Cytomegalovirus Anterior Uveitis.

Aim:  The aim of the article is to summarize observations on cytomegalovirus (CMV) anterior uveitis, and in short case reports present cases of patients treated at our Department of Ophthalmology, First Faculty of Medicine, Charles University and General University Hospital in Prague.

Material And Methods:  Retrospective analysis of patients at the Centre for diagnosis and treatment of uveitis from 2003 to 2024. Presentation of our experiences with CMV anterior uveitis confirmed by polymerase chain reaction (PCR) in aqueous humor in case reports.

Blau Syndrome: Challenging Molecular Genetic Diagnostics of Autoinflammatory Disease.

The aim of this study was to describe the clinical and molecular genetic findings in seven individuals from three unrelated families with Blau syndrome. A complex ophthalmic and general health examination including diagnostic imaging was performed. The mutational hot spot located in exon 4 was Sanger sequenced in all three probands.

Association of Fuchs Heterochromic Iridocyclitis with Multiple Sclerosis.

Purpose: To draw attention to the higher proportion of Fuchs heterochromic iridocyclitis (FHI) cases in patients with multiple sclerosis (MS).

Materials And Methods: Retrospective study of data collected at the Center for the Diagnosis and Treatment of Uveitis.

Results: An analysis of the medical records of 3016 patients with uveitis (in the years 2003-2020) was performed with a focus on MS.

Experimental model of primary intraocular lymphoma based on BALB/CaNn strain and A20 cells is optimal for investigational research.

Aim: The purpose of this project was to compare the characteristics of two experimental murine models of primary intraocular lymphoma (PIOL) and determine which experimental model is most suitable for further investigational research to elucidate the pathophysiology of PIOL and to find new therapeutical strategies.

Methods: In both experimental models PIOL was induced in immunocompetent mice with intravitreal injection of syngeneic B-cell lymphoma cell lines. Murine strain C3H/HeN and cell line 38C13 were used in the first model and BALB/CaNn mice and cell line A20 in the second model.

The Prevalence of MRI-Defined Sacroiliitis and Classification of Spondyloarthritis in Patients with Acute Anterior Uveitis: A Longitudinal Single-Centre Cohort Study.

Background: Acute anterior uveitis (AAU) is a relatively common extra-musculoskeletal manifestation of axial spondyloarthritis (axSpA); however, data on the prevalence of active sacroiliitis in patients with AAU are limited.

Methods: 102 patients with AAU and 39 healthy subjects (HS) underwent clinical assessment and sacroiliac joint MRI. Patients with absence of active sacroiliitis were reassessed after two years.

Severity of Experimental Autoimmune Uveitis Is Reduced by Pretreatment with Live Probiotic Nissle 1917.

Non-infectious uveitis is considered an autoimmune disease responsible for a significant burden of blindness in developed countries and recent studies have linked its pathogenesis to dysregulation of the gut microbiota. We tested the immunomodulatory properties of two probiotics, Nissle 1917 (EcN) and O83:K24:H31 (EcO), in a model of experimental autoimmune uveitis (EAU). To determine the importance of bacterial viability and treatment timing, mice were orally treated with live or autoclaved bacteria in both preventive and therapeutic schedules.

Infectious uveitis in immunodeficient HIV-negative patients: A retrospective study.

Aims: Cases of infectious uveitis in immunodeficient patients may present with atypical clinical features because the clinical course of disease is usually affected by the compromised immune system. Therefore, it is sometimes difficult to determine the correct diagnosis. The aim of this study was to evaluate a prevalence of immunodeficient HIV-negative individuals among patients with infectious uveitis and to assess diagnostic and therapeutic approaches.

Combined treatment of primary vitreoretinal lymphomas significantly prolongs the time to first relapse.

Background: Vitreoretinal lymphomas belong to the family of central nervous system (CNS) lymphomas. The optimal approach for the treatment of isolated primary vitreoretinal lymphoma is unclear because of the lack of large comparative clinical series. Combination of intravitreal and systemic chemotherapy is recommended in many reports.

The Microbiota Determines Susceptibility to Experimental Autoimmune Uveoretinitis.

The microbiota is a crucial modulator of the immune system. Here, we evaluated how its absence or reduction modifies the inflammatory response in the murine model of experimental autoimmune uveoretinitis (EAU). We induced EAU in germ-free (GF) or conventionally housed (CV) mice and in CV mice treated with a combination of broad-spectrum antibiotics either from the day of EAU induction or from one week prior to induction of disease.

The critical points in induction of experimental autoimmune uveitis.

Background: Autoimmune uveitis is a leading cause of visual impairment in developed countries in patients of working age. Animal models of experimental autoimmune uveitis (EAU) have been established to serve as a useful template for novel therapeutic approaches.

Methods: Experimental autoimmune uveitis is induced in C57BL/6 mice by subcutaneous application of interphotoreceptor retinoid binding protein in complete Freund's adjuvant and pertussis toxin.
