Coloboma is a very rare disease. In Switzerland only about 1 in every 50,000 – 150,000 live births have this malformation. However a recent study suggests that 1 in about 7400 people have this disorder (Nicks, 2011). It was first described in 1879 by Dr. O. Haab. Later more information was gathered to know its cause stemmed from the 22 chromosome. This defect led the eye to be abnormally shaped.
