Samenvatting

Background: Homonymous visual field defects (HVFDs) are a common consequence of posterior brain injury and may have a substantial influence on ADL and participation in society. In this study we analysed self-reported visionrelated difficulties in daily life in a group of patients with HVFDs.
Methods: Fifty-four patients with homonymous hemianopia or quadrantanopia but without visual or cognitive comorbidities were selected from a larger sample (n=373) of patients with HVFDs. Participants had visual acuity ≥ 0.5 (6/12, 20/40), intact oculomotor functions, MMSE score ≥ 24 and no symptoms of impaired spatial cognition, visual attention, agnosia, memory problems, depression or anxiety disorder. Three standardized questionnaires were completed during a structured interview: National Eye Institute Visual Functioning Questionnaire, Independent Mobility Questionnaire, and Cerebral Visual Disorders. The reported difficulties were linked to the International Classification of Functioning, Disability and Health (ICF).
Results: Apart from well-known difficulties related to reading, orientation, and mobility, a large proportion of patients with HVFDs reported problems that previously have not been documented in the literature, such as impaired light sensitivity, colour vision, and depth perception.
Discussion: Our findings have implications for future study, assessment and rehabilitation of patients with HVFDs. More research is needed on the neural, psychological, or other mechanisms underlying the impaired light sensitivity, colour perception and perception of depth in patients with HVFDs.
