Complications of pheochromocytoma can include which of the following?

• A. Retinopathy
• B. Osteoporosis
• C. Anemia
• D. Hyperthyroidism

Answer: (A)

Pheochromocytoma causes episodic surges and sometimes sustained elevations of blood pressure due to excess catecholamines. The retina is highly sensitive to high pressure, so these hypertension spikes can lead to hypertensive retinopathy—damage to the retinal vessels that may include arteriolar narrowing, hemorrhages, and other signs of vascular stress. That connection makes retinopathy a recognized complication of this condition. The other options—osteoporosis, anemia, and hyperthyroidism—don’t have a direct, typical link to pheochromocytoma and its catecholamine-driven hypertension.
