Kompetanse

Aniridi er en medfødt genetisk øyetilstand som gjør at regnbuehinnen (iris) mangler helt eller delvis, men som også fører til en underutvikling i flere av øyets strukturer, deriblant netthinnen. Tilstanden medfører betydelig nedsatt syn, men det er stor variasjon fra person til person. Per i dag trengs det mer kunnskap rundt denne tilstanden for å kunne gi alle med aniridi den behandlingen og de rådene de har behov for. Målet med mitt phd-prosjekt er å undersøke variasjon i netthinnens utvikling og genotype hos personer med aniridi, og se på hvordan dette påvirker synsfunksjonen. Til dette bruker vi blant annet avansert avbildningsteknologi til å ta bilder av ulike cellelag og sansecellene på netthinnen. Målet er å bidra til økt kunnskap om utvikling av netthinnen som igjen kan bidra til bedre persontilpasset oppfølging, råd og synsrehabilitering.

Interesseområder:

  • Adaptiv optikk oftalmokopi for avbildning av enkelt celler på øyets netthinne
  • Aniridi
  • Sammenheng mellom netthinnestruktur og synsfunksjon
  • Farge- og detaljsyn
  • Netthinnedystriofier og genetikk
  • Øyets optikk
  • Personorientert helsearbeid

Hilde R. Pedersen studied Optometry and Vision Science at Buskerud University College, Kongsberg, Norway. She graduated in 2006, and worked as an optometrist in private practice for eight years. She completed a Master of Science in Optometry and Visual Science in June 2015. Since autumn 2015 she worked as a lecturer and research assistant at the Department of Optometry and Visual Science at the University College of Southeast Norway. She received a 3-year PhD-fellowship in september 2016 (staring January 2017), to undertake postgraduate research in the Colour Vision and Retinal Imaging Laboratory (the CVRI Lab) with professor Rigmor C. Baraas. Her research interests are related to retinal structure-visual function relationship in normal healthy eyes and eyes with retinal dysfunction.
