Primary Outcome Measures

Name	Time	Method
<p>1. Humphrey and Goldmann perimetry (subjective enlargement of the visual<br /><br>field). De Humphrey is an automated perimeter. The Goldmann perimeter is an<br /><br>original that is converted into an automatic perimeter, leading to both<br /><br>perimetry methods being unbiased. Humphrey provides static perimetry:<br /><br>defect-depths measured in relatively low resolution. Goldmann provides dynamic<br /><br>perimetry: measures the border between 'non-responsive' and 'responsive' fields<br /><br>in higher resolution.<br /><br><br /><br><br /><br>De effects of training vs non-training are deduced from the differences between<br /><br>improvement in trained areas vs de improvement in non-trained areas.</p><br>

Secondary Outcome Measures

Name	Time	Method
<p>2. reading test (reading speed)<br /><br>3. Goal Attainment Scaling. This concerns the degree in which previously<br /><br>determined goals are reached during/after training. This in rehabilitation<br /><br>regularly used assessment method means that goals are identified, which are<br /><br>- specific (unambiguous goal)<br /><br>- measurable<br /><br>- acceptable or relevant to the patient<br /><br>- realistic/attainable</p><br>
