New Diagnostic and Therapeutic Approaches for Preventing the Progression of Diabetic Retinopathy

Figure 2

Optical coherence tomography (OCT) features of diabetic retinopathy in comparison with a normal eye. (a, b) OCT images in the normal and diabetic eyes obtained using the Cirrus HD-OCT system, respectively. (c, d) OCT images, respectively, in normal and diabetic eyes also obtained using the Cirrus HD-OCT system with the enhanced depth imaging (EDI) technique. (e, f) OCT images obtained using a swept-source OCT (SS-OCT). Note that the signal quality is improved markedly, and the vitreomacular interface and the choroid-sclera junction become clear. (e) The SS-OCT image of normal eye allows enhanced visualization of choroidal thickness (red arrows). (f) The image of a patient with DR showed reduced choroidal thickness.
