Congenital cataract is a loss of transparency of the lens or capsule that causes visual impairment. Cataract is often associated with multiple malformations, and usually described as a part of a multisystem disorder, and at other times a result of infectious or hereditary conditions but some cases remain idiopathic. Counseling and diagnostic consideration for multisystem disorders, infections and hereditary condition should be performed promptly when fetal ophthalmic abnormalities observed. Here, we report a case of congenital cataract diagnosed during second trimester by ultrasonography.
