The purpose of these studies was to test the hypothesis that a selected polypharmacological approach for treating the prostanoid-mediated component of inflammatory diseases would produce a therapeutic effect superior to global inhibition of prostaglandin (PG) biosynthesis by aspirin-like drugs. The compound studied was AGN 211377, which had been previously shown to produce a superior effect on cytokine release from human macrophages compared with cyclooxygenase (COX) inhibitors. AGN 211377 antagonizes prostanoid prostaglandin D2 (DP)1, DP2, prostaglandin E2 (EP)1, EP4, prostaglandin F2α, and thromboxane A2 receptors but not anti-inflammatory EP2, prostaglandin I2, or EP3 receptors...

Uveitis is a potentially sight-threatening disease characterized by repeated cycles of remission and recurrent inflammation. The JAK/STAT pathway regulates the differentiation of pathogenic Th1 and Th17 cells that mediate uveitis. A SOCS1 mimetic peptide (SOCS1-KIR) that inhibits JAK2/STAT1 pathways has recently been shown to suppress experimental autoimmune uveitis (EAU). However, it is not clear whether SOCS1-KIR ameliorated uveitis by targeting JAK/STAT pathways of pathogenic lymphocytes or via inhibition of macrophages and antigen-presenting cells that also enter the retina during EAU...

INTRODUCTION: VKH disease is a chronic, bilateral, granulomatous panuveitis with potential involvement of neurological, auditory and integumentary systems. On the other hand, APMPPE is believed to be an immune-driven chorioretinal vascular disease characterized by multifocal, flat, grey-white placoid lesions at the level of the RPE. We describe a case with overlapping figures of both conditions. CASE DESCRIPTION: A 19-year-old female presented with unilateral blurry vision and was found to have clinical and IVFA findings consistent with APMPPE...

PURPOSE: To quantify retinal capillary density and morphology in uveitis using SD-OCTA. DESIGN: Cross-sectional, observational study METHODS: Healthy and uveitic subjects were recruited from two tertiary care eye centers. Prototype SD-OCTA devices (Cirrus, Carl Zeiss Meditec, Inc., Dublin, CA) were used to generate 3x3 mm(2) OCTA images centered on the fovea. Subjects were placed into 3 groups based on the type of optical microangiography (OMAG) algorithm used for image processing (intensity- and/or phase) and type of retinal segmentation (automatic or manual)...

Purpose. We aimed to investigate retinal and choroidal thickness in the eyes of patients with Fuchs' uveitis syndrome (FUS). Methods. Fifteen patients with unilateral FUS and 20 healthy control subjects were enrolled. Spectral domain optical coherence tomography (Spectralis HRA+OCT, 870 nm; Heidelberg Engineering, Heidelberg, Germany) was used to obtain retinal and choroidal thickness measurements. The retinal nerve fiber layer (RNFL) thickness, macular thickness, and choroidal thickness of the eyes with FUS were compared with the unaffected eye and the eyes of healthy control subjects...

Acute retinal necrosis (ARN), secondary to herpes simplex encephalitis, is a rare syndrome that can present in healthy individuals, as well as immuno-compromised patients. Most cases are caused by a secondary infection from the herpes virus family, with varicella zoster virus being the leading cause of this syndrome. Potential symptoms include blurry vision, floaters, ocular pain and photophobia. Ocular findings may consist of severe uveitis, retinal vasculitis, retinal necrosis, papillitis and retinal detachment...

The risk of severe eye problems has been found to increase significantly with age, particularly between the fifth and sixth decades of life. Cataracts, dry eye, neovascular age-related macular degeneration, diabetic retinopathy and retinal vein occlusion (RVO) are very common and very different age-related ocular diseases that reduce the patient's quality of life. The rationale for using corticosteroids to treat anterior and posterior ocular segment diseases is driven by inflammation. Dexamethasone, one of the most powerful corticosteroids available, is widely used for topical or intravitreal administration...

Behçet disease is a chronic relapsing multisystem inflammatory disorder. Ocular involvement is characterized by a bilateral recurrent non-granulomatous panuveitis and retinal vasculitis. Posterior segment findings vary during the course of the disease, in parallel with the relapsing and remitting intraocular inflammation. Structural alterations occur with increased disease duration. Fluorescein angiography is the gold standard in revealing the extent and severity as well as the leaky and/or occlusive nature of retinal vasculitis...

Intestinal microbes have profound effects on inflammatory autoimmunity in sites distant from the gut. The mechanisms whereby this happens are only now beginning to be understood and may include such diverse effects as innate stimulation of migrating immune cells and effects of circulating bacterial metabolites. Our studies add to this the demonstration that microbiota may provide a source of cross-reactive antigenic material that activates autoreactive lymphocytes within the gut environment. In a spontaneous model of autoimmune uveitis, T lymphocytes specific to a retinal autoantigen are activated through their specific antigen receptor in the gut and acquire the ability to fuel inflammatory autoimmunity in the eye...

Human leukocyte antigen (HLA)-B27-associated anterior uveitis (AU) is the most commonly diagnosed form of AU and represents the largest entity of non-infectious uveitis around the world. The most typical ocular manifestation associated with HLA-B27 consists of unilateral AU of acute onset. The HLA-B27-associated acute AU represents a distinct clinical entity occurring typically in young adults between the ages of 20 and 40 years. HLA-B27-associated acute AU is typically unilateral and lasts usually several weeks and diminishes within 3 months in the majority of patients...

Cytomegalovirus remains the most common infection after kidney transplant. We report cytomegalovirus retinitis and anterior uveitis, which developed consecutively within 1 year in a kidney transplant recipient. A 25-year-old man presented 5 months after transplant with decreased visual acuity in his left eye. Fundus examination revealed bilateral areas of necrotizing retinitis with intraretinal hemorrhages. The confirmation of cytomegalovirus disease was based on clinical findings and positive polymerase chain reaction for cytomegalovirus in plasma and in aqueous humor...
