Retinal Capillary Nonperfusion on OCT-Angiography and Its Relationship to Kidney Function in Patients with Diabetes

Figure 2

Estimated glomerular filtrate rate (eGFR) and retinal nonperfusion (RNP). Linear regression between eGFR and RNP. 30° field of view (FOV) (a) and 60° FOV (b) quantification results show a statistically significant negative correlation between eGFR and 30° retinal RNP in all participants. Diamonds represent eyes of patients with diabetes without diabetic retinopathy. Circles represent eyes with diabetic retinopathy. Solid black line shows the linear fit of all eyes. Asterisk () highlights an outlier eye with low RNP and low eGFR.
