Ocular antigens are sequestered behind the blood-retina barrier and the ocular environment protects ocular tissues from autoimmune attack. The signals required to activate autoreactive T cells and allow them to cause disease in the eye remain in part unclear. In particular, the consequences of peripheral presentation of ocular antigens are not fully understood. We examined peripheral expression and presentation of ocular neo-self-antigen in transgenic mice expressing hen egg lysozyme (HEL) under a retina-specific promoter...

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 PRESENTATION: We present a case wherein a 62-year-old Japanese rheumatoid arthritis woman, with HSV uveitis, presented with hemorrhagic hypopyon in the anterior chamber and a fever with photophobia...

Varicella zoster virus (VZV)-induced anterior uveitis (AU) may complicate the course of primary varicella infection typically seen in children. In adults, especially with advanced age, VZV AU is more commonly associated with herpes zoster ophthalmicus (HZO) with or without skin rash affecting the distribution of the ophthalmic nerve due to reactivation of the latent VZV in the trigeminal ganglion. While it is typically a mild self-limiting AU in primary infection, HZO AU is often accompanied by keratitis, may have a chronic recurrent course, and lead to sectoral iris atrophy, pupillary distortion, and ocular hypertension...

The viral causes of anterior uveitis (AU) emerged with the use of novel molecular diagnostic tests and serologic tests adapted for small volumes (Goldmann-Witmer Coefficient). The viral causes of AU may be underestimated, and some of the presumed idiopathic AU cases will probably be proven to be of viral origin in the coming years. So far, a viral origin of AU was suspected in patients who presented with unilateral hypertensive AU. It is not clear which clinical presentations should raise a suspicion of viral etiology...

Cytomegalovirus (CMV) retinitis is a sight-threatening form of posterior uveitis affecting patients with Acquired Immunodeficiency Syndrome (AIDS), especially those with CD4 count <50 cells/mm3. There are few reported cases of CMV retinitis in patients with CD4 count >100 cells/mm3. Avirostatic agent like Ganciclovir has good response rate when given as intravitreal injection. Here, we report a case of CMV retinitis in a young immunocompetent male who presented with history of progressive loss of vision in both eyes despite receiving oral and intra-vitreal steroids...

PURPOSE: Success of Ebola virus (EBOV) as a human pathogen relates at the molecular level primarily to blockade the host cell type I interferon (IFN) antiviral response. Most individuals who survive Ebola virus disease (EVD) develop a chronic disease syndrome: approximately one-quarter of survivors suffer from uveitis, which has been associated with presence of EBOV within the eye. Clinical observations of post-Ebola uveitis indicate involvement of retinal pigment epithelial cells. METHODS: We inoculated ARPE-19 human retinal pigment epithelial cells with EBOV, and followed course of infection by immunocytochemistry and measurement of titer in culture supernatant...

BACKGROUND: Cataract is a leading cause of blindness worldwide. Cataract surgery is commonly performed but can result in postoperative inflammation of the eye. Inadequately controlled inflammation increases the risk of complications. Non-steroidal anti-inflammatory drugs (NSAIDs) and corticosteroids are used to prevent and reduce inflammation following cataract surgery, but these two drug classes work by different mechanisms. Corticosteroids are effective, but NSAIDs may provide an additional benefit to reduce inflammation when given in combination with corticosteroids...

Human T cell leukemia virus type 1, also known as human T lymphotropic virus type 1 (HTLV-1), is a retrovirus that encodes a reverse transcriptase, which translates viral RNA into a DNA provirus that is integrated into the host genome. The virus was found to be a causative agent of adult T cell leukemia/lymphoma (ATL) in the early 1980s, and was also found to cause the neurological disorder tropical spastic paraparesis (TSP)/HTLV-1-associated myelopathy (HAM) and the inflammatory disorder HTLV-1 uveitis in the mid 1980s and early 1990s, respectively...

Cytomegalovirus (CMV) is one of the infectious causes of hypertensive anterior uveitis, which is characterized by recurrent episodes of elevated intraocular pressure (IOP) and mild anterior uveitis. Despite the potentially vision-threatening complications of this disease, the underlying mechanisms remain largely undefined. We aimed to investigate whether human trabecular meshwork (TM) cells, the key cell type that regulates IOP, could support CMV replication, as well as demonstrate the relevant pathological changes in TM...

Acute retinal necrosis (ARN) is a rare viral inflammatory disease, characterized by uveitis, retinal vasculitis, and necrosis in the late stages. Therapeutic management is based on the clinical findings. The positive outcome in our patient (VA 0.6) indicates that, beside the management of retinal detachment and lens opacification, additional intravitreal injections of 2 mg ganciclovir may achieve better results than systemic/topical antiviral application alone.

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...
