Correction: Postoperative choroidal vascularity index after the management of macula-off rhegmatogenous retinal detachment

Fig. 3 figure 3 a Optos wide-angle photograph of a normal control eye. a1 Enhanced high-definition (HD) 9-mm horizontal B-scan designed to depict details of the intraretinal structure and subfoveal choroidal layers in a normal eye. a2 Corresponding horizontal B-scan with binarized processing of the subfoveal choroidal stroma and luminal vascular visualization of the subfoveal choroidal vessels for obtaining the choroidal vascularity index (CVI) of a normal emmetropic eye. After 18 months of postoperative follow-up, the operated eye showed a best corrected visual acuity of 20/40 (logMAR 0.30). c1 A long-term postoperative horizontal B-scan through the fovea depicts a normal foveal profile with sclerotic, medium-sized choroidal vessels. c2 Corresponding horizontal B-scan binarized image of the subfoveal choroidal stroma and luminal vascular visualization of the subfoveal choroidal vessels depicting a lower-than-normal choroidal perfusion index in the fellow eye. d Postoperative image of a representative eye from the buckle group. The participant was a 49-year-old male who presented with a 3-day history of progressive metamorphopsia and acute vision loss due to an acute superior-in-origin rhegmatogenous RD due to superior trophic holes inside an area of lattice zone degeneration, with evidence of acute posterior vitreous detachment and a bullous rhegmatogenous macula-off RD.
