Fig. 6From: Near-infrared reflectance imaging of neovascularization in proliferative diabetic retinopathyNIR sequence of NVD imaging over 4Â years. Baseline active NVD on both NIR a and fluorescein angiography b. NIR displays hyporeflective neovascularization in greater detail compared to early phase angiography. At 6Â months from baseline, it is possible to identify in NIR c new hyporeflective vascular buds (arrows), corresponding to neovascular growth that involuted after laser treatment (d), shown by the reduced dark perfusion of the vessels in NIR (box). During follow-up, NIR e shows subsequent progression (arrows) and regression (f, g), after laser. Fluorescein angiography h at the same time as g is in accordance with NVD regressionBack to article page
