Which combination of findings are typical signs of increased intracranial pressure in infants?

• A. Sunset eyes
• B. All of the above
• C. Increased head circumference with bulging fontanelle
• D. Irritability and poor feeding

Answer: (B)

In infants, signs of increased intracranial pressure often appear in several ways at once because the skull is still growing and the brain is under pressure. Sunset eyes reflect pressure on the midline vision pathways, causing the eyes to appear driven downward with sclera visible above the iris. The increased pressure can also cause the fontanelle to bulge and the head circumference to rise as the skull expands and CSF builds up. Irritability and poor feeding happen because brain pressure affects arousal, discomfort, and autonomic regulation, leading to fussiness and feeding difficulties. Together, these signs form a typical pattern of raised ICP in infants, so recognizing all of them together points strongly to the same problem and warrants urgent assessment.
