Objective
To investage the relationship among the visual loss, the disease course, and retinal circulation time in patients with central retinal artery occlusion (CRAO)．
Method
The data about the central vision, disease course, and results of fundus fluorescein angiography (FFA) of 99 patients (99 eyes) with CRAO were statistically analyzed.
Results
Between 2 days and 21 days after the occurrence of CRAO, the disease course didnrsquo;t relate to the central visual loss (Pgt;0.05). In the retinal circulation, a correlation was found between the time of fluorescein perfusion and the central visual loss (Plt;0.05) but not between the time of arm-retina circulation and the central visual loss (Pgt;0.05).
Conclusion
In the duration of retinal circulation, the time of fluorescein perfusion in retinal artery relates to the central visual loss; the longer the duration is, the worse the vision is.
