Is amblyopia only bad vision ?

Amblyopia results from an abnormal binocular interaction, in the context of strabismus or uncorrected refractive errors, or from visual deprivation. Screening is important during pre-school years in order to start treatment while cerebral plasticity is optimal. Screening practices vary a lot between developed countries, with consequences on public health policies. Screening is based on the measure of visual acuity in young children. The technique of sweep visual evoked potentials allows an objective measure of visual acuity, without requiring participants to name optotypes, which is useful in pre-verbal children. Along with decreased visual acuity, amblyopia is associated with an absence of improvement with age of the characteristics of saccades. With respect to motor skills, altered binocular vision affects catching skills and balance. A better understanding of these deficits will allow for better treatment of amblyopia, which is the first cause of monocular vision loss in children.
