    Abstract : The childhood eye cancer retinoblastoma originates from the retina and its development is initiated while the foetus is in the uterus. Retinoblastoma has a reported incidence of 1 in 15-18 000 live births, and approximately 90% of all patients are diagnosed before the age of 5. READ MORE

  4. 2. Clinical and Experimental Approach to the Benefits and Risks of Laser Treatment for Diabetic Macular Edema

  5. 3. Real-time multi-exposure laser speckle contrast imaging of skin microcirculatory perfusion

    Author : Martin Hultman; Ingemar Fredriksson; Marcus Larsson; Tomas Strömberg; Anne Heurtier; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multi-exposure laser speckle contrast imaging; Microcirculatory perfusion; Machine learning;

    Abstract : The microcirculation, the blood flow in the smallest blood vessels in the body, has a vital function as this is where oxygen and nutrients diffuses from the blood to to the surrounding cells. An important quantity is the tissue perfusion, a measure of the microcirculation’s capacity to provide oxygen and nutrients to the cells. READ MORE

    Author : Fredrik Källmark; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Microperimetry; fixation gaze pattern; scanning laser ophthalmoscope; visual field; scotoma; eclipse retinopathy.;

    Abstract : Our visual world is composed of images of colours, textures, edges and contrasts. In addition, these images may be moving or flickering. The goal of visual testing is to quantify these functions. READ MORE
