The retina, at the back of the eye, is light-sensitive. It is the part of the eye where light images come into focus. It develops its normal layers by about the 27th week of pregnancy. These layers receive light and light information, and transmit it to the brain for interpretation what we know as sight. Congenital Cataracts A congenital cataract is an eye problem that may occur at birth.
Most people believe cataracts only occur in old age, but that's a misconception.
Instead of being transparent or clear, the lens that focuses light onto the back of the eye is opaque or cloudy. This problem is usually caused by a genetic predisposition. Another congenital eye problem is microphthalmia, in which the overall size of the eye is too small. The eyeball may be only two-thirds its normal size. This abnormality often occurs with other abnormalities of the eyes.
