Are vision-specific quality of life questionnaires important in assessing rehabilitation for patients with hemianopia post stroke?

Objective: To explore the relationship between disability and functional measures with vision-specific quality of life (QoL) measures for people with hemianopia and stroke.
Method: The Behavioral Inattention Test (BIT) and the Mayo-Portland Adaptability Inventory (MPAI) were compared with scores on 2 vision-specific QoL measures, the National Eye Institute Visual Function Questionnaire (NEI VFQ-25) and Veteran Low Vision Visual Function Questionnaire (VA LV VFQ-48).
Setting: Rehabilitation hospitals in Adelaide, South Australia.
Participants: Stroke patients (n = 24) with homonymous hemianopia.
Results: Most of the BIT and MPAI scores were significantly associated with the NEI VFQ-25 and VA LV VFQ-48 scores. Behavioral test scores of the BIT and the MPAI total score correlated with more aspects of the QoL measures than the other components of the BIT and the MPAI.
Conclusion: BIT and MPAI measure constructs associated with QoL for people with hemianopia following stroke. Vision-specific QoL questionnaires can complement the functional instruments by identifying the domains of difficulty, based on the instrument's subscale, that can guide rehabilitation therapists to address the person's deficit.
