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

Postoperative Evaluation of Retinal and Choroidal Perfusion in Diabetic Tractional Retinal Detachment

“…The impaired blood flow associated with subfoveal DRIL generated by decreased blood perfusion combined with cell apoptosis due to retinal ischemia, which is mainly associated with lower-than-normal VD values in the SCP, CVI, and CFA, contributes to poor postoperative visual results. A large FAZ area associated with poor visual acuity (VA) recovery is a common outcome [27,28,49].…”

“…The dark-to-light pixel ratio is then expressed as a percentage and defined as the CVI, as previously described by Agrawal et al [29,30]. The protocol study method for binarization was validated in a previous study [28]. The CFA is obtained by automated binarization and segmentation of the CSP slabs using the RTVue XR OCT Avanti with AngioVue Software (OptoVue Inc., Fremont, CA, USA) and automatically calculated from a 3.142 mm 2 evaluation area (Figure 4d).…”
