Assessment of pediatric visual acuity

The VA assessment of children within the different age groups is a very tough task somewhat due to of cooperation of children. However, the method of estimation of pediatric VA is based on different types of concern according to age. VA is a compound function of the minimum visibility, resolution, recognition and minimum discriminability. Sometimes the VA is hampered due to the types of refractive error and the initial correction of the error is also an important issue. The 5 to 6 years of age children with normal growth respond easily and they can be observed with the adult method but the youngest school-age children can be estimated with nonverbal methods. The growth of social and educational development of the children can retard due to acuity impairment but early detection and visual correction enhances the issue.The pathological disorders in childhood like corneal and lenticular disorders, macular degeneration, tumours, multiple sclerosis etc., turning of the eye from the standard called strabismus and it happens due to the reduction of the VA and the loss of binocular vision. Thus visual acuity is an approach for the assessment of ocular health along with the visual brain and its pathway.
