β—coefficient from the regression model, SE—standard error, p < 0.05 highlighted with bold. n = 140 eyes (13 eyes with subretinal fluid, 89 eyes with cystoid macular oedema, and 38 eyes with diffuse macular oedema). Covariates included in each model: age in years, sex (male/female), DR (NPDR/PDR), PRP (no/yes). CVI = choroidal vascularity index; LA = luminal area; SA = stromal area; TCA = total choroidal area.
