What systemic disease is important to note in the family medical history of African Americans?

• A. Hypertension
• B. Diabetes
• C. Heart disease
• D. Sickle cell

Answer: (D)

Sickle cell disease is especially important to note in the family history for African Americans because it is more prevalent in this population and has a clear genetic basis that can impact the eyes. The abnormal hemoglobin causes red blood cells to sickle, which can block retinal vessels and lead to ischemia and new, fragile blood vessel growth (sickle cell retinopathy). This can progress to vision-threatening changes, so knowing about a family history raises your index of suspicion and informs you to perform thorough dilated retinal examinations and monitor for signs like neovascularization. While hypertension, diabetes, and heart disease are common concerns in many groups, they don’t carry the same strong, population-specific link to retinal complications as sickle cell in African Americans, making it the most pertinent systemic history to note.
