  1. 16. Biomechanics of the Human Eye and Intraocular Pressure Measurements

    Författare :Darja Ljubimova; Anders Eriksson; Anders Eklund; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; IOP; GAT; ocular biomechanics; corneoscleral envelope; finite element modelling; parametric analysis; Engineering mechanics; Teknisk mekanik;

    Sammanfattning : This thesis addresses the reliability of Goldmann-type applanation tonometers (GAT). It deals with the investigation of the relation between predicted intraocular pressure, IOPG and true pressure, IOPT. LÄS MER

  3. 17. Inhibitors of corneal inflammation and angiogenesis : Prospectives and challenges

    Författare :Pierfrancesco Mirabelli; Neil S Lagali; Beatrice Bourghardt Peebo; Francisco C Figueiredo; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Pathologic angiogenesis is involved in cancer and several blinding conditions such as wet age-related macular degeneration, proliferative retinopathies and corneal neovascularization.In these dieseases, the angiogenic triggers are hypoxia and inflammation, and both involve the main angiogenic mediator, which is Vascular Endothelial Growth Factor (VEGF).

  4. 18. New methods to evaluate the effect of conventional and modified crosslinking treatment for keratoconus

    Författare :Jeannette Beckman Rehnman; Christina Lindén; Anders Behndig; Per Hallberg; Jesper Hjortdal; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Keratoconus; crosslinking; light scattering; densitometry; keratometry; hysteresis; intraocular pressure; oftalmiatrik; Ophtalmology;

    Sammanfattning : Background: Today corneal crosslinking with ultraviolet-A photoactivation of riboflavin is an established method to halt the progression of keratoconus. In some cases, when the refractive errors are large and the visual acuity is low, conventional corneal crosslinking may not be sufficient. LÄS MER

  5. 19. Neuropeptides and neurotransmitters in keratocytes : importance in corneal wound healing processes

    Författare :Marta Sloniecka; Patrik Danielson; May Griffith; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; substance P; acetylcholine; migration; proliferation; apoptosis; corneal stroma;

    Sammanfattning : Background: The cornea is the outermost transparent layer of the eye and it is responsible for the majorityof the eye’s total focusing power. Keratocytes are the resident cells of the corneal stroma and their function isto produce extracellular matrix components and to take part in corneal healing after injury, which may occurdue to trauma, infection or surgery.

  7. 20. Surgical outcomes of phototherapeutic keratectomy on Epithelial basement membrane dystrophy, and the characterisation of Bowman´s Layer

    Författare :Johan Germundsson; Neil Lagali; Per Fagerholm; Jesper Hjortdal; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Background. Epithelial basement membrane dystrophy (EBMD) is a common disease of the anterior cornea that can lead to problems with vision and/or painful recurrent erosions of the corneal epithelium. Several treatment options have been used, but recurrence of EBMD after treatment is a problem. LÄS MER
