Amblyopia is defined as reduced and uncorrectable vision in a structurally 
normal eye. Early detection of amblyopia is very important. This can be 
accomplished through screening programs designed to identify amblyopia risk 
factors. Testing can be performed by trained teachers, technicians, school 
nurses and pediatricians as well as by eye care professionals. Once a child is 
identified as having an amblyopia risk factor it is crucial that the parents 
follow up with a pediatric ophthalmologist for a comprehensive examination. 
Amblyopia is the leading cause of monocular vision loss in the United States for 
adults under the age of 40. Amblyopia is amenable to therapy and is cost 
effective to treat. It is believed that earlier therapy for amblyopia provides 
better outcomes, but treatment has been shown effective even in some older 
children. In this paper, studies are cited regarding treatment of amblyopia.
