Abstract

Purpose: Amblyopia–the condition when the observer sees nothing and the patient very little. Eye-hand coordination develops gradually in infancy and continues through to pre-school age, so it is important to develop the child's motor skills through various activities and games during this period. Eye-hand coordination, also known as visual motor coordination, is the simultaneous interaction between the eyes and hands that results in a response to visual information captured by the visual system. Children with amblyopia are known to have impaired visual motor skills, which limits the child's daily activities and perception of the world around them. Children may have difficulty perceiving visual information, moving around in space, which affects their academic performance. Methods: There were 30 participants: 15 participants with amblyopia and 15 participants without vision problems who are divided into 3 age groups–5, 6 and 7 years. Twelve standard tasks, often used in kindergartens, were used in the work. The visual tasks were divided into different categories and was evaluated, as well as visual acuity of amblyopic eye and stereopsis, before and after the treatment. Results: The task for all children was the same, to complete all tasks as quickly and accurately as possible. Amblyopia has the greatest impact on visual tasks that require coordinated eye-hand interaction. In tasks that require drawing, finding and matching objects of the same shape, the completion time is independent of the presence of amblyopia. In tasks where the correct colour has to be indicated, the completion time of all items depends on age. Conclusions: If amblyopia has not been treated successfully in the childhood, it can cause the constant visual disturbance. It is important to assess how amblyopia affects motor skills and visual perception in pre-school children, as visual perception is important for children of this age for further self-development.
