| Objective To compare the diagnostic value of full range swept-source optical coherence tomography angiography(OCTA with fluorescein fundus angiography(FFA) for diabetic retinopathy(DR). Methods A total of 70 eyes of 35 patients with DR who received treatment in the Outpatient Ophthalmology Clinic of the Second Affiliated Hospital of Anhui Medical University from February 2022 to April 2022 were selected. Each patient was examined using ultra-widefield color fundus photography(UWF CFP). The patients' retinas were examined by full range swept-source OCTA and FFA respectively, and the differences in the detection rates of microaneurysm(MA), retinal neovascularization(RNV), nonperfusion areas(NPAs), intraretinal microvascular abnormalities(IRMA), diabetic macular edema(DME) were analyzed. Results The difference in the detection rates of MA, RNV, NPAs, IRMA, and DME in full range swept-source OCTA was not statistically significant compared with FFA(P>0.05), and the screening, diagnosis, and classification of DR by full range swept-source OCTA and FFA were in good agreement(Kappa value>0.75). Conclusions Full range swept-source OCTA has a broad prospect in the application of DR, which can be used as an important basis for non-invasive screening, diagnosis and follow-up of DR. |
