## **Core Concept**
Roth spots are retinal hemorrhages with white or pale centers composed of coagulated fibrin. They are a type of eye finding that can be associated with various systemic and ocular conditions. The presence of Roth spots indicates damage to the retinal vessels.

## **Why the Correct Answer is Right**
Roth spots are commonly seen in infective endocarditis. This condition involves infection of the heart valves, which can lead to septic emboli. These emboli can occlude retinal vessels, leading to retinal hemorrhages. The white center of Roth spots is thought to be due to coagulated fibrin or platelets. Infective endocarditis is a classic cause of Roth spots, making option **C. Infective endocarditis** the correct answer.

## **Why Each Wrong Option is Incorrect**
- **Option A:** While systemic lupus erythematosus (SLE) can cause various ocular manifestations, Roth spots are not as specifically characteristic of SLE as they are of infective endocarditis.
- **Option B:** Diabetic retinopathy can cause retinal hemorrhages but typically does not produce Roth spots with white centers.
- **Option D:** While retinal vasculitis can cause retinal hemorrhages, Roth spots are more specifically associated with conditions like infective endocarditis.

## **Clinical Pearl / High-Yield Fact**
A key clinical pearl is that Roth spots are a diagnostic clue for infective endocarditis, among other conditions. Their presence should prompt further investigation for systemic infection, especially in the appropriate clinical context.

## **Correct Answer:** C. Infective endocarditis
