Abstract
Homonymous hemianopsia is a visual field defect that has a negative impact on activities in daily life and quality of life. Due to a lack of high-quality research into the effectiveness of many rehabilitation methods, this project investigates the feasibility of a neuropsychological test battery, which is used to measure the effectiveness of two reading training interventions in homonymous hemianopsia patients. In this project, a case study was used by means of a mixed method design. The neuropsychological test results were quantitatively examined for validity and feasibility. In addition, a semi-structured interview was qualitatively analyzed to assess the feasibility of the neuropsychological assessment. Although deviant or low scores have been found on several tests (reading speed, verbal fluency professions and letter fluency, Bourdon-Wiersma), no unambiguous indication has been found in this project that shows that the neuropsychological tests used are insufficiently feasible for the target group homonymous hemianopsia. Despite this, various studies show that visual impairments may have negative effects on several vision-dependent neuropsychological tests and question the validity of these tests for people with a visual impairment. The effect of the visual impairment on the vision-dependent neuropsychological tests seems to be dependent of the characteristics of various patient groups. Homonymous hemianopsia patients seems to be able to compensate through eye and head movements by preserving vision in the remaining visual field. However, this project has also shown that testing should carefully deal with the complaints common for people with homonymous hemianopsia (altered light sensitivity, fatigue and reading problems) as these can have an effect on test performance. The findings from this project have led to recommendations for improvement of the validity and feasibility of the tests used in the neuropsychological assessment. In addition, some suggestion are made for follow-up research into the feasibility of neuropsychological assessment in homonymous hemianopsia patients. The current findings may contribute to the quality and feasibility of the research into the effectiveness of reading training interventions in people with homonymous hemianopsia. Keywords: Homonymous hemianopia, neuropsychological assessment, feasibility, validity
