Abstract
OBJECTIVE: There is ongoing controversy with regard to the stability of calcified carotid artery plaques (CCAPs) seen in the bifurcation area on panoramic images (PIs). Therefore, we sought to evaluate the possibility of these plaques shedding emboli by observing their relationship with ipsilateral retinal emboli.
STUDY DESIGN: The study group included 50 neurologically and visually asymptomatic males with diabetes, with PIs that incidentally demonstrated CCAPs (CCAP+) and contemporaneous digital retinal images that had been obtained for evaluation of diabetic retinopathy. The control group consisted of 50 males with diabetes who were matched for age and body mass index and had undergone both imaging studies and whose PIs were devoid of carotid plaques (CCAP-). The presence of retinal emboli was determined by two ophthalmologists blinded to the patients' medical histories, and the prevalence rates for the two groups were calculated.
RESULTS: The presence of asymptomatic retinal arteriolar emboli was found in the eye ipsilateral to the radiographically observed carotid atheroma in 10 of 50 (20%) of the patients in the CCAP+ group, compared with 2 of 50 (4%) in the CCAP- group, and this difference was statistically significant (Fisher's exact P < .03).
CONCLUSIONS: Some male patients with diabetes mellitus type II having calcified carotid artery atheromas in the bifurcation area, as visualized on PIs, may have significant sequelae as evidenced by retinal artery emboli.
