    • Air versus Sulfur Hexafluoride Gas Tamponade for Small and Medium-Sized Macular Holes: A Randomized Noninferiority Trial 

      Lindtjørn, Birger; Krohn, Jørgen Gitlesen; Haugstad, Marta; Stene-Johansen, Ingar; Austeng, Dordi; Basit, Samy; Fossen, Kristian Anker; Varhaug, Pål; Kvaløy, Jan Terje; Forsaa, Vegard Asgeir (Journal article; Peer reviewed, 2022)
      Purpose: To investigate whether air tamponade is noninferior to sulfur hexafluoride (SF6) gas tamponade for small (≤ 250 μm) and medium-sized (> 250 μm and ≤ 400 μm) macular holes (MHs). Design: Multicenter, randomized ...

    • Macular hole – surgical treatment, epidemiology, and risk of bilateral disease 

      Lindtjørn, Birger (Doctoral thesis, 2022-12-08)
      Bakgrunn: Makulahull er en tilstand som hemmer sentralsynet og gir redusert livskvalitet. Personer som har fått et makulahull i et øye, har økt risiko for å utvikle makulahull også i det andre øyet. De siste 30 årene har ...

    • Nonsupine positioning after macular hole surgery: A prospective multicenter study

      Purpose: To evaluate the postoperative closure rate of full-thickness macular holes (MHs) after nonsupine positioning, which means that the patients avoid upward gaze and a supine sleeping position, and to investigate the ...

    • Optical coherence tomography features and risk of macular hole formation in the fellow eye 

      Lindtjørn, Birger; Krohn, Jørgen Gitlesen; Forsaa, Vegard A. (Journal article; Peer reviewed, 2021)
      Background: To investigate the risk of primary macular hole (MH) in the fellow eye, and to evaluate baseline characteristics and optical coherence tomography (OCT) features that precede MH formation in the fellow ...
