Filter by:Background: Contrast-enhanced ultrasound (CEUS) visualization of the adventitial vasa vasorum. Late phase CEUS detect inflammation by visualizing microbubbles phagocytosed by monocytes. The inflammatory process of the vessel wall associated with perivascular angiogenesis at the time of deep venous thrombosis (DVT) and superficial vein thrombophlebitis (SVT) may important in the development of post-thrombotic syndrome (PTS). Therefore the investigators will test the value of CEUS to detect venous perivascular vascularization and inflammation in patients with acute DVT or SVT. Aims: To determine the presence and degree of venous perivascular vascularization and inflammation assessed with CEUS in patients with acute DVT or SVT, and compare this to controls without thrombosis. Expected results: The investigators hypothesize that venous perivascular vascularization and inflammation assessed by contrast agent enhancement can be quantified and will be significantly more pronounced in the perivascular tissue of the thrombotic vein than in the non affected vein and in controls, and will correlate with level of inflammatory markers and leg volume. Significance: These results would provide new information on the pathophysiological concept of thrombosis and thrombus resolution. It might help to better understand the pathophysiologic mechanisms that promote the development of chronic venous insufficiency and PTS.
Retinal neovascularization of diabetic retinopathy might be associated with genetic risk factors and environmental risk factors.
This study will evaluate the safety and efficacy of dexamethasone (OZURDEX®) as adjunctive therapy to ranibizumab (LUCENTIS®) compared with ranibizumab alone in the treatment of patients with choroidal neovascularization secondary to age-related macular degeneration
The objectives of this study are to evaluate the safety(first objective) and efficacy(second objective)of an experimental drug product,Stakel®, in the treatment of neovascular Age related Macular Degeneration (AMD). The drug product is activated in patients by exposure to light at a specific wavelength ("Vascular Targeted Photodynamic therapy", "VTP"). The exploratory objective is to assess whether it is possible to delay or reduce the requirement for anti Vascular Endothelium Growth Factor (anti VEGF) intravitreal therapy in the first 12 weeks after VTP. All subjects will have a 52 weeks safety follow up telephone call (Not for Adverse Events (AEs) collection).
The purpose of this study is to determine the effectiveness and safety of Interleukin-1-Receptor Antagonist eye drops for the treatment of corneal blood vessels.
Identify early markers of choroidal neovascularization (CNV) in the fellow eye of a patient with CNV in the other eye due to age-related macular degeneration with the expectation of being able to identify patients in need of intervention.
The purpose of this study is to determine the safety and efficacy of an ocular sirolimus (rapamycin) formulation in combination with Lucentis in patients with sub-foveal choroidal neovascularization secondary to age-related macular degeneration.
This pilot study is designed to assess the impact of ischemia/ diminished wound vascularization and stress on wound healing by comparing patterns of gene expression in specific cell types critical to wound healing biology, e.g. macrophages or endothelial cells.
The purpose of this study is to determine the safety and efficacy of an ocular sirolimus (rapamycin) formulation via different injection routes in patients with treatment-naive sub-foveal choroidal neovascularization secondary to age-related macular degeneration.
Intravitreal Bevacizumab is an effective treatment for choroidal neovascularization secondary to Angioid Streaks
