  1. 1. Long-term outcome after cataract surgery : a longitudinal study

    Författare :Britta Lundqvist; Eva Mönestam; Ulf Stenevi; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cataract; cataract surgery outcome; longitudinal study; subjective visual acuity; Ophtalmiatrics; Oftalmiatrik; Ophtalmology; oftalmiatrik;

    Sammanfattning : Background Cataract surgery is the most common surgical procedure carried out in the developed world and surgery volumes have increased considerably during the last decades. Various aspects of the surgical procedure, including surgical incision size and intraocular lens materials, have changed substantially, improving the safety and the quality of the outcome. LÄS MER

  3. 2. Wavefront Aberrations and Peripheral Vision

    Författare :Linda Lundström; Peter Unsbo; Austin Roorda; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optics; Human eye; Aberrations; Peripheral vision; Central visual field loss; Optics; Optik;

    Sammanfattning : Failing eyesight causes a dramatic change in life. The aim of this project is to help people with large central visual field loss to better utilize their remaining vision. Central visual field loss means that the person has to rely on peripheral vision since the direct vision is lost, often due to a dysfunctional macula. LÄS MER

  4. 3. Investigations or perimetry and gaze-stability in healthy and deceased retina

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

    Sammanfattning : 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. LÄS MER

  5. 4. Patient-reported and medical outcomes in patients treated for diabetic macular edema : A real-world longitudinal study

    Författare :Therese Granström; Janeth Leksell; Anna Forsberg; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diabetes mellitus; Patient-reported outcomes; Retinopathy; Macular edema; Anti-VEGF treatment; Medicinsk vetenskap; Medical Science; Hälsa och välfärd;

    Sammanfattning : Background Diabetes mellitus can lead to complications, when the complication affects the eyes it is called retinopathy. This can affect the macula and lead to severe loss of vision, diabetic macular edema (DME). This condition has traditionally been treated with laser. LÄS MER
