Objective  To observe the clinical features of combined central retinal artery and vein occlusion. Methods  The clinical data of eight patients of combined central retinal artery and vein occlusion diagnosed by fundus examination and fundus fluorescein angiography (FFA) was analyzed retrospectively, including the causes, fundus manifestations and FFA features. Results  4/8 patients had hypertension and dyslipidemia, 2/8 patients had traumatic retrobulbar hemorrhage, one patient had orbital cellulitis and one patient had systemic lupus erythematosus. All the patients had posterior pole retinal edema, hemorrhage, thin retinal artery, dilated vein, and papilledema. FFA showed delayed arterial filling, and there was no filling of retinal arterial branches until the late stage of FFA. Laminar flow delayed in large retinal veins, and there was no filling or only retrograde filling in retinal vein branches. Large areas with dot-like or patchy weak choroidal fluorescence can be observed in five patients. Conclusions  Combined central retinal artery and vein occlusion is rare with complex etiology. The fundus manifestations and FFA features are atypical, but have features of central retinal artery occlusion and central retinal vein occlusion.
