Amblyopia is the most common vision problem in preschool children. It is a
decrease in vision in one or both eyes and arises without structural damage to
the eye or optic nerve. When amblyopia is undetected or left untreated, it results
in permanent vision loss that may adversely affect a person throughout life.

The incidence of amblyopia in the United States is estimated to be 3 to 5 % of
the population. This means that as many as 9,000 Iowa children under the age of
4 years suffer from poor vision in one or both eyes. If amblyopia is detected and
treated early in life, permanent visual loss can be prevented.
