Roth's spot

From Wikipedia, the free encyclopedia

Roth's spots are retinal hemorrhages with white or pale centers composed of coagulated fibrin. They are typically observed via fundoscopy (using an ophthalmoscope to view inside the eye).

They are usually caused by immune complex mediated vasculitis often resulting from bacterial endocarditis. Roth's spots may be observed in leukemia, diabetes, subacute bacterial endocarditis, pernicious anaemia, ischemic events, and rarely in HIV retinopathy.
