Final answer:
Roth's spots are associated with bacterial endocarditis but can also occur in other conditions. They are retinal hemorrhages with white centers seen during an eye examination.
Step-by-step explanation:
Roth's spots are retinal hemorrhages with white or pale centers composed of coagulated fibrin, which are typically associated with bacterial endocarditis. Endocarditis is an infection of the inner lining of your heart (endocardium) that typically occurs when bacteria or other germs from another part of your body spread through your bloodstream and attach to damaged areas in your heart. While not exclusively present in endocarditis, Roth's spots are a classic sign and can occasionally be seen in other conditions such as leukemia, diabetes, and certain viral and bacterial infections. A thorough medical examination and testing are necessary to diagnose the underlying cause of Roth's spots.
