The subjects of this study are 16,031 old adults aged over 65 years who had been diagnosed with diabetes. The demographic characteristics, diabetes and diseaserelated characteristics, social distancing and fear of COVID-19 according to the diabetic retinal examination were analyzed with chi-square test. Logistic regression analyses were used to examine the factors influencing diabetic retinal examination.
