PURPOSE To determine the psychometric validity of the National Eye Institute-Visual Function Questionnaire (NEI VFQ-25) and its subscale structure for use in people with low vision. METHODS Two hundred thirty-two participants completed the NEI VFQ-25. Rasch analysis was used to test the psychometric performance of the questionnaire and each subscale. Factor models were hypothesized and tested...

PURPOSE Patient-reported measures of visual function are increasingly incorporated into clinical trials of new treatments for age-related macular degeneration (AMD). Limited information is available regarding the associations between distance visual acuity (VA), reading speed, or contrast sensitivity and the National Eye Institute Visual Function Questionnaire-25 (NEI VFQ-25) subscales judged r...

PURPOSE To evaluate the sensitivity to change, in patients who undergo vision rehabilitation, of the Veteran Affairs (VA) Low Vision Visual Functioning Questionnaire (LV VFQ-48), which was designed to measure the difficulty visually impaired persons have in performing daily activities and to evaluate vision rehabilitation outcomes. METHODS Before and after rehabilitation, the VA LV VFQ-48 was...

Background: The National Eye Institute 39-Question Visual Function Questionnaire (NEI VFQ-39) is an indicator of vision-related quality of life (QoL). The NEI VFQ-39 is used to assess the QoL in patients with non-infectious posterior uveitis, intermediate uveitis, or panuveitis, treated with subconjunctival (SCJ) or intravitreal (IVT) sirolimus as an immunomodulatory therapeutic (IMT) agent, de...

[Purpose] This research investigated the relationship between balance measured by a TETRAX and activities of daily living (ADL) assessed by NEI-VFQ 25. The results should provide basic data for rehabilitation therapy for low-vision patients. [Methods] We used the NEI-VFQ-25 vision-related Activities of Daily Living evaluation, MMSE-K, and TETRAX to evaluate 30 low-vision outpatients at K hospit...

BACKGROUND Non-visual factors influence a person's vision-related quality of life (VRQoL). The purpose of this study was to assess the relationship between health literacy and VRQoL in glaucoma patients. METHODS One hundred and ninety-five subjects with open-angle glaucoma participated in a cross-sectional patient survey and chart review. Subjects were administered a test of health literacy, ...

PURPOSE To measure and investigate visual functioning and health-related quality of life (QOL) in patients after ocular penetrating injuries (OPI). METHODS Fifty-four adult patients with OPI and 26 healthy control subjects were enrolled in the study. The National Eye Institute Visual Functioning Questionnaire (NEI VFQ-25) and the 36-Item Short Form Health Survey (SF 36) were administered. Soc...

PURPOSE Both the long form visual functioning scale (LFVFS(39)) and visual functioning scale (VFS) are measures of visual functioning (VF) that represent the Rasch-scaled versions of the NEI-VFQ(39) and the Indian vision function questionnaire (IND-VFQ), respectively. The objectives of this study were to investigate if the 15-item LFVFS(39) and 13-item VFS of the IND-VFQ meet the assumptions of...

AIMS To assess the relationship between depression and the vision-related quality of life in patients with retinitis pigmentosa (RP). METHODS The study included 144 patients diagnosed as having RP. The mean age of the patients was 38.5 (SD 13.3) years, and 42% of the subjects were women. They answered the National Eye Institute Visual Function Questionnaire (NEI-VFQ) to assess the vision-rela...
