**2. Congenital eye anomalies**

The congenital eye anomalies may appear in isolation or as part of a systemic syndrome. It may be genetically proven in some cases. Either germ line or somatic mutations can cause eye abnormalities. They may result from disruption, deformation, intrauterine infection or teratogenic exposure. Some anomalies significantly affect visual acuity. On the other hand, there are some anomalies which are noticed incidentally on routine eye check with no significance to the patient (Kherani & Robb, 2008).
