  2. 1. Retinal Vein Occlusion A clinical study of electrophysiology, certain prognostic factors and treatment

    Author : Charlotte Lindberg; Lund Oftalmologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ophtalmology; Oftalmologi; multifocal electroretinography vitrectomy; electroretinography; factor V Leiden; retinal vein occlusion; prognostic factors;

    Abstract : The influence of the factor V Leiden mutation on the development of neovascular complications in central retinal vein occlusion was studied. The presence of the mutation was found to enhance the risk of developing neovascular complications almost threefold compared to in patients without the mutation. READ MORE

  4. 2. Experimental porcine models of retinal ischemia

    Author : Håkan Morén; Lund Oftalmologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; retinal ischemia; animal model; multifocal electroretinography; intraarterial coiling; retinal vasculature;

    Abstract : Retinal ischaemia resulting from e.g. diabetes, vein thrombosis or arterial occlusion, is one of the major causes of visual impairment and blindness. Although new methods of treatment are being developed, there is still a need for more effective pharmacological forms of treatment. READ MORE

  5. 3. Central retinal vein occlusion: Cetrain risk factors, electroretinography and an experimental treatment model

    Author : Jörgen Larsson; Lund Oftalmologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; flicker; ERG; electroretinography; fluorescein angiography; rubeosis; CRVO; central retianl vein occlusion; ultrasound; streptokinase; experimental; Ophtalmology; Oftalmologi;

    Abstract : The presence of activated protein C resistance, plasma hyperhomocysteinemia and the MTHFR C677T mutation in patients with central retinal vein occlusion were investigated and compared to a control group. Activated protein C resistance was overrepresented in the group of patients less than 50 years of age whereas this was not the case in patients more than 50 years of age. READ MORE

  6. 4. Central retinal vein occlusion : treatment with bevacizumab and its seasonal characteristics

    Author : David Epstein; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Central retinal vein occlusion (CRVO) is a retinal vascular disorder that may cause severe visual impairment. When CRVO occurs the venous blood flow is impeded with elevated intraluminal pressure upstream to the occlusion. READ MORE

  7. 5. Experimental inhibition of proliferative retinopathy

    Author : Sylvia Almlöf Sarman; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Retinal ischemic diseases like retinopathy of prematurity (ROP), diabetic retinopathy (DRP) and retinal vein occlusion, with preretinal neovascularization (angiogenesis) that may lead to vitreous hemorrhages and retinal detachment with subsequent vision loss and blindness is a global health problem. By analyzing the potential role of molecules acting at different levels of the angiogenic cascade the presented studies aimed to widen our understanding of retinal ischemic diseases on a molecular, cellular and morphologic level.
