Roth spots are seen in –
**Core Concept**
Roth spots are retinal hemorrhages associated with systemic conditions, characterized by a white or pale center surrounded by a red or purple halo. These lesions are indicative of a severe underlying condition affecting the coagulation and vascular systems.
**Why the Correct Answer is Right**
Roth spots are classically seen in conditions involving platelet aggregation, blood coagulation disorders, or vasculitis. The pathophysiology involves the formation of microthrombi in small retinal vessels, leading to retinal hemorrhages. Conditions such as endocarditis, systemic lupus erythematosus, and thrombotic thrombocytopenic purpura are commonly associated with Roth spots.
**Why Each Wrong Option is Incorrect**
**Option A:** While retinal hemorrhages can occur in diabetic retinopathy, Roth spots are not typically seen in this condition.
**Option B:** Although hypertensive retinopathy can cause retinal changes, Roth spots are not a characteristic feature.
**Option C:** Cataracts are a common cause of visual disturbances, but they are not associated with Roth spots.
**Clinical Pearl / High-Yield Fact**
Roth spots are a classic sign of systemic vasculitis and coagulation disorders, and their presence should prompt a thorough investigation into the underlying cause.
**Correct Answer:** D.
