AIM: To investigate the relationship between carotid artery stenosis and ischemic ocular diseases.

METHODS: The clinical data of 30 cases(37 eyes)of patients with ischemic eye diseases were collected from November 2010 to May 2014, and they were accepted the fundus fluorescein angiography(FFA), transcranial Doppler(TCD)ultrasonic blood vessels of the eye, neck vascular color Doppler flow imaging(CDFI), the neck CT angiography(CTA)and carotid artery digital subtraction angiography(DSA)examination, and then the ischemic eye disease patients with ocular symptoms were analyzed. The peak systolic velocity(PSV)and resistance index(RI)of ophthalmic artery and central retinal artery were compared. Correlation between the internal carotid artery intima-media thickness(IMT)and ophthalmic artery, central retinal artery PSV and RI correlation risk; ipsilateral internal carotid artery plaque and ophthalmic artery PSV and RI; PSV and RI associated ipsilateral internal carotid artery plaque and central retinal artery were analyzed.

RESULTS: Eye symptoms: a black dim, reduced vision, the eyes flash, and around the eye pain were 75.7%, 83.8%, 51.4% and 32.4%; The eye signs: the dilatation of retinal vein, retinal hemorrhage, arterial stenosis and cotton spot and the contralateral side were regarded as main signs. Ophthalmic artery PSV and RI value of the differences were statistically significant(P<0.05); The contralateral side of the central retinal artery PSV and RI value of the differences were statistically significant(P<0.05); The ipsilateral internal carotid artery IMT and ophthalmic artery, central retinal artery PSV and RI were not correlated(P>0.05); The ipsilateral internal carotid artery plaque and ophthalmic artery PSV had no correlation with RI values(P>0.05); PSV and RI and the ipsilateral internal carotid artery plaque and central retinal artery had no correlation(P>0.05).

CONCLUSION: The incidence of ischemic eye diseases and internal carotid artery stenosis is associated with very close, the clinical can regard the degree of internal carotid artery stenosis as an important basis for diagnosis and treatment of eye diseases.
