AIM: To investigate the clinical value of fundus fluorescein angiography(FFA)and optical coherent tomography(OCT)in the diagnosis of central retinal vein occlusion.

METHODS: A total of 47 cases(47 eyes)central retinal vein occlusion were retrospectively analyzed from Jun. 2012 to Dec. 2015 in our hospital ophthalmology center. According to the final diagnosis, the results were divided into 21 cases of central retinal artery occlusion(group CRAO, 21 eyes)and central retinal vein occlusion(group CRVO, 26 eyes). All patients received FFA and OCT examination within 2wk of onset, and the image data of the two kinds of examination results were analyzed.

RESULTS: Group of patients with CRAO average macular foveola thickness, angle measuring, filling time determination results were significantly lower than that of the patients with CRVO group average and the differences were significant(P<0.05).

CONCLUSION:FFA and OCT images of central retinal artery and vein occlusion have their own characteristics, and the combination of these two images can be used to identify and diagnose the central retinal artery and vein occlusion.
