Which of the following is an indicator for referral for a child’s vision?

• A. 20/20 acuity
• B. Abnormal red reflex
• C. No history of nystagmus
• D. Age above 6 years

Answer: (B)

An abnormal red reflex is a significant indicator for referral for a child’s vision assessment. The red reflex test is a screening tool used in children to detect potential issues with the eyes, such as cataracts, retinoblastoma, or other ocular abnormalities. A healthy red reflex allows light to reflect evenly off the retina, producing a bright red or orange appearance in the pupillary area when viewed through an ophthalmoscope. If the reflex is abnormal—such as being absent, white, or dull—it may suggest underlying pathology that warrants further investigation by an eye care professional. This is crucial for early detection and management of ocular conditions, which can significantly impact a child's visual development.

The other options do not indicate the same level of concern. For instance, achieving 20/20 acuity suggests normal vision and is not a reason for referral. The absence of nystagmus, which is a condition characterized by involuntary eye movements, does not typically necessitate referral since it signifies a lack of abnormal eye movement rather than an issue needing intervention. Lastly, being older than 6 years does not serve as an indicator for referral unless accompanied by other significant findings, as vision development continues, and established visual acuity is more relevant to the assessment.
