Tip 43: congenital cataracts

Absence of a red reflex is an important finding on newborn examination and could be caused by congenital cataracts (incidence 2.5/10,000).

The most common cause is idiopathic (50%) but they are also linked to Trisomy 21, intrauterine infections and maternal steroids. Early detection and referral is vital to minimize potential visual loss.
