- A. Normal finding
- B. Abnormal finding, so child needs referral to ophthalmologist
- C. Sign of possible visual defect, so child needs vision screening
- D. Sign of small hemorrhages, which will usually resolve spontaneously
Correct Answer: A
Rationale: A brilliant, uniform red reflex during a funduscopic examination is considered a normal finding. The red reflex is caused by the reflection of light off the retina, specifically the blood vessels in the retina. A uniform red reflex indicates that the light is reflecting evenly from both eyes, suggesting symmetrical and clear lenses and corneas. This finding is typically seen in healthy individuals and is a reassuring sign of normal eye health.
