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.

PATHOGENESIS AND CURRENT METHODS OF TREATMENT OF SECONDARY UVEITIC GLAUCOMA. A REVIEW.

Secondary uveitic glaucoma is a serious sight-threatening complication of intraocular inflammation (uveitis). It develops in approximately 10-20% of patients with uveitis (although this figure may be higher depending on the type of inflammation). It is more commonly associated with chronic forms of uveitis, especially anterior uveitis.

MICROBIOME AND UVEITIDES. A REVIEW.

Microorganisms inhabiting all surfaces of mucous membranes and skin and forming a complex ecosystem with the host is called microbiota. The term microbiome is used for the aggregate genome of microbiota. The microbiota plays important role in the mechanisms of number of physiological and pathological processes, especially of the hosts immune system.

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.

IMMUNE-MEDIATED INTRAOCULAR INFLAMMATION. A REVIEW.

Immune mediated inflammatory diseases are categorized into autoimmune and autoinflammatory. Autoimmune etiology is represented by autoreactive lymphocytes or autoantibodies, e.g.

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.

Acute elevation of intraocular pressure in patient with hyperlipidemic myeloma.

Purpose: To introduce a rare case of patient with hyperlipidemic myeloma and ocular manifestation in form of masquerade syndrome with acute elevation of intraocular pressure (IOP) and hyperviscous retinopathy.

Results: 55-year-old man with newly diagnosed hyperlipidemic myeloma and hyperviscous syndrome was acutely referred to our glaucoma outpatient clinic due to problems with his left eye: sudden pain, blurred vision, redness of the eye and IOP of 44 mm Hg. We excluded attack of angle closure glaucoma and found presence of whitish material in the anterior chamber and blood obstructing the iridocorneal angle.

Recommendations for the Management of Uveitis Associated With Juvenile Idiopathic Arthritis: The Czech and Slovak adaptation of SHARE Initiative.

Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease in children and uveitis is its most important extra-articular manifestation. Evidence-based recommendations are available only to a limited extent and therefore JIA associated uveitis management is mostly based on physicians experience. Consequently, treatment practices differ widely, both nationally and internationally.

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.

Ocular Manifestations of Granulomatosis with Polyangiitis.

Granulomatosis with polyangiitis (GPA), formerly known as Wegeners granulomatosis, is an autoimmune vasculitis of small vessels, presenting as necrotizing granulomatous inflammation especially of the upper and lower respiratory tract and necrotizing glomerulonephritis. GPA affects more often Caucasians in northern states, predominantly is affected the age-range group of 50 - 60 years. GPA may affect any organ; the eye symptoms are stated in the range of 16-78 %.

Metronidazole Attenuates the Intensity of Inflammation in Experimental Autoimmune Uveitis.

Autoimmune uveitis is a serious sightthreatening disease that in many cases fails to respond to conventional immunosuppressive or biological therapy. Experimental models used in research allow more detailed study of pathogenesis of the autoimmune process and testing new therapeutic strategies. Recent results show that infection can trigger autoimmune diseases, and some commensal microorganisms are essential in causing disease activity.

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.

[TATTOO-ASSOCIATED UVEITIS].

The clinical case of tattoo-associated uveitis was first described by Lubeck and Epstein in 1952. Uveitis is accompanied by induration and hyperemia of tattoo skin, which can precede, follow or manifest simultaneously with uveitis. The diagnosis is determined on clinical grounds after exclusion of other causes.

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 Clinical Signs of Experimental Autoimmune Uveitis].

Introduction: Autoimmune uveitis is a sight threatening disease which in many cases fails to respond to conventional immunosuppressive or biological therapy. The research in experimental models of autoimmune uveitis helps to find new therapeutical strategies. The aim of this study is to present the clinical and histological signs of experimental autoimmune uveitis (EAU) in mice.

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.

[Cytomegalovirus retinitis in HIV negative patients - retrospective study].

Aim: To evaluate own experience with the diagnosis and treatment of cytomegalovirus (CMV) retinitis in HIV negative patients with immunodeficiency.

Methods: Retrospective study and case reports.

Results: In the Centre for diagnosis and treatment of Uveitis 1869 patients with uveitis we have examined from June 2003 to June 2012.

Mycophenolate mofetil and cyclophosphamide treatments suppress inflammation intensity in an experimental model of autoimmune uveitis.

In human, autoimmune uveitis is a leading cause of visual disability and ranks with diabetic retinopathy as a major source of blind registrations in developed countries. Since most cases of non-infectious uveitis are considered to be autoimmune or at least immune-mediated, the management of such patients has rested on appropriate immunosuppression. Some patients, however, despite maximal immunotherapy, fail to respond or are seriously intolerant of the drug therapies.

[Retinitis pigmentosa mimicking uveitis. A case report].

Purpose: To describe a case report of a 23-year-old patient with retinitis pigmentosa (RP) misdiagnosed as uveitis.

Methods: A comprehensive eye examination including automated visual field assessment, contrast sensitivity, colour vision discrimination, ultrasound examination (US), spectral domain optical coherence tomography (SD-OCT) and full-field electroretinography (ERG) was performed in a patient diagnosed elsewhere as having intermediate uveitis because of the observation of a cellular reaction in the anterior chamber, bilateral cystoid macular oedema and suspected left optic disc swelling.

Results: The patient reported nyctalopia.
