The nurse is performing an eye-screening clinic at a daycare center. When examining a 2-year-old child, the nurse suspects that the child has a "lazy eye". What should the nurse do next?

A. Assess child's ability to read: A 2-year-old is too young for a standard reading assessment, as they may not yet recognize letters. Visual acuity tests for this age group typically use pictures or symbols rather than reading letters. Assessing reading ability would not be appropriate or useful in diagnosing strabismus, as the condition affects eye alignment rather than literacy skills. B. Consider this a normal finding: Strabismus, or "lazy eye," is not a normal finding beyond infancy. If left untreated, it can lead to amblyopia (permanent vision loss in the weaker eye). Early detection and intervention are crucial for proper visual development, and dismissing the finding as normal could result in a missed opportunity for corrective treatment, such as patching or corrective lenses. C. Assess the child's visual fields with the confrontation test: The confrontation test assesses peripheral vision, not strabismus. It is more appropriate for older children and adults, as it requires the child to understand and follow instructions. While it can identify visual field deficits, it does not evaluate binocular vision or eye misalignment, which are essential in diagnosing strabismus. D. Test for strabismus by performing the corneal light reflex test (Sparkle Test): The corneal light reflex test evaluates eye alignment by shining a light at the child's eyes and observing the reflection on the corneas. If the light reflex is asymmetrical, it suggests strabismus, which requires further evaluation and possible treatment. Early detection is critical to prevent amblyopia, and this simple test is a quick and effective method to screen for misalignment in young children.
