Comparison of both methods for scleral indentation: Sections a–c represent the method used by surgeon A. Sections d–f represent the method used by surgeon B. a, d show schematic cross-sectional representations of the eyeball during each indentation method. In both cases the vitrectome is held intravitreally. In a, the light pipe cap serves as for indentation, while in d, a simple indentor is used with a chandelier light being held intravitreally for better visualization. b, e show overview images of the surgical fields of both indentation techniques, while c, f show a more detailed view from the perspective of the respective surgeon
