Outcome measures
Primary outcome
Preliminary analysis revealed that the 12-session training had a positive influence on children’s performance on the task. The number of correctly found end-points, attained by adequately following the corresponding path, increased for both training groups. There was however a difference in the amount of increase between the two groups. On average, the group that has trained without the magnifier performed twice as good. That is, in the post-test they found twice as much correct end-point figures as compared to the pre-test. In the group that has trained with the magnifier, this number was four times as high. Now we are studying the rich data we collected to uncover the relevant variables that determine children’s progression and the differences between the groups. In addition we are looking for a possible transfer of this progression to other domains of their development (e.g., fine-motor skills).
Secondary outcome
1. How do young visual-impaired children work with a visual aid?
2. Can they perform the complex task of training and magnifier, and do they have a dominant hand and dominant eye?
Background summary
In this project the effect of training (game) is studied, on the abilities and willingness to use a visual aid (magnifier), in 2.5- to 6-years-old visually-impaired children.
Before and after a 6-weeks training period, children's abilities in using the magnifier are determined, as well as their overall ophthalmologic status, gross and fine motor skills, and overall level of development. The training is given to all children included in the study, one group is trained with the magnifier, the other group without the magnifier. In the pre-test and post-test, the same material is used as in the training.
The material consists of eight different patterns, each with four pathways made out of small symbols (LH), somewhat like 'ant trails'. The pathways either go horizontal, vertical or round, and they can cross each other. By following the paths with the magnifier, movements are induced in all directions. The goal of the task is to find the symbol at the end of the pathway corresponding to the symbol at the start. The size of the symbols is adjusted to each individual child's visual acuity.
Study objective
When young visual impaired children can participate in a training (game) in wich a magnifier is used, they learn to handle the magnifier (fine motor skills) they learn to observe small symbols (visual behaviour) and they become interested in the world of small things and know how to visualize these things.

Intervention
The experimental group trains with a magnifier. The control group trains without a magnifier.
The training (game) is the intervention. It is given twice a week (20 minutes) during 6 weeks.

The pathways either go horizontal, vertical or round, and they can cross each other. By following the paths with the magnifier, movements are induced in all directions.
