Conditions

Parial cortical blindness partial visual field defect

Interventions

The goal of Vistra is to learn patients to compensate for the visual field defect by training eye movements. Rotated Reading aims to reduce the effects of the visual field defect by learning people

Eligibility

Age

18 Years to 64 Years

Inclusion criteria

Inclusion criteria: In order to be eligible to participate in this study, a subject must meet all of the following criteria: * Homonymous visual field defect (at least a quadrantanopia, either right-sided or left-sided) due to acquired post-chiasmatic brain injury * At least three months between onset HVFD and the first measurement * Near visual acuity >

Exclusion criteria

Exclusion criteria: A subject who meets any of the following criteria will be excluded from participation in this study: * Additional visual field defect (at least cluster) in ipsilesional visual hemi-field * Pre-existing dyslexia/ illiteracy/ low literacy/ other pre-morbid reading problems * No clear neurological cause of HVFD * Presence of comorbid neglect The following criteria are made on the premise that, when present, they will impair the ability to successfully follow the intervention: * Communication difficulties (e.g. severe hearing impairment, no fluent understanding of Dutch language, severe aphasia as indicated by the Token test) * Negative advice of treatment team regarding reading intervention participation, due to e.g. severe psychiatric, cognitive or visual perception disorders, problems with health, motivation or illness awareness or misuse of drugs/alcohol/medication * Additional visual disturbances (e.g. diplopia, metamorphopsia, low contrast sensitivity)
