined intravenous and intravitreal antiviral treatment led to rapid improvement with settled retinitis, no vascular occlusion and good recovery of vision. Her recent coinfection with Epstein-Barr virus may have acted to provoke the retinitis.

Abstract
A necrotizing retinitis in children is a rare but vision-threatening ocular complication of chickenpox. We report a 10-year-old girl who developed chickenpox 1 month before presenting with panuveitis and necrotizing retinitis. After prompt antiviral treatment, her inflammatory signs were resolved. Early detection and treatment of varicella zoster-associated necrotizing retinitis after chickenpox can achieve good visual outcome.

Abstract
In immunocompetent individuals, necrotizing retinopathy is a rare complication of chickenpox. Herein, we report on a 3-year-old immunocompetent boy who developed retinitis and optic neuritis 3 days after the onset of chickenpox and compare the findings to published cases. Since macula and optic nerve were affected, visual acuity remained poor. An early diagnosis and treatment of ocular manifestations in chickenpox is imperative for the preservation of a residual visual function and prevention of blinding secondary complications.

Abstract
It is usual to consider chicken pox as a benign infectious disease with a few anterior segment ocular complications like conjunctivitis, keratitis, episcleritis, scleritis, iridocyclitis, and glaucoma. The retinal manifestations are necrotising retinitis, vitritis, neuroretinitis, and retinal detachments. We report a case of neuroretinitis following chicken pox in a 23-year-old male. The complication was resolved by treatment with oral acyclovir in combination with systemic steroids. This report highlights the necessity for fundus examination in cases of chickenpox exhibiting visual symptoms.

Abstract
Tumor necrosis factor alpha (TNF-alpha) has been shown to have a protective role in the eyes and brains of herpes simplex virus type 1 (HSV-1)-infected mice. To determine whether overexpression of TNF-alpha affected the course of virus infection following uniocular anterior chamber inoculation, a recombinant of HSV-1 that produces TNF-alpha constitutively (KOSTNF) was constructed. BALB/c mice were injected with the TNF-alpha recombinant, a recombinant containing the pCI plasmid, a recombinant rescue virus, or the parental virus. Flow cytometry and immunohistochemistry were used to identify virus-infected cells and to determine the numbers and types of infiltrating inflammatory cells in the uninjected eyes. Virus titers were determined by plaque assay. There were no differences among the groups in virus titers or the route and timing of virus spread in the injected eyes or in the suprachiasmatic nuclei. However, in the uninjected eyes of KOSTNF-infected mice, TNF-alpha expression was increased and there were more viral antigen-positive cells and immune inflammatory cells. There was earlier microscopic evidence of retinal infection and destruction in these mice, and the titers of virus in the uninjected eyes were significantly increased in KOSTNF-infected mice on day 7 postinfection compared with those of KOSpCI-, KOS6beta rescue-, or KOS6beta-infected mice. The results suggest that instead of moderating infection and reducing virus spread, overexpression of TNF-alpha has deleterious effects due to increased inflammation and virus infection that result in earlier destruction of the retina of the uninoculated eye.

Abstract
Acute retinal necrosis (ARN) is known to occur in conjunction with primary varicella or chickenpox infection. The majority of ARN cases reported in the literature were of milder form with mild to moderate vitritis, limited retinitis, and rare occurrence of retinal breaks or detachment that responded well to intravenous acyclovir, with or without oral prednisolone. We report a case of unilateral ARN with marked vitritis and retinal necrosis leading to retinal breaks following chickenpox in a 32-year-old healthy lady. This patient was successfully treated with intravenous acyclovir followed by oral acyclovir and orbital floor triamcinolone injections to contain the inflammation with barrier laser therapy to secure the retinal breaks with good visual outcome. This case is unusual in its severity, and to our knowledge, orbital floor triamcinolone therapy was not used earlier to contain ARN inflammation.

Abstract
Serious ocular disease following varicella (chickenpox) is rare in children. In addition, retinitis in children with hematologic malignancies may present a difficult diagnostic challenge because infectious retinitis may mimic leukemic involvement of the eye. We report a 7-year-old patient with T-cell acute lymphoblastic leukemia in remission who presented with visual complaints 2 weeks after developing chickenpox. Ophthalmologic evaluation revealed acute retinitis in the right eye. Prolonged therapy with acyclovir resulted in near complete recovery. Early diagnosis of VZV retinopathy and aggressive antiviral treatment is critical to prevent acute and long-term ocular sequelae.

Abstract
Bacterial, fungal, viral, and parasitic pathogens all cause systemic infection and can spread to the eye. Dissemination of pathogens via the bloodstream can lead to direct involvement of the eye. Visual loss is common in bacterial or fungal endophthalmitis, and toxoplasmosis is a major cause of ocular morbidity and poor vision after congenital or acquired infection. Some infections cause intraocular damage by indirect mechanisms (eg, HIV-mediated immunosuppression), leading to opportunistic infections such as cytomegalovirus infection, periocular nerve involvement due to leprosy, and hypersensitivity reactions in tuberculosis. Eye symptoms might indicate the outcome of an underlying infection, such as development of retinal ischaemia in severe malaria, which is associated with a poor prognosis. Successful outcome for patients with ocular infection depends on close collaboration between clinicians identifying and treating underlying disease, specialist ophthalmic review, and ophthalmic interventional skills (when needed).

Abstract
Following anterior chamber (AC) inoculation of BALB/c mice with the KOS strain of herpes simplex virus type 1 (HSV-1), or with H129, a neuroinvasive and neurovirulent strain of HSV-1, both strains of virus spread from the injected eye through the brain to cause retinitis. However, KOS-infected mice develop retinitis in the uninoculated eye only, whereas H129-infected mice develop bilateral retinitis. Previous studies have shown that infiltrating T-cells in the suprachiasmatic nuclei (SCN) of the hypothalamus of KOS-infected mice concomitant with or before virus protect KOS-infected mice from ipsilateral retinitis. To determine the timing of T cell infiltration and cytokine production in the brain of H129-infected mice, adjacent, frozen sections of the brain were immunostained for virus, T-cells, IL-2, TNF-alpha or IFN-gamma. T-cells infiltrated the brains of H129-infected mice and cytokines were produced in infected tissues. However, virus spread to the optic nerve and retina of both the inoculated and uninoculated eye before T-cells and cytokines were detected in the SCN of H129-infected mice. These results suggest that infiltrating T-cells in the SCN of H129-infected mice may arrive too late to prevent the spread of virus into the optic nerves and retinas and thus prevent development of bilateral retinitis in infected mice.

Abstract
Following uniocular anterior chamber (AC) inoculation of BALB/c mice with the KOS strain of herpes simplex virus type 1 (HSV-1), virus spreads from the injected eye to the ipsilateral suprachiasmatic nucleus (SCN) in the central nervous system (CNS) to infect the optic nerve and retina of the contralateral eye, and mice develop retinitis in that eye only. In contrast, after AC inoculation of BALB/c mice with the H129 strain of HSV-1, mice develop bilateral retinitis. The pathway(s) by which H129 spreads to cause bilateral retinitis is not known. To determine the route and timing of H129 spread after AC inoculation, BALB/c mice were injected in the AC of the right eye with 5 x 10(3) PFU of H129. Brains from 30 mice were sectioned on a brain matrix and the amount of virus in the brain and eyes was determined by plaque assay. Frozen sections were prepared from the eyes, brain, and trigeminal ganglia of an additional 30 mice, and HSV-1 antigen was detected by immunohistochemistry. After AC inoculation, H129 follows a pathway similar to KOS in the CNS, but H129 appears to spread more rapidly than KOS within the CNS. Unlike KOS, H129 is able to infect brain stem nuclei and H129-infected mice developed neurological impairments in addition to bilateral retinitis. The results of these studies suggest that the ability of H129 to spread rapidly in the CNS allows early virus infection of retino-recipient nuclei proximal to the contralateral and ipsilateral optic nerves. Early infection of retino-recipient nuclei, such as the SCN may allow virus to spread into the retinas before a virus-specific immune response can be induced.

Abstract
We recently cared for an 11-year-old child with acute retinal necrosis syndrome, an ophthalmologic condition characterized by the triad of anterior uveitis, occlusive retinal vasculitis and progressive peripheral retinal necrosis. Acute retinal necrosis syndrome occurs primarily in nonimmunocompromised adults as a result of reactivated herpes simplex or varicella-zoster virus infection. Antiviral and antiinflammatory therapy appears to reduce the incidence of vision-threatening retinal necrosis and involvement of the contralateral eye.
