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 ... -
Cherenkov luminescence imaging for assessment of radioactive plaque position in brachytherapy of uveal melanoma: An in vivo feasibility study
Krohn, Jørgen Gitlesen; Chen, Yi-Chun; Stabo-Eeg, Nils Ole; Hamre, Børge (Journal article; Peer reviewed, 2020)Purpose: To study the feasibility of using Cherenkov luminescence imaging (CLI) to evaluate and document ruthenium-106 plaque position during brachytherapy of uveal melanoma. Methods: Ruthenium-106 decays by emitting ... -
Nonsupine positioning after macular hole surgery: A prospective multicenter study
Lindtjørn, Birger; Krohn, Jørgen Gitlesen; Austeng, Dordi; Fossen, Kristian; Varhaug, Pål; Basit, Samy; Helgesen, Ole Harald; Eide, Geir Egil; Forsaa, Vegard Asgeir (Peer reviewed; Journal article, 2019)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 ... -
