  2. 1. Clinical Studies on Dark Adaptation: with Particular Reference to Carotid Artery Disease

    Author : Ulf Havelius; Oftalmologi (Malmö); []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; polycythemia; photoreceptors; phlebotomy; ocular blood flow; headache; dilation lag; dark adaptometry; dark adaptation; color Doppler imaging; carotid artery stenosis; carotid artery disease; carotid endarterectomy; pupil; pupillometry; retinal blood flow; Ophtalmology; Oftalmologi;

    Abstract : Purpose: To study dark adaptation in patients with symptomatic carotid artery disease or polycythemia before and after treatment. This necessitated determinations of pupillary changes as such may influence the findings. To determine whether changes in the retinal blood flow in light and darkness occur in healthy humans.

  4. 2. The cerebral circulation in preeclampsia : abnormalities in autoregulation and perfusion

    Author : Michael A Belfort; Karolinska Institutet; Karolinska Institutet; []
    Keywords : preeclampsia; eclampsia; autoregulation; cerebral perfusion pressure; Doppler; central retinal artery; ophthalmic artery; middle cerebral artery; magnesium sulfate; nimodipine; headache; scotomata;

    Abstract : Background: Eclampsia continues to be a major cause of maternal death. Abnormal cerebral blood flow and autoregulation may play an important role in the causation. Doppler ultrasound now allows assessment of the pathophysiology of preeclampsia, and the mechanisms of action of drugs used to treat it. READ MORE

  5. 3. 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

  6. 4. Cerebral blood flow distribution, collateral function and pulsatility in healthy and in patients with symptomatic carotid stenosis  : a magnetic resonance imaging approach

    Author : Laleh Zarrinkoob; Jan Malm; Anders Eklund; Khalid Ambarki; Sepideh Amin-Hanjani; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aging; Arterial pulsatility; Carotid stenosis; Cerebral arteries; Cerebral blood flow; Cerebral collateral blood flow; Circle of Willis; Phase contrast magnetic resonance imaging;

    Abstract : Background: For the detection and treatment of early cerebral vascular disease it is of paramount importance to first understand the normal physiology of the cerebral vasculature, and subsequently, to understand how and when pathology can develop from that. This is especially important as the population above 65 years of age is increasing and aging itself is an established risk factor for the development of cerebral vascular disease. READ MORE
