Ultra-widefield fluorescein angiography (UWFA) feature assessment with cytokine expression. A, Leakage feature assessment on baseline UWFA image for 1 eye in the high vascular endothelial growth factor (VEGF) group (super plus early responder) and low VEGF group (slow plus nonresponder). The centroid of the leakage patch is highlighted in red and the boundary of each of the leakage patches are highlighted in separate colors. Leakage patches with same area are presented using the same color. B, Vessel tortuosity assessment on baseline UWFA image for 1 eye in the high VEGF group and low VEGF group. As observed, vessels in the high VEGF group are more tortuous compared with the vessels in the low VEGF group. C, Feature map showing texture-based OCT-derived laws S5L5L5 feature for 1 eye from the high VEGF group and low VEGF group. Higher feature expression is observed for the high VEGF group.
