What should a mother with a child showing leukokoria be tested for?

Leukocoria, the appearance of a white reflection in the pupil, can indicate several pathologies, including retinoblastoma, which is a malignant tumor of the retina predominantly found in children. Another concern with leukocoria is the potential involvement of TORCH infections—particularly with congenital rubella, which can lead to significant ocular abnormalities.

Testing for TORCH infections is particularly relevant as these infections can have serious implications for fetal and neonatal development. Identifying a TORCH infection early can aid in timely interventions and treatment, potentially improving outcomes for the child.

While genetic disorders and cataract formation might be associated with leukocoria, focusing on TORCH infections aligns with the immediate concerns regarding infections that can impact a child's overall health and development, particularly given the presence of leukocoria. Thus, testing for TORCH infections is an appropriate and critical step in the evaluation of a child presenting with this symptom.
