Red eye reflex checks are used for detecting which of the following?

Red eye reflex checks, commonly performed in pediatric assessments, are primarily used to detect abnormalities in the eye's structure, particularly the lens and the retina. A positive red reflex indicates that the light is properly passing through the lens, providing information on its clarity. If the reflex is absent or abnormal, it can signify conditions like leukocoria, which is an abnormal white reflection from the retina, often associated with serious eye conditions such as retinoblastoma or cataracts. Moreover, the presence of leukokoria can also suggest an increased risk for infections, including those in the TORCH complex (Toxoplasmosis, Other, Rubella, Cytomegalovirus, and Herpes Simplex Virus), which can have implications on infant health.

Therefore, the rationale for all options being correct rests on their inter-relatedness within the context of a red eye reflex check. This procedure allows for the detection of lens clarity issues, identification of leukocoria, and offers a diagnostic path towards assessing potential TORCH infections. In this way, the red eye reflex check serves as a crucial tool in early eye examinations to identify various ocular and systemic health concerns.
