Background/aim: Behcet's disease is genetically conditioned, immune-mediated multisystem occlusive vasculitis of small blood vessels, espesially venules, of unknown etiology. The aim of this study was to analyze the clinical features, disease activity and therapy of the patients with ophthalmologic manifestation of Behcet's disease., Methods: In this study symptoms and signs of the disease were analyzed both prospectively and retrospectively during the active manifestation of the disease. The diagnosis was reached according to the International Criteria for Behcet's Disease (2006). The treatment effects were evaluated based on the presence of the best corrected visual acuity and the inflammation of the vitreous humour before and after the application of our therapeutic method. The applied therapeutic modality consisted of the primary application of corticosteroid therapy in the active stage of the disease complemented with the choice of drugs from the immunosuppressive group. In this study there drugs were cyclosporine or methotrexate. A treatment refractory patients with poor vision prognosis were treated with a third drug, the biological preparation infliximab, a tumor necrosis factor-alpha (TNF-alpha) antagonist., Results: The mean age of 11 patients with ophthalmologic manifestation of Behcet's disease was 50.6 years. HLA B-5 (51) was positive in 81% of the patients while 36% of the patients had positive pathergy test. Changes in affected eyes included vitritis (100%), posterior uveitis (45%), panuveitis (54%), retinal vasculitis (54%), cystoid macular edema (54%), and cystoid degeneration (18%). Increased intraocular pressure was observed in 27% of the patients. There was no statistically significant variation in disease activity parameters in any of the patients (p > 0.05). A statistically significant improvement in visual acuity (p < 0.05) and a high statistically significant decrease of inflammation of the worst affected eyes (p = 0.001) were detected., Conclusion: Our therapeutic method is useful for producing the optimal therapeutic plan for the acute--chronic stage of the difficult ophtamological manifestation of Behcet's desease as well as the prevention of relapse. However the high cost of the therapy and the potential complications should be taken into consideration when prescribing this therapy, especially a TNF-alpha antagonist.

Background/aim: Vasculitis is a clinical, pathologic process characterized by inflammation and necrosis of blood vessel occuring anywhere in the body. The aim of the study was to present some clinical and immunologic features of retinal vasculitis in systemic diseases: systemic lupus erythematosus, multiple sclerosis, sarcoidosis, Behcet's diseases, and others., Methods: A total of 1 254 peatients with uveitis were included in the study. The immunochemical diagnostic methods were used to determine the pathogenesis of ocular manifestations. Ocular manifestations were examined using biomicroscope, direct or indirect ophtalmoscopy., Results: Primary retinal vasculitis was diagnosed in 85/1254 (6.8%) of total uveitis. In more than half of the cases of vasculitis (58.8%), both arteries and veins were involved in inflammatory process. Periphlebitis was diagnosed far more commonly (36.5%) than periarteritis (4.7%). Retinal vasculitis associated with systemic lupus erythematosus was characterized by microinfarctions and the consequent foci of inflammatory cells or diseases of large arteries manifesting in vasospasm and occlusions. Cotton wool spots occured in 38.3% and retinal hemorrhages in 34% of the cases. In this study periphlebitis of the retina was one of the less frequent ocular manifestations of multiple sclerosis. Comparing with the other changes of the retinal blood vessels, venous sheating occured in 25.1% and occlusion and vein thrombosis in 43.75% of the cases. Retinal vasculitis associated with chronic sarcoidosis occured in 37.5% of patients with sarcoidosis. The most frequent manifestation of ocular sarcoidosis was intermediary uveitis (43.75%). Anterior granulomatous uveitis occured in 37.5% of patients with sarcoidoses. Immune complexes occured in 13/20 (65%) of the patients. Antiretinal anti-S antibody in the serum occured in 73% of the patients with retinal detachment as a complication of primary disease and in 25% those with vasculitis., Conclusion: Systemic diseases such as Behcet's syndrome, collagen vascular diseases, systemic granulomatous diseases (sarcoidosis and tuberculosis) were the main causes of retinal vasculitis. Knowledge of the symptomatology and pathogenesis of retinal vasculitis is of the major significance for the diagnosis and therapy of the disease.
