CONCLUSIONS:Retinal arteriolar signs attributable to high blood pressure were associated with incident deep CMBs and late geographic AMD was associated with strictly lobar CMBs. Our findings suggest specific markers of retina may aid in identifying older people at high risk of developing CMBs in different regions.Disclosure: Dr. Ding has nothing to disclose.
