Congenital cataract is an opacification of the lens which is already present at birth or manifests itself during the first year of life (Kuhli-Hattenbach et al. 2008).

The intrauterine infectious diseases most frequently responsible for a congenital cataract are rubella, measles, herpes simplex, varicella, Epstein-Barr virus, influenza, Syphilis, and Toxoplasmosis.
