      Purpose: To assess color vision and its association with retinal structure in persons with congenital aniridia. Methods: We included 36 persons with congenital aniridia (10–66 years), and 52 healthy, normal trichromatic ...

    • The cone photoreceptor mosaic in aniridia: within-family phenotype-genotype discordance 

      Pedersen, Hilde Røgeberg; Neitz, Maureen; Gilson, Stuart; Landsend, Erlend Christoffer Sommer; Utheim, Øygunn Aass; Utheim, Tor Paaske; Baraas, Rigmor C. (Peer reviewed; Journal article, 2019)
      Purpose Investigate in vivo cone photoreceptor structure in familial aniridia caused by deletion in the PAX6 gene to elucidate the complexity of between-individual variation in retinal phenotype. Design Descriptive ...

    • Meibomian gland dysfunction and keratopathy are associated with dry eye disease in aniridia 

      Landsend, Erlend Christoffer Sommer; Pedersen, Hilde Røgeberg; Utheim, Øygunn Aass; Xiao, Jiaxin; Adil, Muhammed Yasin; Tashbayev, Behzod; Lagali, Neil; Dartt, Darlene Ann; Baraas, Rigmor C.; Utheim, Tor Paaske (Journal article; Peer reviewed, 2018)
      Aims To investigate the aetiology and characteristics of dry eye disease (DED) in a Nordic cohort of patients with congenital aniridia. Methods Thirty-four Norwegian and one Danish subject with congenital aniridia and 21 ...

    • Multimodal imaging of small hard retinal drusen in young healthy adults. 

      Pedersen, Hilde Røgeberg; Gilson, Stuart; Dubra, Alfredo; Munch, Inger Christine; Larsen, Michael; Baraas, Rigmor C. (Journal article; Peer reviewed, 2017)
      Background Small hard macular drusen can be observed in the retina of adults as young as 18 years of age. Here, we seek to describe the in vivo topography and geometry of these drusen. Methods Retinal images were acquired ...

    • Non-cycloplegic refraction cannot replace cycloplegic refraction when screening for refractive errors in children 

      Bjørset, Cecilie Onshuus; Pedersen, Hilde Røgeberg; Synstelien, Gro O.; Gilson, Stuart; Hagen, Lene Aarvelta; Langaas, Trine; Thorud, Hanne Mari Schiøtz; Vikesdal, Gro Horgen; Baraas, Rigmor C.; Svarverud, Ellen (Journal article; Peer reviewed, 2022)
      The purpose was to assess the differences in spherical equivalent refractive error (SER) between cycloplegic autorefraction (1% cyclopentolate), non-cycloplegic autorefraction, and non-cycloplegic retinoscopy measured by ...

    • PAX6 Genotypic and Retinal Phenotypic Characterization in Congenital Aniridia
