Abstract

The aim of this study was to investigate the association between central visual impairment and the characteristics of fundus fluorescein angiography (FFA) in patients with central retinal artery occlusion (CRAO). A total of 63 patients were diagnosed with CRAO by FFA. The visual dysfunction was classified into severe, mild and light degrees. Tropicamide was administered for mydriasis. FFA examination was performed using Heidelberg retinal tomography. The associations of age, gender and disease course with CRAO type were analyzed. Three types of manifestations were identified by FFA in 63 eyes, including poor perfusion (18 cases), exudation (22 cases) and mixed types (23 cases) of CRAO. No significant difference was found in age (F=0.171, P=0.844) and disease course (F=0.016, P=0.984) among the three types of CRAO. Similarly, no significant difference was found in gender among the three types of CRAO (χ2=0.176, P=0.916). The damage to vision caused by the exudation type of CRAO was not as severe as that caused by the poor perfusion and mixed types of CRAO. The distributions of damage severity caused by the poor perfusion and mixed types of CRAO were similar. In conclusion, the FFA observations for CRAO can be classified into three types of manifestations. The damage to vision in patients with CRAO is likely to be associated with poor perfusion in the retinal artery rather than exudation affecting the retina or optic disc. The patterns of clinical manifestations are not associated with age, gender or disease course.
