A representative case of a 31-year-old female patient with macula-off RRD in her right eye who underwent vitrectomy combined with SO tamponade. The duration of SO tamponade was 76 days. The BCVA before SO removal was 0.5 LogMAR (operated eye) and 0 LogMAR (fellow eye). After SO removal, the BCVA was 0.4 LogMAR (operated eye) and 0 LogMAR (fellow eye). The IOP before SO removal was 10 mmHg (operated eye) and 13 mmHg (fellow eye), while after SO removal it was 11 mmHg (operated eye) and 12 mmHg (fellow eye). The calculation of CVI using binarization of OCT images is shown. The CVI is obtained by dividing the luminal area by the total choroidal area. (A) Displays the CVI of the operated eye before SO removal, with a CVI (%) value of 58.416 (1.26467/2.16496). (B) Shows the CVI of the fellow eye at the same time point as A, with a CVI (%) value of 63.171 (1.38585/2.19383), which is higher than A. (C) Demonstrates the CVI of the operated eye after SO removal, with a CVI (%) value of 59.590 (1.36166/2.28504), which is higher than A. D) Exhibits the CVI of the fellow eye at the same time point as C, with a CVI (%) value of 62.516 (1.35600/2.16904), which is higher than C
