  1. 6. Genetic factors predisposing to myasthenia gravis and related autoimmune disorders

    Författare :Ryan Ramanujam; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Myasthenia gravis (MG) is an autoimmune disorder in which patients experience weakness of the skeletal or ocular-bulbar muscles. In most patients, anti-AChR antibodies affect the signal across the neuromuscular junction necessary for muscular contraction. LÄS MER

  2. 7. 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. 8. Optic nerve hypoplasia in children : prevalence, associated disorders and genetic causes

    Författare :Sara Dahl; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Optic nerve hypoplasia (ONH) is a congenital ocular malformation with a thin optic nerve in one or both eyes. ONH has been associated with neurodevelopmental disorders and pituitary dysfunction, but the prevalence of these comorbidities are still unknown, especially in children with less severe visual impairment and unilateral disease.

  4. 9. Visual dysfunction and ocular signs associated with periventricular leukomalacia in children born preterm

    Författare :Lena Jacobson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :preterm; retinopathy of prematurity; periventricular leukornalacia; magnetic resonance imaging; delayed visual maturation; visual acuity; crowding; visual field; cognitive visual dysfunction; optic disc; cupping; eye movements; nystagmus; strabismus; reading;

    Sammanfattning : The immature visual system is vulnerable to adverse events in infants born preterm. Both retinopathy of prematurity and periventricular leukomalacia may affect visual function and ocular appearance. LÄS MER

  5. 10. Evaluation of the visual pathway with ERG, mfERG and mfVEP in inherited eye disorders

    Författare :Lotta Gränse; Lund Oftalmologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; multifocal ERG; Full-field ERG; multifocal VEP; Bothnia Dystrophy; Retinitis pigmentosa; Dominant optic atrophy; Leber`s hereditary optic neuropathy; Oftalmologi; Ophtalmology;

    Sammanfattning : This thesis will describe the clinical phenotypes, with emphasis on electrophysiology, in patients with different hereditary eye diseases and to further evaluate and modify the mfVEP technique for clinical use. Bothnia Dystrophy is a tapetoretinal disorder with a mutation in the RLBP1 gene. LÄS MER
