Q: Roth spots (see picture below) - Do they interfere with vision?
A) Yes
B) No
Answer: No
These "white-centered" hemorrhages are not specific for bacterial endocarditis. They probably reflect microinfarcts and occur in essential hypertension, HIV, connective tissue disease, severe anemia, Behçet's disease, viremia, and hypercoagulable states.
They do not interfere with vision.
