What symptom should a nurse expect in a toddler diagnosed with retinoblastoma?

In a toddler diagnosed with retinoblastoma, one of the hallmark symptoms to expect is the presence of a white eye reflex, also known as "leukocoria." This symptom manifests as a white color visible in the pupil when light is directed at it, which often becomes noticeable in photographs where a "white" or "yellow" reflection replaces the normal red-eye effect that is typically seen.

The appearance of leukocoria can indicate the presence of a tumor behind the lens of the eye, as the tumor can obstruct the normal light pathway and cause this abnormal reflection. Early recognition of this symptom is critical for timely diagnosis and management of retinoblastoma, which can significantly impact outcomes.

While strabismus, red eyes, and sensitivity to light may occur with various ocular conditions, they are not specific indicators of retinoblastoma and can be seen in other situations. Understanding leukocoria's significance in pediatric ophthalmology is important for healthcare providers.
