- Primary Outcome Measures
Name Time Method Can specific computer-based reading training improve the reading ability of patients with homonymous hemianopia?<br>Is text rotation and vertical reading of functional benefit for patients with homonymous hemianopia because patients can shift the text into their seeing hemifield?<br><br>The reading speed is measured:<br>- during the training, documented by the training software program (between T1 and T2)<br>- During the examination appointments (T1, T2 and T3) with standardized, printed on paper, reading texts (IReST) and during the measurement of eye movements when reading texts (Radner texts) on the screen.<br><br>Additionally, eye movement parameters are measured (number of forward saccades, number of regressions, amplitude size, etc...).
- Secondary Outcome Measures
Name Time Method Which representation of the reading text is best suited for homonymous hemianopia, horizontal or vertical?<br>Which patients benefit from the training?<br>Does Reading Training Improve Cognition and Quality of Life?<br><br>Parameters to be measured, see primary endpoint.<br>Comparison of the two groups Arm 1 and Arm 2.<br>Calculation of correlations with patient data (e.g. age at examination, age at onset of disease, duration of disease, side of visual field defect, etc...).
