      East Asia has experienced an excessive increase in myopia in the past decades with more than 80% of the younger generation now affected. Environmental and genetic factors are both assumed to contribute in the development ...
    • The Retina in Congenital Aniridia - Structural, Functional and Genetic Variability 

      Pedersen, Hilde Røgeberg (Doctoral dissertations at the University of South-Eastern Norway;67, Doctoral thesis, 2020-05-12)
      Aniridia is a rare, congenital eye disorder most commonly caused by a mutation in the PAX6 gene, which affects eye development and leads to a range of ocular anomalies, including iris- and foveal hypoplasia and vision ...
    • Single-cone imaging in inherited and acquired colour vision deficiencies 

      Baraas, Rigmor C.; Pedersen, Hilde Røgeberg; Hagen, Lene Aarvelta (Journal article; Peer reviewed, 2019)
      Colour vision deficiencies are common in humans and occur both as a consequence of inherited cone opsin mutations, altering the number or function of the different cone types expressed in the retina, and acquired through ...
