Congenital Developmental Anomalies Affecting the Eye and Orbit
In the human embryo, the eyes are formed by a delicate and complex process. Problems in this process can lead to congenital ((present at birth) eye malformations. These conditions are relatively rare, occurring in approximately five per 10,000 live births. Children with these problems often need specialized experience.
The human eye forms through a complex program during embryonic development. Problems in this developmental process can lead to congenital eye malformations, such as anophthalmia (no eye), microphthalmia (small eye), coloboma (failure of the optic fissure to close), aniridia (absent or partial iris), and optic nerve hypoplasia (underdeveloped optic nerve).
