Retinal Layers Changes in Human Preclinical and Early Clinical Diabetic Retinopathy Support Early Retinal Neuronal and Müller Cells Alterations
Figure 4
Spectral domain OCT linear scans in the macula of (a) normal subject, (b) diabetic patient without retinopathy, and (c) diabetic patient with mild nonproliferative diabetic retinopathy. The arrows indicate a progressive thinning of the retinal nerve fiber layer in diabetics (without and with retinopathy) versus normal subjects.
