If weak-sightedness is present, the brain cannot correctly process visual impressions. Weak-sightedness can occur if eyesight in children has not developed correctly, if refractive power varies between the eyes (anisometropia) or if visual defects or a squint have not been treated.
Diagnosis and treatment
Amblyopia can be detected even in infancy by means of an eye test. In the process, the refractive power of the eyes, the ocular fundus and possible misalignments are examined. In order to facilitate the visual impressions of the weak eye for the brain, the healthy eye is covered with an eye patch (occlusion therapy). When combined with glasses adapted to the therapy, the brain and eye can develop normally again.
