PURPOSE To assess visual functioning and vision-specific health-related quality of life (HRQOL) in an older, community-dwelling-based population subsample, using the 25-item National Eye Institute Visual Function Questionnaire (NEI-VFQ-25). METHODS Three-quarters (76%, n = 892) of Extension Blue Mountains Eye Study participants (aged > or = 50 years, mean 60.8 years) completed the self-admini...

Purpose. The purpose of this study is to evaluate the vision related quality of life in patients with keratoconus by using the National Eye Institute Visual Function Questionnaire-25 (NEI-VFQ-25). Methods. Thirty patients presented with keratoconus (keratoconus group) and 30 healthy patients (control group) were included in this study. Twenty patients were using rigid gas permeable and 10 patie...

OBJECTIVE To assess the association of self-reported systemic and ocular comorbid disease and visual function in Latino subjects. METHODS National Eye Institute 25-item Visual Function Questionnaire (NEI-VFQ-25) and eye examination data were obtained from 5380 participants in the Los Angeles Latino Eye Study, a population-based prevalence study of eye disease in Latino subjects 40 years and o...

PURPOSE The aim of this study was to evaluate the impact of corneal cross-linking combined with photorefractive keratectomy (PRK) on blurring strength. METHODS A total of 63 patients with keratoconus were recruited for this study, and two study groups were formed according to the therapeutic intervention: corneal collagen cross-linking (CxL) group (33 patients) received corneal cross-linking ...

PURPOSE To validate a third-generation performance-based measure of visual function titled "Assessment of Disability Related to Vision" (ADREV) in a study population of patients with diabetic retinopathy. DESIGN Prospective, cross-sectional study. METHODS Patients with nonproliferative or proliferative diabetic retinopathy, free from ocular comorbidity, were recruited from a single institut...

Low vision devices in the past have been mainly extraocular. There are now four new devices in different stages of development and implementation that are currently available. Three of them, the Implantable Miniature Telescope (IMT, VisionCare Ophthalmic Technologies, Saratoga, CA), Intraocular Lens for Visually Impaired People (IOL-VIP, IOL-VIP System, Soleko, Pontecorvo, Italy), and Lipschitz...

It has been suggested that contact lens wear improves the visual function of patients with visual loss from congenital nystagmus. In this study, four patients with congenital nystagmus had two evaluations separated by at least one week (one with spectacles, one with contact lenses) including visual acuity, contrast sensitivity, oscillopsia scale, quality of life questionnaire (NEI VFQ-25), and ...

PURPOSE To assess the health-related quality of life in blepharoptosis patients and the impact after surgical management on their quality of life. METHODS Twenty-one patients with congenital or acquired blepharoptosis completed a questionnaire which was adapted from the Visual Function Questionnaire (VFQ), before and after surgical management. RESULTS Mean preoperative score was 74 and mean...

PURPOSE We examine the dimensionality of the 150-item visual functioning questionnaire for individuals with ultralow vision (ULV-VFQ) and develop representative abbreviated versions, facilitating clinical use, while retaining compatibility with a 17-item performance assessment. METHODS Subsets with 50 and 23 items covering the full difficulty range were selected, with evenly spaced item measu...
