Choroidal vascularity index across study groups

Optical coherence tomography images were analyzed using ImageJ to obtain the luminal area (LA) and total choroidal area (TCA). The choroidal vascularity index (CVI) was calculated by dividing LA by TCA and was presented as a percentage. CVI was significantly lower in the buckling group and higher in the vitrectomy group than in the emmetropic group. The mean ± standard deviation is plotted; * p ≤ 0.05, ** p ≤ 0.01, and **** p ≤ 0.0001
