[Carotid artery disease in patients with retinal vein and artery occlusion].
To evaluate carotid artery disease in patients with retinal vein occlusion (RVO) and with retinal artery occlusion (RAO), 41 RVO patients (male 21, female 20, mean age 63 +/- 12 years) and 59 RAO patients (male 39, female 20, mean age 66 +/- 12 years) were investigated. All patients were examined neurologically and underwent carotid ultrasound examination. Using carotid ultrasound, carotid artery disease was evaluated in terms of presence of plaque, echogenicity of the plaque, degree of stenosis, or presence of ulceration. Carotid plaque or occlusion of the carotid artery was observed more frequently in RAO patients than in RVO patients (ipsilateral side: p < 0.01, contralateral side: p < 0.001; Fisher's exact test). Heterogeneous plaque was found more frequently in RAO patients compared to RVO patients (ipsilateral side: p < 0.01, contralateral side: p < 0.02; Fisher's exact test). Ulcerated plaque was found only in patients with RAO. In conclusion, carotid artery disease was more frequently found in patients with RAO than in patients with RVO.
