Widefield Optical Coherence Tomography Angiography in Diabetic Retinopathy

Figure 2

Multimodal imaging of proliferative diabetic retinopathy (PDR). (a) Widefield optical coherence tomography angiography (WF-OCTA) of the posterior pole, revealing multiple neovascularization elsewhere (NVEs) and capillary nonperfusion (NP) temporal to the macula. (b) Structural B-scan passing through the area corresponding to the upper red dashed line. Temporally, NVE is discernible on the B-scan. (c) Structural B-scan passing through the fovea, corresponding to the lower red dashed line and showing temporal retinal thinning secondary to retinal ischemia. (d) Color fundus picture of the same patient, revealing macular exudates, cotton wool spots, and preretinal hemorrhages. (e) Fundus fluorescein angiography shows microaneurysms, capillary nonperfusion, and NVE.
