AIM: To investigate the diagnostic value of fundus fluorescein angiography(FFA)and optical coherence tomography(OCT)in the diagnosis of diabetic macular edema(DME).

METHODS: From January 2015 to January 2016, selected 62 patients(101 eyes)with diabetic retinopathy(DR)in our hospital, underwent FFA and OCT respectively. We compared the results of the two methods.

RESULTS: The detection rate of DME by FFA was 84.2%, and the detection rate of DME by OCT was 77.2%, the difference was not statistically significant(P>0.05). In 101 eyes, OCT and FFA all showed macular edema in 76 eyes, and no macular edema in 14 eyes, the diagnostic accuracy of OCT and FFA was 89.1%, Kappa was 0.653, and the consistency was higher(P<0.05). Macular central retinal thickness difference was statistically significant in patients with different FFA features(P<0.05), the diffuse edematous retinal thickness was 301.43±62.44SymbolmA@m, which was significantly thicker than the other patients.

CONCLUSION:OCT can objectively examine the structural changes of the macular area in diabetic patients, but it cannot replace the role of FFA in the diagnosis of macular edema, the combination of the two methods is helpful in the diagnosis of DME.
