Abstract: Objective To explore the consistency between Daytona ultra-wide-field scanning laser ophthalmoscope and fundus fluorescein angiography (FFA) in screening diabetic retinopathy (DR) in the elderly patients with cataract and diabetes mellitus (DM). Methods A cross-sectional study was conducted. A total of 172 (323 eyes) elderly patients with cataract complicated with DM aged ≥ 60 years old admitted to Ophthalmology Clinic of Daqing Oilfield General Hospital from April 2021 to August 2023 were enrolled in this study. Daytona ultra-wide-field scanning laser ophthalmoscope and FFA were applied to screen DR.The data were analyzed using chi-square test, weighted Kappa test and Spearman partial regression analysis. Results No significant difference was found in readability of fundus imaging betweeen Daytona ultra-wide-field scanning laser ophthalmoscope and FFA (93.8% vs. 94.1%, P=0.869).The examination duration of Daytona ultra-wide-field scanning laser ophthalmoscope was 2.3(1.7, 5.2) min, compared with 9.5(7.3, 12.0) min of FFA (Z=16.85, P<0.001). The complete consistency rate in determining DR stage between Daytona ultra-wide-field scanning laser ophthalmoscope and FFA was 93.29% (278/298) (Kappa=0.925, 95%CI: 0.892-0.958). The sensitivity and specificity of Daytona ultra-wide-field scanning laser ophthalmoscope in detecting non-proliferative DR was 94.47% and 90.91%, respectively, with a Kappa value of 0.900. The sensitivity and specificity of Daytona ultra-wide-field scanning laser ophthalmoscope in detecting proliferative DR was 90.00% and 100.00%, respectively, with a Kappa value of 0.926. The results of DR stage diagnosed by Daytona ultra-wide-field scanning laser ophthalmoscope were significantly correlated with FFA (r=0.921). Conclusions There is a high consistency between Daytona ultra-wide-field scanning laser ophthalmoscope and FFA in screening and staging DR in the elderly patients with cataract and DM.
